    ABSTRACT: Plant-derived smoke and smoke-isolated compounds stimulate germination in seeds from over 80 genera. It has also been reported that smoke affects overall plant vigour and has a stimulatory effect on pollen growth. The effect of smoke on orchid seeds, however, has not been assessed. In South Africa, orchid seeds from several genera may be exposed to smoke when they are released from their seed pods. It is therefore possible that smoke may affect their germination and growth. Therefore the effects of smoke [applied as smoke-water (SW)] and two smoke-derived compounds, karrikinolide (KAR1 ) and trimethylbutenolide (TMB), were investigated on the germination and growth of orchid seeds in vitro. The effect of SW, KAR1 and TMB were investigated on the endangered epiphytic orchid, Ansellia africana, which is indigenous to tropical areas of Africa. Smoke-water, KAR1 and TMB were infused in half-strength MS medium. The number of germinated seeds and the number of seeds and protocorm bodies to reach predetermined developmental stages were recorded on a weekly basis using a dissecting microscope for a 13 week period. Infusing SW 1:250 (v:v) into half-strength MS medium, significantly increased the germination rate index (GRI) and the development rate index (DRI) of the A. africana seeds. All the SW treatments significantly increased the number of large protocorm bodies at the final stage of development. Infusing KAR1 into the growing medium had no significant effect on the germination or development of the seeds. The TMB treatment, however, significantly reduced the GRI and DRI of A. africana seeds.

    ABSTRACT: Variations in seed characteristics observed in heteromorphic species may affect various stages of their life cycles, e.g. seed dormancy, germination characteristics or even adult plant performance. Highly specialized seed morphs - described as colonizers and maintainers - exhibit a trade-off between colonization capacity and competitive traits. The performance of distinct seed morph progenies under competitive conditions, and especially in multi-species arrangements, had previously not been given much attention. In this study, we compared performance and response to competition among distinct seed morph progenies in two congeneric, co-occurring species: the invasive Bidens frondosa and the non-invasive Bidens tripartita. We hypothesized that maintainer seed morphs of both species would perform better under increased plant densities and within intermorphic mixtures, while colonizer morphs would show stronger responses to increased densities and perform relatively poorly in intermorphic mixtures. We conducted a growth trial and a greenhouse experiment which revealed that seed morph progenies differed significantly in plant height when grown without competition, while under competitive conditions such differences became less apparent. The observed pattern was more strongly pronounced in B. frondosa, which showed a general predominance in stature and biomass over its non-invasive congener. Although seed morphs performed equally well under competitive conditions, as reported by previous studies, increased plant height and more rapid germination can favour the maintainer seed morph on sites where vegetation is already present.

    ABSTRACT: Leaf senescence is an important physiological process during the plant life cycle. However, systemic studies on the impact of microRNAs (miRNAs) on the expression of senescence-associated genes (SAGs) are lacking. Besides, whether the other Argonaute 1 (AGO1)-enriched sRNAs play regulatory roles in leaf senescence remains unclear. In this study, a total of 5,123 and 1,399 AGO1-enriched sRNAs, excluding miRNAs, were identified in Arabidopsis (Arabidopsis thaliana) and rice (Oryza sativa), respectively. After retrieving the SAGs from Leaf Senescence Database, all of the AGO1-enriched sRNAs and the miRBase-registered miRNAs of the two plants were included for target identification. Supported by degradome signatures, 200 regulatory pairs involving 120 AGO1-enriched sRNAs and 40 SAGs, and 266 regulatory pairs involving 64 miRNAs and 42 SAGs were discovered in Arabidopsis. Moreover, 13 genes predicted to interact with some of the above identified target genes at protein level were validated to be regulated by 17 AGO1-enriched sRNAs and 10 miRNAs in Arabidopsis. In rice, only one SAG was targeted by three AGO1-enriched sRNAs, and one SAG was targeted by miR395. However, five AGO1-enriched sRNAs were conserved between Arabidopsis and rice. Target genes conserved between the two plants were identified for three of the above five sRNAs, pointing to the conserved roles of these regulatory pairs in leaf senescence or other developmental procedures. Novel targets were discovered for three of the five AGO1-enriched sRNAs in rice, indicating species-specific functions of these sRNA-target pairs. These results could advance our understanding of the sRNA-involved molecular processes modulating leaf senescence. This article is protected by copyright. All rights reserved.

