    ABSTRACT: The transition zone between terrestrial and freshwater habitats is highly dynamic with large variability in environmental characteristics. Here, we investigate how these characteristics influence the nutritional status and performance of plant life forms inhabiting this zone. Specifically, we hypothesized 1) that tissue nutrient contents differ among submerged, amphibious, and terrestrial species, with higher contents in submerged species, and 2) that the photosynthetic nutrient use efficiency gradually increases from submerged over amphibious to terrestrial species, reflecting differences in the availability of N and P relative to inorganic carbon across the land-water ecotone. We found that tissue nutrient contents were generally higher in submerged species and also that C:N and C:P ratios indicated that contents were limiting for growth for app. 20% of the plant individuals, in particular those belonging to the amphibious and terrestrial species groups. As predicted, we found that the photosynthetic nutrient use efficiency increased from submerged over amphibious to terrestrial species. We suggest that this pattern reflects that amphibious and terrestrial species allocate proportionally more nutrients into processes of importance for photosynthesis at saturating CO2 availability, i.e. enzymes involved in substrate regeneration compared to submerged species that are acclimated to lower availability of CO2 in the aquatic environment. In conclusion, our results indicate that enhanced nutrient loading may affect the relative abundance of the three species groups in the land-water ecotone of stream ecosystems. Thus species belonging to the amphibious and terrestrial species groups are likely to benefit more from enhanced nutrient availability in terms of faster growth compared to aquatic species and also that this can be to the detriment of aquatic species growing in the land-water ecotone, like for instance Ranunculus and Callitriche.

    ABSTRACT: We measured leaf photosynthetic traits in shade-grown seedlings of four tree species native to northern Japan raised under an elevated CO2 condition to investigate the effects of elevated CO2 on shade tolerance of deciduous broadleaf tree species with different successional traits. We considered Betula platyphylla var. japonica and Betula maximowicziana as pioneer species, Quercus mongolica var. crispula as a mid-successional species, and Acer mono as a climax species. The plants were grown under a shade condition (10% of full sunlight) in a CO2 -regulated phytotron. Light compensation points (LCPs) decreased in all tree species when they were grown under elevated CO2 (720 μmol mol(-1) ), which were accompanied by higher apparent quantum yields but no photosynthetic downregulation. LCPs in Q. mongolica and A. mono grown under elevated CO2 were lower than those in the two pioneer birch species. The LCP in Q. mongolica seedlings was not different from that of A. mono in each CO2 treatment. However, lower dark respiration rates were observed in A. mono than those in Q. mongolica, suggesting greater shade tolerance in A. mono as a climax species in relation to carbon loss during nighttime. Thus, elevated CO2 may have enhanced shade tolerance by lowering the LCPs in all species but the ranking of shade tolerance related to successional traits did not change among species under elevated CO2 , i.e., the highest shade tolerance was observed in the climax species (A. mono), followed by a gap-dependent species (Q. mongolica), and lower shade tolerance was observed in the pioneer species (B. platyphylla and B. maximowicziana).

    ABSTRACT: Oncidium 'Gower Ramsey' (Onc. GR) is a popular cut flower, but its color is limited to bright yellow. The β-ring carotene hydroxylase (BCH2) gene is involved in carotenoid biogenesis for pigment formation. However, the role of BCH2 in Onc. GR is poorly understood. Here, we investigated the functions of three BCH2 genes, BCH-A2, BCH-B2, and BCH-C2, isolated from Onc. GR to analyze their roles in flower color. RT-PCR expression profiling suggested that BCH2 genes were mainly expressed in flowers. The expression of BCH-B2 remained constant while that of BCH-A2 gradually decreased during flower development. Using Agrobacterium tumefaciens to introduce BCH2 RNA interference (RNAi), we created transgenic Oncidium plants with downregulated BCH expression. In the transgenic plants, flower color changed from the bright yellow of the wild type to light- and white-yellow. BCH-A2 and BCH-B2 expression levels were significantly reduced in the transgenic flower lips, which make up the major portion of Oncidium flower. Sectional magnification of the flower lip showed that the amount of pigmentation in the papillate cells of the adaxial epidermis was proportional to the intensity of yellow coloration. HPLC analyses of the carotenoid composition of the transgenic flowers suggested the major reductions in neoxanthin and violaxanthin pigments. Conclusively, BCH2 expression regulated the accumulation of yellow pigments in Oncidium flower, and the down regulation of BCH-A2 and BCH-B2 changed the flower color from bright yellow to light- and white-yellow.

