    ABSTRACT: The chenopod Beta macrocarpa Guss (wild Swiss chard) is known for its salt tolerance, but the mechanisms involved are still debated. In order to elucidate the processes involved, we grew wild Swiss chard exposed to three salinity levels (0, 100 and 200 mM NaCl) for 45 days, and determined several physiological parameters at the end of this time. All plants survived despite the reductions in growth, photosynthesis and stomatal conductance in plants exposed to salinity (100 and 200 mM NaCl). As expected, the negative effects of salinity were more pronounced at 200 mM than at 100 mM NaCl: 1) leaf apoplastic water content was maintained or increased despite a significant reduction in leaf water potential, revealing the halophytic character of B. macrocarpa; 2) osmotic adjustment (OA) occurred, which presumably enhanced the driving force for water extraction from soil, and avoided toxic buildup of Na(+) and Cl(-) in the mesophyll apoplast of leaves. OA mainly occurred by the accumulation of inorganic ions and to a lesser degree soluble sugars; proline was not implicated in OA. Overall, two important mechanisms of salt tolerance of B. macrocarpa were identified: osmotic and apoplastic water adjustment. This article is protected by copyright. All rights reserved.

    ABSTRACT: The Cellulose Synthase (CESA) gene family of seed plants comprises six clades that encode isoforms with conserved expression patterns and distinct functions in cellulose synthesis complex (CSC) formation and primary and secondary cell wall synthesis. In mosses, which have rosette CSCs like those of seed plants but lack lignified secondary cell walls, the CESA gene family diversified independently and includes no members of the six functionally distinct seed plant clades. There are seven CESA isoforms encoded in the genome of the moss Physcomitrella patens. However, only PpCESA5 has been characterized functionally and little information is available on the expression of other PpCESA family members. We have profiled PpCESA expression through quantitative RT-PCR, analysis of promoter-reporter lines, and cluster analysis of public microarray data in an effort to identify expression and co-expression patterns that could help reveal the functions of PpCESA isoforms in protein complex formation and development of specific tissues. In contrast to the tissue-specific expression observed for seed plant CESAs, each of the PpCESAs was broadly expressed throughout most developing tissues. Although a few statistically significant differences in expression of PpCESAs were noted when some tissues and hormonal treatments were compared, no strong co-expression patterns were observed. Along with CESA phylogenies and lack of single PpCESA mutant phenotypes reported elsewhere, broad overlapping expression of the PpCESAs indicates a high degree of interchangeability and is consistent with a different pattern of functional specialization in the evolution of the seed plant and moss CESA families.

    ABSTRACT: The objective of this work was to ascertain whether there is a general pattern of carbon allocation and utilization in plants following herbicide supply, independent of the site of application: sprayed on the leaves or supplied to the nutrient solution. The herbicides studied were the amino acid biosynthesis-inhibiting herbicides (ABIH): glyphosate, an inhibitor of aromatic amino acid biosynthesis, and imazamox, an inhibitor of branched-chain amino acid biosynthesis. All treated plants showed impaired carbon metabolism. Carbohydrate accumulation was detected in both the leaves and roots of the treated plants. The accumulation in the roots was due to a lack of utilization of available sugars as growth was arrested, which elicited soluble carbohydrate accumulation in the leaves due to a decrease in sink strength. Under aerobic conditions, the ethanol fermentative metabolism was enhanced in the roots of the treated plants. This fermentative response was not related to a change in the total respiratory rates or cytochrome respiratory capacity, but an increase in the alternative oxidase capacity was detected. Pyruvate accumulation was detected after most of the herbicide treatments. These results demonstrate that both ABIH induce the less-efficient ATP-producing pathways, namely fermentation and alternative respiration, probably by increasing the key metabolite pyruvate. The plant response was similar not only for the two ABIH but also after foliar or residual applications. This article is protected by copyright. All rights reserved.

    ABSTRACT: Background and aims: Herbaceous species can modify leaf structure during the growing season in order to respond to drought stress and reduce water loss. Evolutionary processes can select combinations of traits in plants for efficient water use in restricted environments. This study investigated plant traits that mediate the adaptation and acclimation to water stress in two herbaceous drought tolerant species. Methods: Several anatomical, morphological and physiological traits related to stems and leaves were examined under optimal watering (OW) and a long period of restricted watering (RW) conditions in 11 accessions from three species of the Solanaceae family (Solanum chilense, S. peruvianum and S. lycopersicum). The relationships between these traits were tested using linear regression and principal component analysis. Key results: Significant differences were found for anatomical traits between the three species under both OW and RW treatments, where leaf area (LA) correlated with stem diameter (StemD). Proline and total carbohydrates (TC) accumulated highly in S. chilense and S. peruvianum, respectively, and these osmolytes were strongly correlated with increase of osmotic potential (Ψπ). The stomatal density (SD) varied between species but not between acclimation treatments, while the stomatal rate (SR) was significantly higher in wild tomatoes. The tomato species exhibited a strong positive relationship between stem growth rate (SGR) and a group of traits together expressed as total stomatal number (TSt). TSt was described in this research by the integration of LA, SD, Height (H) and internode length (IntL). Conclusions: It is proposed that constitutive adaptations as well as modifications by acclimation that mediate RW treatment plays an important role in tolerance to drought stress in herbaceous plants. The capacity of growth under drought stress was not associated with any single combination of traits in wild tomatoes, since the two species differed in relative levels of expression of various phenotypical traits.