    ABSTRACT: After-ripening is a common method for dormancy release in rice. In this study, the variety Jiucaiqing (Oryza sativa L. subsp. japonica) was used to determine the dormancy release by different after-ripenings (1, 2 and 3 months). The germination speed, germination percentage and seedling emergence were increased with after-ripening; a greater than 95% and 85% germination percentage and seedling emergence were observed after one month of after-ripening within 10 days of imbibition, respectively, while less than 45% and 20% germination percentage and seedling emergence in the freshly harvested seeds. By comparison, three months of after-ripening could be considered as a suitable treatment period for rice dormancy release. Dormancy release by after-ripening is mainly correlated with the rapid decline of ABA content and the increases of IAA content during imbibition. Subsequently, the GA1 /ABA, GA7 /ABA, GA12 /ABA, GA20 /ABA and IAA/ABA ratios were significantly increased while GA3 /ABA, GA4 /ABA and GAs/IAA ratio was significantly decreased in imbibed seeds after 3 months of after-ripening thereby altering the α-amylase activities during seed germination. The peak of α-amylase activities occurred at the earlier germination stage in after-ripened seeds than the freshly harvested seeds. The expressions of ABA, GA and IAA metabolism genes and dormancy related genes were regulated by after-ripening upon imbibition. The increased expressions of OsCYP707A5, OsGA2ox1, OsGA2ox2, OsGA2ox3, OsILR1, OsGH3-2, qLTG3-1 and OsVP1 while decreased expression of Sdr4 were obviously observed in imbibed seeds after 3 months of after-ripening. The dormancy release by after-ripening might be involved in the weakening of tissues covering embryo though qLTG3-1 and in the decreased ABA signaling and sensitivity though Sdr4 and OsVP1.

    ABSTRACT: Biotic pollination is critical for tropical ecosystems' functioning, and nectar plays an essential role as it represents the main trophic resource for pollinators. Nevertheless, little is known about the mechanisms that underlie its production, which is essential for understanding the basis of nectar-mediated interactions in ecological and evolutionary approaches. Therefore, this study explores the relationship between the nectar secretion pattern and nectary functional changes in Anemopaegma album, a bee-pollinated species. We analysed the pattern of nectar production under field conditions and investigated floral nectary structural changes in two different developmental stages using light, transmission and scanning electron microscopy. We measured 30.95 ± 23.02 μL (mean ± sd, n=30) of nectar accumulated inside the nectar chamber (29.26 ± 3.48% of sucrose equivalents) at the moment of flower opening. Nectar removal didn't influence the pattern of floral nectar production in terms of volume or total sugar but reduced the concentration of the nectar produced during the first 24 hours of anthesis. The nectary consisted of an epidermis, a nectary parenchyma, and a subnectary parenchyma supplied only by phloem. Starch grains decreased in size and abundance from the subnectary parenchyma toward the epidermis. We observed the degradation of starch grains and the incorporation of amyloplasts into vacuoles at the pre-anthesis stage as well as the transformation of amyloplasts into elaioplasts during anthesis. Nectar secretion was continuous during the Anemopaegma album flower lifespan, which was related to the functional features of its floral nectary, especially the presence of starch stored in the parenchyma.

    ABSTRACT: Standing dead biomass retention is considered one of the most relevant fuel structural traits to affect plant flammability. However, very little is known about the biological significance of this trait and its distribution between different functional groups. Our aim was to analyse how the proportion of dead biomass produced in Mediterranean species is related to the successional niche of species (early-, medium- and late-successional stages) and the regeneration strategy of species (seeders and resprouters). We evaluated biomass distribution by size classes and standing dead biomass retention in nine dominant species from the Mediterranean Basin in different development stages (5, 9, 14 and 26 years since the last fire). The results revealed significant differences in the standing dead biomass retention of species that presented a distinct successional niche or regeneration strategy. These differences were restricted to the oldest ages studied (>9 years). Tree and small tree resprouters, typical in late-successional stages, presented slight variations with age and a less marked trend to retain dead biomass, while seeder shrubs and dwarf shrubs, characteristic in early-successional stages, showed high dead biomass loads. Our results suggest that the species that tend to retain more dead branches are colonising species that may promote fire in early-successional stages. This article is protected by copyright.