    ABSTRACT: Enhanced soil ammonium (NH4 (+) ) concentrations in wetlands often leads to graminoid dominance, but species composition largely varies. Although NH4 (+) is readily taken up as a nutrient, several wetland species are known to be sensitive to high NH4 (+) concentrations or even suffer from toxicity, particularly at low soil pH. More knowledge about differential graminoid responses to high NH4 (+) availability in relation to soil pH can help to better understand vegetation changes. The responses of two wetland graminoids, Juncus acutiflorus and Carex disticha, to high (2 mmol L(-1) ) versus control (20 μmol L(-1) ) NH4 (+) concentrations were therefore tested in a controlled hydroponic set up, at two pH values (4 and 6). A high NH4 (+) concentration did not change total biomass for both species at either pH, but increased carbon allocation to the shoots, increased P uptake, and led to K and Ca limitation, depending on pH treatment. More than 50% of N taken up by C. disticha was invested in N-rich amino acids with a decreasing C:N ratio, while this was only 10% for J. acutiflorus. Although both species appeared to be well adapted to high NH4 (+) loadings in the short term, C. disticha showed a higher extent of classic detoxifying responses that are early warning indicators for decreased tolerance in the long term. In general, the efficient above-ground biomass allocation, P-uptake, and N detoxification explain the competitive strength of wetland graminoids at the expense of overall biodiversity at high NH4 (+) loadings. In addition, differential responses to enhanced NH4 (+) affect interspecific competition among graminoids and lead to a shift in vegetation composition. This article is protected by copyright.

    ABSTRACT: Depending on their specificity to gypsum, plants can be classified as gypsophiles (gypsum exclusive) and gypsovags (non-exclusive). The former may further be segregated into wide and narrow gypsophiles, depending on the breadth of their distribution area. Narrow gypsum endemics have a putative similar chemical composition to plants non-exclusive to gypsum (i.e. gypsovags), which may be indicative of their similar ecological strategy as stress tolerant plants refugees on gypsum. However, this hypothesis awaits testing in different regions of the world. We compared the chemical composition of four narrow gypsum endemics, one widely distributed gypsophile and six gypsovags from Turkey. Further, we explored the plasticity in the chemical composition of Turkish gypsovags growing on high- and low-gypsum content soils. Differences were explored by multivariate analyses (RDA) and mixed models (REML). Narrow gypsum endemics segregated from gypsovags due to their chemical composition according to RDAs (mainly due to a higher K and ash content in the former). Nevertheless, differences were small and disappeared when different nutrients were analysed individually. All the gypsovags studied accumulated more S and ash when growing on high-gypsum than on low-gypsum soils. Similar to narrow gypsum endemics from other regions of the world, most local gypsum endemics from Turkey show a similar chemical composition to gypsovags. This may indicate a shared ecological strategy as stress tolerant plants not specifically adapted to gypsum. Nevertheless, the narrow gypsum endemic Gypsophila parva showed a chemical composition typical of gypsum specialists, indicating that various strategies are feasible within narrowly distributed gypsophiles.