    ABSTRACT: With a distribution range that covers most of the northern hemisphere, common juniper (Juniperus communis) has one of the largest ranges of all vascular plant species. In several regions in Europe, however, populations are decreasing in size and number due to failing recruitment. One of the main causes for this failure is low seed viability. Observational evidence suggests that this is partly induced by climate warming but our mechanistic understanding of this effect remains incomplete. Here we experimentally assess the influence of temperature on two key developmental phases during the sexual reproduction, i.e. gametogenesis and fertilization (seed phase two, SP2) and embryo development (seed phase three, SP3). Along a latitudinal gradient from southern France to central Sweden, we installed a transplant experiment with shrubs originating from Belgium, a region with unusually low juniper seed viability. Seeds of both seed phases were sampled during three consecutive years, and seed viability assessed. Warming temperatures negatively affected the seed viability of both SP2 and SP3-seeds along the latitudinal gradient. Interestingly, the effect on embryo development (SP3) only occurred in the third year, i.e., when the gametogenesis and fertilization also took place in warmer conditions. We found strong indications that this negative influence mostly acts via disrupting the growth of the pollen tube, the development of the female gametophyte and the fertilization (SP2). This, in turn, can lead to a failing embryo development, for example, due to nutritional problems. Our results stress that climate warming can indeed negatively affect seed viability of juniper.

    ABSTRACT: In the last decade, genetic and pharmacological approaches have been used to explore ethylene biosynthesis and perception in order to study the role of ethylene and ethylene/auxin interaction in root architecture development. However, recent findings with pharmacological approaches highlight the non-specificity of commonly used inhibitors. This suggests that caution is required for interpreting these studies and that the use of pharmacological agents is a “double edged” tool. On one hand, non-specific effects make interpretation difficult unless other experiments, such as with different mutants or with multiple diversely acting chemicals, are conducted. On the other hand, the non-specificity of inhibitors opens up the possibility of uncovering some ligands or modulators of new receptors such as plant glutamate-like receptors and importance of some metabolic hubs in carbon and nitrogen metabolism involved in the regulation of the root morphogenetic program. Identification of such targets is a critical issue to improve the efficiency of absorption of macronutrients in relation with root morphogenetic program.

    ABSTRACT: A plant's compensatory performance refers to its ability to maintain or increase its reproductive output following damage. The ability of a plant to compensate depends on numerous factors including the type, severity, frequency, and timing of damage, the environmental conditions, and the plant's genotype. Upon apical damage, a cascade of hormonal and genetic responses often produces dramatic changes in a plant's growth, development, architecture, and physiology. All else being equal, this response is largely dependent on a plant's genotype with different regrowth patterns displayed by different genotypes of a given species. In this study, we compare the architectural and growth patterns of two Arabidopsis thaliana genotypes following apical damage. Specifically, we characterize regrowth patterns of the genotypes Columbia-4 and Landsberg erecta, which typically differ in their compensation to apical meristem removal. We report that Landsberg erecta suffered reductions in the number of stems produced, their maximum elongation rate, a delay in reaching this rate, lower average rosette quality throughout the growing period, and ultimately less above-ground dry biomass and seed production when damaged compared to undamaged control plants. Columbia-4 had no reductions in any of these measures and maintained greater rosette area when clipped relative to when unclipped. Based on the apparent influence of the rosette on these genotypes' compensatory performances, we performed a rosette removal experiment which confirmed that the rosette contributes to compensatory performance. This study provides a novel characterization of regrowth patterns following apical damage with insights into those measures having the greatest effect on plant performance.

    ABSTRACT: The effect that epiphytes have on their hosts has been poorly explored in an experimental sense. Correlational evidence suggests that epiphytes may be either mutualists or structural parasites, as has been proposed for Tillandsia recurvata on Parkinsonia praecox. To test the effect of T. recurvata upon P. praecox, the epiphyte load on branches of P. praecox was measured and two one-year experiments were performed to detect the effect of transplantation/removal of epiphytes and shade (0%, 35%. 50% and 80%) on shoot dynamics. If T. recurvata represents a selective pressure for P. praecox, then the frequency of branches carrying large epiphyte loads will be high, and host shoot survival will decrease in the presence of T. recurvata, and with increased shade. A weak inverse relationship between epiphyte load and percentage of dead shoots in the host was detected. Shoot survival was independent of epiphyte presence. Shade decreased between 35-72% shoot survival. Results suggest that at the study site, T. recurvata is a commensalist of Parkinsonia praecox. An alternative hypothesis to explain the correlation between high epiphyte load and branch/tree decay is that older branches carry more epiphytes, receive more shade from neighbouring branches and could be undergoing a natural decline process.This article is protected by copyright.

    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: 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: 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: 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.