    ABSTRACT: The abundance and distribution of species can be ascribed to both environmental heterogeneity and stress tolerance, with the latter measure sometimes associated with phenotypic plasticity. Although phenotypic plasticity varies predictably in response to common forms of stress, we lack a mechanistic understanding of the response of species to high saline-sodic soils. We compared the phenotypic plasticity of three pairs of high and low saline-sodic tolerant congeners from the families Poaceae (Leymus chinensis vs. L. secalinus), Fabaceae (Lespedeza davurica vs. L. bicolor) and Asteraceae (Artemisia mongolica vs. A. sieversiana) in a controlled pot experiment in the Songnen grassland, China. The low tolerant species, L. secalinus and A. sieversiana exhibited higher plasticity in response to soil salinity and sodicity than their paired congeners. High tolerant species, L. chinensis and A. mongolica, had higher values for several important morphological traits such as shoot length and total biomass under the high saline-sodic soil treatment than their paired congeners. In contrast, congeners from the family Fabaceae, L. davurica and L. bicolor, did not exhibit significantly different plasticity in response to soil salinity and sodicity. All species held a constant reproductive effort in response to saline-sodic soil stress. The different responses between low and high tolerant species offers an explanation for the distribution patterns of these species in the Songnen grassland. High tolerant species showed less morphological plasticity over a range of saline-sodic conditions than their paired congeners, which may manifest as an inability to compete with co-occurring species in locations where saline-sodic soils are absent.

    ABSTRACT: Herbivorous insects can cause deep cellular changes to plant foliage following infestations depending on feeding behavior. Here, a proteomic study was conducted to investigate green peach aphid (Myzus persicae Sulzer) influence as a polyphagous pest on the defense response of Arabidopsis thaliana (L.) Heynh after aphid colony set up on host plant (3 days). Analysis of about 574 protein spots on 2-DE gel revealed 31 differentially expressed protein spots. Twenty out of 31 differential proteins were selected to be analyzed by mass spectrometry. From 12 out of the 20 analyzed spots, we identified 7 and 9 proteins by MALDI-TOF-MS and LC-ESI-MS/MS, respectively. Twenty five percents of the analyzed spots contain a couple of proteins. Different metabolic pathways were modulated in Arabidopsis leaves according to aphid feeding: most of them corresponded to carbohydrate, amino acid and energy metabolism, photosynthesis, defense response and translation. This paper has established a survey of early alterations induced in the proteome of Arabidopsis plants by the M. persicae aphids. It provides valuable insights to uncover the complex response of plants to biological stress, particularly with herbivorous insects with sucking feeding behavior.

    ABSTRACT: Floral phenotypes are considered a product of pollinator-mediated selection, which also has the side effect of decreasing floral variation within species. Correlates of flower visibility and function were studied in a carnation species (Dianthus inoxianus) which has crepuscular anthesis and scent-based pollination by the hawkmoth Hyles livornica. We also assessed constancy of flower form in nature and in cultivation and, using fruit-set as an estimate of plant relative fitness, tested whether the main pollinator exerted phenotypic selection on floral traits. Petal claw, which is roughly equivalent to the average depth at which an insect's proboscis must be inserted to reach nectar, was remarkably constant among wild plants (coefficient of variation 8%). In contrast, the area of the visible part of the petal, and the intensity of a colored dot pattern on the petal varied much (respectively CV = 34% and 102%). Cultivation in a common environment revealed significant variation among genotypes as regards petal area, degree of laciniation, and extension of the dot pattern, but not petal claw length which remained steady . Neither petal area, shape, nor color did affect relative fitness during the year of study, but plants with intermediate petal claws (i.e., floral tubes) set significantly more fruit. Results are compatible with low response of the main pollinator to variation in visual traits (petal area, laciniation, color) and high responsiveness to variation in others (tube length). Inconsistent phenotypic selection by pollinators may add to other causes of floral variation in the genus Dianthus, which are discussed. This article is protected by copyright. All rights reserved.