    ABSTRACT: Rising atmospheric CO2 concentrations (e[CO2 ]) are presumed to have a significant impact on plant growth and yield and also on mineral nutrient composition, and therefore on nutritional quality of crops and vegetables. To assess the relevance of these effects in future agroecosystems it is important to understand how e[CO2 ] interacts with other environmental factors. In the present study we examined the interactive effects of e[CO2 ] with temperature and the form in which nitrogen is supplied (nitrate or ammonium nitrate) on growth, amino acid content and mineral nutrient composition of Chinese cabbage (Brassica pekinensis Rupr.), a crop characterized by its high nutritional value and increasing relevance for human nutrition in many developing countries. Higher temperature, ammonium nitrate and e[CO2 ] had a positive impact on net photosynthesis and growth. A stimulating effect of e[CO2 ] on growth was only observed if the temperature was high (21/18°C, day/night), and an interaction of e[CO2 ] with N form was only observed if the temperature was ambient (15/12°C, day/night). Mineral nutrient composition was affected in a complex manner by all three factors and their interaction. These results demonstrate how much the effect of e[CO2 ] on mineral quality of crops depends on other environmental factors. Changes in temperature, adapting N fertilization and the oxidation state of N have the potential to counteract the mineral depletion caused by e[CO2 ]. This article is protected by copyright.

    ABSTRACT: We studied highly abundant chromoviral Tekay clade in species from three sister genera - Anemone, Pulsatilla and Hepatica of the Ranunculaceae family. With this clade we performed a concomitant survey of its phylogenetic diversity, chromosomal organization and transcriptional activity in Anemone s.l. in order to investigate the dynamics of the Tekay elements at a finer scale than previously achieved in this or any other flowering clade. A phylogenetic tree built from Tekay sequences does conform to expected evolutionary relationships of the species. Only exceptions are A. nemorosa and A. sylvestris, which appeared more closely related that expected and we invoke the hybridization events to explain the observed topology. The separation of the elements within six clusters could be explained by episodic bursts of activity since divergence from a common ancestor, at different points in their respective evolutionary histories. In Anemone s.l. the Tekay elements do not have preferential position on chromosomes, meaning that they can have: i) centromeric/pericentromeric position; ii) interstitial position in DAPI positive AT-rich heterochromatic regions; or they can be iii) dispersed throughout chromosomes or even iv) absent from large heterochromatic blocks. Widespread transcriptional activity of the Tekay elements in Anemone s.l. taxa indicate that some copies of Tekay elements could be still active in this plant group contributing to the genome evolution and speciation within the Anemone s.l. Identification of the Tekay elements in Anemone s.l. provides a valuable entry into an understanding how different localization patterns might help to facilitate plant genome organization in a structural and functional manner.

    ABSTRACT: It is generally accepted that the genus Magnolia is characterized by an undifferentiated perianth, typically organized into the three whorls of nearly identical tepals. In some species, however, we encountered interesting and significant perianth modifications. In Magnolia acuminata, M.liliiflora and M.stellata, the perianth elements of the first whorl are visually different from the others. In Magnolia stellata the additional, spirally arranged perianth elements are present above the first three whorls, which suggests that they have been formed within the domain of stamen primordia. In these three species we analysed the expression patterns of the key flower genes (AP1, AGL6, AP3, PI, AG) responsible for the identity of flower elements and we correlated them with the results of morphological and anatomical investigation. In all studied species the elements of the first whorl lacked the identity of petals (lack of AP3 and PI expression) but also that of the leaves (presence of AGL6 expression) and this seems to prove their sepal character. The analysis of additional perianth elements of M.stellata, spirally arranged on the elongated floral axis, revealed overlapping and fading activity of genes involved in specification of the identity of the perianth (AGL6) but also of generative parts (AG), even though no clear gradient of morphological changes could be observed. In conclusion, Magnolia genus is capable of forming, in some species, a perianth differentiated into a calyx (sepals) and corolla (petals). Spirally arranged, additional perianth elements of M.stellata, despite the activity of AG fading basipetally, resemble petals. This article is protected by copyright. All rights reserved.

    ABSTRACT: Temperature is one of the key factors in limiting the distribution of plants and controlling major metabolic processes. A series of simulated reciprocal transplant experiments were performed to investigate the effect of temperature on plant chemical composition. Polygonum minus from different lowland and highland origins were grown under controlled environment with different temperature regimes to study the effects on secondary metabolites. We applied gas chromatography-mass spectrometry and liquid chromatography time-of-flight mass spectrometry to identify the chemical compounds. A total of 37 volatile organic compounds and 85 flavonoids were detected, with the greatest response observed in the compositional changes of aldehydes and terpenes in highland plants under higher temperature treatment. Significantly less anthocyanidin compounds and greater amounts of flavonols were detected under higher temperature treatment. We also studied the natural variation in the different plant populations growing under the same environment and identified compounds unique to each population through metabolite fingerprinting. This study shows that the origin of different plant populations influences the effects of temperature on chemical composition.This article is protected by copyright. All rights reserved.

    ABSTRACT: The atmospheric vapor pressure deficit (vpd) is the driving force for plant transpiration. Plants have different strategies to respond to this ‘atmospheric drought.’ Deposited aerosols on the surface of plant leaves can interact with plant water relations and may influence the vpd response of plants. We studied the transpiration and water use efficiency of pine, beech, and sunflower plants by measuring the sap flow, gas exchange, and carbon isotopes, thereby addressing different timescales of plant/atmosphere interaction. Plants were grown i) outdoors under rainfall exclusion by a shelter (OD) and in ventilated greenhouses with either ii) ambient air (AA) or iii) filtered air (FA), the latter containing less than 1% ambient aerosol concentrations. In addition, some AA plants were sprayed once with a 25 mN salt solution of either ammonium sulfate or sodium nitrate.The carbon isotope values (δ13C) became more negative in the presence of more particles. They were more negative for AA sunflower compared to FA sunflower and were more negative for OD Scots pine seedlings compared to the other growth environments. FA beech seedlings had less negative δ13 C values than AA, OD, and NaNO3-treated beech seedlings. The anisohydric beech seedlings showed linearly increasing sap flow with increasing vpd. The slopes doubled for (NH4)2SO4-and tripled for NaNO3-sprayed beech seedlings compared to control seedlings, indicating a decreased ability to resist the atmospheric demand. In contrast, the isohydric pine seedlings showed constant transpiration rates with increasing vpd, independent of the growth environment and spray, which was likely caused by decreasing stomatal conductance with increasing vpd. Generally, NaNO3 spray caused stronger effects on the water relations than (NH4)2SO4 spray. The results strongly support the role of leaf surface particles as an environmental factor affecting plant water use. The hygroscopic and chaotropic properties of leaf surface particles determine their ability to form wicks across the stomata. Such wicks enhance the unproductive water loss of anisohydric plant species and decrease the CO2 uptake of isohydric plant species. They become more relevant with increasing numbers of fine particles and increasing vpd and are thus related to air pollution and climate change. Wicks cause a deviation from the analogy between CO2 and water pathways through the stomata, bringing some principal assumptions of gas exchange theory into question.This article is protected by copyright.

    ABSTRACT: The low resolution of chromosome-based FISH mapping is primarily due to the structure of the plant cell wall and cytoplasm and the compactness of regular chromosomes that represent a significant obstacle to FISH. In order to improve spatial resolution and signal detection sensitivity, we provide a reproducible method to generate high-quality extended chromosomes which are ~13 times as long as their pachytene counterparts. We demonstrate that proteinase K used in this procedure is crucial for stretching pachytene chromosomes of Brassica oleracea in the context of a modified Carnoy's II fixative (6:1:3 ethanol:chloroform:acetic acid). The quality of super-stretched chromosomes was assessed in several FISH experiments. FISH signals from both repetitive 5S rDNA and single-copy ARC1 on super-stretched chromosomes are brighter than those on other different types of chromosomes, due to enhanced accessibility to targets on stretched pachytene chromosomes. In conclusion, the resulting extended chromosomes are suitable for FISH mapping for repetitive DNA sequences, and the localization of a single-copy locus, and FISH performed on super-stretched chromosomes can achieve a significantly higher sensitivity and spatial resolution than other chromosome-based FISH mapping techniques.