    ABSTRACT: Apomixis is an asexual seed reproduction mechanism thorough which embryos are originated from material tissues inside the ovules, without precedent fertilization. It allows plants to colonize new habitats, even in places where flower visitors are scarce or where plants are isolate. Apomixis seems to be related to pollen sterility and, in species with flowers that offer pollen as a reward for pollinators, the amount or quality of the pollen offered by these species may influence the amount of the visits and specific composition of the visitors. In order to test this hypothesis, we studied breeding systems of 16 species of Melastomataceae and their flower visitors, evaluating composition and abundance of the visits to apomictic and sexual species. Apomictic plants with no viable pollen or with pollen with low viability did not receive visits from pollinators, and consequently probably produce strictly apomictic fruits. On the other hand, apomictic and sexual plants with high pollen viability do receive visits; in this case, apomictic plants may produce fruits and seeds through both sexual and apomictic ways. The species composition of insects visiting Melastomataceae with high pollen viability was similar, regardless if the plants were apomictic or not. It seems that pollen viability levels are important to determine the visits to the flowers irrespective of breeding systems. This article is protected by copyright. All rights reserved.

    ABSTRACT: Genetic diversity is important for species' fitness and evolutionary processes but our knowledge on how it varies across a species distribution range is limited. The abundant centre hypothesis (ACH) predicts that populations become smaller and more isolated towards the geographic range periphery - a pattern that in turn should be associated with decreasing genetic diversity and increasing genetic differentiation. We tested this hypothesis in Adonis vernalis, a dry grassland plant with an extensive Eurasian distribution. Its life history traits and distribution characteristics suggest a low genetic diversity that decreases and a high genetic differentiation that increases towards the range edge. We analyzed AFLP-fingerprints in 28 populations along a 4698 km transect from the geographic range core in Russia to the western range periphery in Central and Western Europe. Contrary to our expectation, our analysis revealed high genetic diversity (range of proportion of polymorphic bands = 56-81%, He = 0.168-0.238) and low genetic differentiation across populations (ΦST = 0.18). However, in congruence with the genetic predictions of the ACH, genetic diversity decreased and genetic differentiation increased towards the range periphery. Spanish populations were genetically distinct suggesting a divergent post-glacial history in this region. The high genetic diversity and low genetic differentiation in the remaining A. vernalis populations is surprising given the species' life-history traits and points to the possibility that the species has been widely distributed in the studied region or that it has migrated from a diverse source in an East-West direction, in the past.

    ABSTRACT: The paramount role of cytokinins (CKs) in the initiation, as well as the prevention, of senescence is well established. In recent years, experimental methods have become available to raise and lower the CK concentration and experimentally manipulate senescence. Decapitating the apical shoot and add the synthetic auxin naphthylacetic acid to the cut stem reduced endogenous CKs to low levels. Conversely, if no auxin was applied, xylem- and leaf CK levels increased dramatically, indicating that basipolar auxin transport is a key determinant in the synthesis of CKs and is potentially more important than NO3 . Manipulating the concentration of applied NO3 caused considerable variation in leaf CK levels and concomitant changes in senescence. These and other results suggest that the frequently discussed decrease in nitrogen use efficiency (NUE) may be more heavily regulated by CKs than by NO3 . Analysis of the re-metabolisation and re-allocation of chlorophyll, proteins, amino acids, and starch in three different cucumber cultivars indirectly showed that these metabolites were significantly affected by the concentration of CKs in the leaves. Further research in this area may allow leaf senescence and plant yield to be more efficiently regulated by manipulating CKs and/or IAAPAT instead of nitrate. This article is protected by copyright.

    ABSTRACT: Biocrusts (biological soil crusts) cover open spaces between vascular plants in most arid and semi-arid areas. Currently, information about the effects of biocrusts on seedling growth of vascular plants is controversial, and little attention has been given to their effect on plant growth and physiological characteristics along with the growing periods. Here, we conducted experiments to elucidate the impact of biocrusts on growth and physiological characteristics of three habitat-typical plants, Erodium oxyrrhynchum, Alyssum linifolium, and Hyalea pulchella, which growing in the Gurbantunggut desert, Northwest China. The influences of biocrusts on variations of biomass accumulation, average leaf area, leaf relative water content, photosynthesis, maximum quantum efficiency of PSII photochemistry (Fv /Fm ), chlorophyll content, osmotic solutes (soluble sugar, protein and proline) and antioxidant enzymes (superoxide dismutase, catalase and peroxidase) were investigated in three species grown in sites with or without biocrusts covers. The biomass, average leaf area, leaf water content, photosynthesis, Fv /Fm and chlorophyll content of the three species in crusted soils were found to be higher than those in uncrusted soils in the early growing period and lower in the later part of the growing period. Soluble sugar and proline contents and antioxidant enzyme activities were always higher in crusted soils than those in uncrusted soils. In contrast, soluble protein contents were always lower. Taken together, these findings indicated that biocrusts have different effects on the three ephemeral species during their whole growing period in this desert, primarily via their effects on soil moisture, and possibly through their effect on soil nutrients. The present study showed that the influence of biocrusts on growth of vascular plants is not consecutive during the whole growing period of plants. In their early growing period, biocrusts had either positive effects or no effects on these growth and physiological parameters. However, biocrusts tended to negatively influence them in the later part of the growing period. Our results provide a new angle to explain why biocrusts have exhibited differing effects on vascular plant growth in previous studies. This article is protected by copyright. All rights reserved.

    ABSTRACT: The interactions between macrophytes and water movement are not yet fully understood, and the causes responsible for the metabolic and ultra-structural variations in plant cells as a consequence of turbulence are largely unknown. In the present study, the growth, metabolism and ultra-structural changes were evaluated in the aquatic macrophyte, Elodea nuttallii, after exposure to turbulence for 30 days. The turbulence was generated with a vertically oscillating horizontal grid. The turbulence reduced plant growth, plasmolyzed leaf cells and strengthened cell walls, and the plants exposed to turbulence accumulated starch granules in stem chloroplasts. The size of the starch granules increased with the magnitude of the turbulence. Using capillary electrophoresis-mass spectrometry (CE-MS), an analysis of the metabolome found metabolite accumulation in response to the turbulence. Asparagine was the dominant amino acid that was concentrated in stressed plants, and organic acids such as citrate, ascorbate, oxalate and γ-Amino butyric acid (GABA) also accumulated in response to the turbulence. These results indicated that turbulence caused severe stress that affected plant growth, cell ultra-structure and some metabolic functions of E. nuttallii. Our findings offer insights to explain the effects of water movements on the functions of aquatic plants. This article is protected by copyright. All rights reserved.

    ABSTRACT: Biochemical and physiological traits of two soybean [Glycine max (L.) Merr.] genotypes that differ in sensitivity to ozone (O3 ) were investigated to determine the possible basis for the differential response. Fiskeby III (O3 -tolerant) and Mandarin (Ottawa) (O3 -sensitive) were grown in a greenhouse supplied with charcoal-filtered air for four weeks. Plants were then treated with O3 for 7 h d(-1) in greenhouse chambers. Mandarin (Ottawa) showed significantly more visible leaf injury and hydrogen peroxide and superoxide production compared with Fiskeby III. Peroxidase activity in O3 -sensitive Mandarin (Ottawa) was 31% higher in the elevated O3 treatment but it was not significantly different in O3 -tolerant Fiskeby III. Ozone did not affect superoxide dismutase or glutathione reductase activities, or the leaf tissue concentrations of glutathione or ascorbic acid concentrations. Thus, variation in O3 response between the Fiskeby III and Mandarin (Ottawa) genotypes was not explained by differences in the antioxidant enzymes and metabolites tested. Ethylene emission from leaves declined in Fiskeby III following O3 exposure but was not altered in Mandarin (Ottawa). Ozone exposure reduced quantum yield (ΦPSII ), electron transport rate (ETR) and photochemical quenching (qp ) in Mandarin (Ottawa) more than in Fiskeby III, indicating that the efficiency of energy conversion of PSII and photosynthetic electron transport was altered differently in the two genotypes. Short-term exposure to O3 had minimal effects on net carbon exchange rates of both soybean cultivars. A trend toward higher leaf stomatal conductance in Mandarin (Ottawa) suggested stomatal exclusion may contribute to the differential O3 sensitivity of the two genotypes. In conclusion, increased sensitivity of Mandarin (Ottawa) to O3 was associated with greater hydrogen peroxide and superoxide production compared with Fiskeby III, possibly associated with genotype differences in stomatal function or the regulation of ethylene during the initial phases of O3 response.