    ABSTRACT: Environmentally inducible phenotypic plasticity is a major player in plant responses to climate change. However, metabolic responses and their role in determining the phenotypic plasticity of plants that are subjected to temperature variations remain poorly understood. The metabolomic profiles and metabolite levels in the leaves of three maize inbred lines grown in different temperature conditions were examined with a nuclear magnetic resonance metabolomic technique. The relationship of functional traits to metabolome profiles and the metabolic mechanism underlying temperature variations were then explored. A comparative analysis showed that during heat and cold stress, maize plants shared common plastic responses in biomass accumulation, carbon, nitrogen, sugars, some amino acids and compatible solutes. We also found that the plastic response of maize plants to heat stress was different from that under cold stress, mainly involving biomass allocation, shikimate and its aromatic amino acid derivatives, and other non-polar metabolites. The plastic responsiveness of functional traits of maize lines to temperature variations was low, while the metabolic responsiveness in plasticity was high, indicating that functional and metabolic plasticity may play different roles in maize plant adaptation to temperature variations. A linear regression analysis revealed that the maize lines could adapt to growth temperature variations through the interrelation of plastic responses in the metabolomes and functional traits, such as biomass allocation and the statuses of carbon and nitrogen. We provide valuable insight into the plastic response strategy of maize plants to temperature variations that will permit the optimization of crop cultivation in an increasingly variable environment.

    ABSTRACT: Common bean (Phaseolus vulgaris L., Fabaceae) is a globally important staple crop, which is an important source of calories, protein and essential micronutrients. At the genomic level little is known regarding the small non-coding RNAs within the common bean genome. One of the most important classes of such small non-coding RNAs are microRNAs (miRNAs) which control mRNA and protein expression levels in many eukaryotes. Computational methods have been applied to identify putative miRNAs in the genomes of different organisms. In this study, our objective was to comprehensively identify and characterize miRNAs from the genome and transcriptome of P. vulgaris, including both mature and precursor miRNA forms. We also sought to identify the putative proteins involved in miRNA processing and the likely target genes of common bean miRNAs. We identified 221 mature miRNAs and 136 precursor miRNAs distributed across 52 different miRNA families in the P. vulgaris genome. Amongst these, we distinguished 129 novel mature miRNAs and 123 miRNA precursors belonging to 24 different miRNA families. We also identified 31 proteins predicted to participate in the miRNA processing pathway in P. vulgaris. Finally, we also identified 483 predicted miRNA targets including many which corroborate with results from other species, suggesting that miRNA regulatory systems are evolutionarily conserved and important for plant development. Our results expand the study of miRNAs and their target genes in common bean, and provide new opportunities to understand their roles in the biology of this important staple crop.

    ABSTRACT: Plant peroxisomes are unusual subcellular compartments with an apparent simple morphology but with a complex metabolic activity. The presence of signal molecules, such as hydrogen peroxide (H2 O2 ) and nitric oxide (NO) inside plant peroxisomes have added new functions in the cross-talk events among organelles and cells under physiological and stress conditions. Moreover, recent advances in proteomic analyses of plant peroxisomes have identified new protein candidates involved in several novels metabolic pathways. With all these new data, the present concise manuscript will put the focus in the relevance of the peroxisomal H2 O2 and its two main antioxidant enzymes, catalase and membrane-bound ascorbate peroxidase (pAPX), which regulate its level and consequently its potential functions.

    ABSTRACT: Programmed cell death (PCD) is an essential part of the ontogeny of roots and their tolerance/resistance mechanisms, allowing adaptation and growth under adverse conditions. It occurs not only at the cellular and sub-cellular level, but also at the levels of tissues, organs and even whole plants. This process involves a wide spectrum of mechanisms, from signalling and the expression of specific genes to the degradation of cellular structures. The major goals of this review were to broaden current knowledge about PCD processes in roots, and to identify mechanisms associated with both developmental and stress-associated cell death in roots. Vacuolar cell death, when cell contents are removed by a combination of an autophagy-associated process and the release of hydrolases from a collapsed vacuole, is responsible for programming self-destruction. Regardless of the conditions and factors inducing PCD, its subcellular events usually include the accumulation of autophagosome-like structures, and the formation of massive lytic compartments. In some cases they are followed by the nuclear changes of chromatin condensation and DNA fragmentation. Tonoplast disruption and vacuole implosion occur very rapidly, are irreversible, and constitute a definitive step toward cell death in roots. Active cell elimination plays an important role in various biological processes in the life history of plants, leading to controlled cellular death during adaptation to changing environmental conditions, and organ remodelling throughout development and senescence.
