It is noteworthy, however, that genotypes responded differently to the varying salinity levels. Search. various components of vegetation, such as old‐growth trees, natural regeneration and understorey species, mycorrhizal fungi, free‐living fungi and bacteria. Not logged in This review updates the current knowledge on MDH isoforms and the shuttle systems for intercompartmental dicarboxylate exchange, focusing on the various metabolic functions of these valves. By the year 2100, temperatures are predicted to increase by about 6 °C at higher latitudes and about 3 °C in the tropics. The Journal of Plant Biology is an official publication of the Korean Society of Plant Biologists. While increased atmospheric CO2 concentration over the past 150 years has been accompanied by greater CO2 assimilation and storage in terrestrial ecosystems, there is evidence that rising temperatures and increased drought stress may limit the ability of future terrestrial ecosystems to buffer against atmospheric emissions. Please read more details. We found evidence for isolation‐by‐distance, but overall differentiation of the populations was rather weak. Additionally, we highlight the current methodological difficulties that limit present understanding of N cycling in forest ecosystems and the need for interdisciplinary studies. Search. In spite of the smaller increase in the tropics, consequences may be more severe because the climatic niches of tropical species are generally assumed to be rather narrow due to a high degree of climate stability and higher niche specialisation. Agricultural propagation of native seed material for restoration can cause evolutionary changes, at least in some species. Securing and augmenting agricultural yield in times of global warming and population increase is urgent and should, aside from ameliorating saline soils, include attempts to increase crop plant salt tolerance. The concentration of fructose and fructan, as well as amounts per area of total and individual non‐structural carbohydrates, except for starch, significantly increased in the grain. All original research papers, case reports, topical reviews and meeting reports relate to plant biology are encouraged to publish in this journal. Thus, flowers of. The impact of anther morphology on pollen release direction and scattering angle was studied to determine the plant's reproductive strategy. and you may need to create a new Wiley Online Library account. In contrast, the plastid NAD‐MDH (‘dark malate valve’) is constitutively active and its lack leads to failure in early embryo development. The interlink of the physiological understanding of tolerance processes from molecular processes as well as the agronomical techniques for stabilizing growth and yield and their interlinks might help improving our crops for future demand and will provide improvement for cultivating crops in saline environment. As a result of the significant disruption that is being caused by the COVID-19 pandemic we are very aware that many researchers will have difficulty in meeting the timelines associated with our peer review process during normal times. Volume 63 February - December 2020. This is especially pronounced for C3 plants, at high temperatures and under water‐limited conditions. Deadline: 31 May 2021 (full article submission) Females dominated 11 populations, which overall resulted in a slightly female‐biased sex ratio (61.5%). This approach allows selection of desirable genotypes at early growth stages, thus enabling more efficient application of various breeding methods to achieve stress‐tolerant lentil genotypes. Journal updates Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our … Evidence for degradation of stromal proteins outside of chloroplasts is summarised. Salinity stress was applied by addition of NaCl at three different levels of stress, while non‐stressed plants were included as controls. If restoration of degraded native grassland is to be achieved at the scale now required, cost‐effective means for seed‐based establishment of grass species is crucial. (ii) In mixture, spruce and oak perform as in pure stands, but beech was significantly more resistant and resilient than in monoculture. The high genetic diversity and low genetic differentiation suggest that. Journal updates Tropical Plant Biology covers rapidly advancing aspects of tropical plant biology including physiology, evolution, development, cellular and molecular biology, genetics, genomics, genomic ecology, and molecular breeding. Here, we used quantitative real‐time polymerase chain reaction (qRT‐PCR) analysis to study the expression of 1880 TF genes during pre‐senescence and early‐senescence stages of leaf development, using Arabidopsis thaliana as a model. Senescence is not observed in young leaves, indicating that repressors efficiently act to suppress cell degradation during early leaf development and/or that senescence activators are switched on when a leaf ages. A number of these pollutants have direct effects on plants, including carbon dioxide (CO2), which is the substrate for photosynthesis, and ozone (O3), a damaging oxidant. Total grain protein concentration decreased significantly by 7.4% under elevated CO2, and protein and amino acid composition were altered. Although the propagation methods are usually designed to maintain as much natural genetic diversity as possible, the effectiveness of these measures have never been tested. American Journal of Plant Biology (AJPB) is an open access, online international journal. Working off-campus? To meet this demand, seeds are often produced through large‐scale cultivation on specialised farms, using wild‐collected seeds as the original sources. Plant Biology is now inviting submissions for an upcoming Special Issue: Emerging Roles of Hydrogen Sulfide as a Signaling Molecule in Plant Biology Please read more details here. Stamens are often dimorphic, sometimes with discernible feeding and pollinating functions. Rubisco is thought to be released from chloroplasts into vesicles containing stroma material (RCB = Rubisco‐containing bodies). Despite its destructive character, senescence is a precisely controlled process that follows a well‐defined order. The genetic material consisted of six lentil genotypes whose adaptation to various agroclimatic conditions is not well elucidated. Intriguingly, however, we find that the upper (adaxial) flower surface that surrounds the reproductive organs and often constitutes the floral display is markedly more structured than the lower (abaxial) surface. Floral micro‐texture can provide tactile cues to insects, and increases in surface roughness by means of conical (papillose) epidermal cells may facilitate flower handling by landing insect pollinators. This is likely to increase photosynthetic carbon gain in nutrient‐limited systems. Resulting from the ventral and dorsal positioning of the short and long stamens, respectively, the pollinator's body was widely covered with pollen. In degraded dryland systems, native plant community re‐establishment following disturbance is almost exclusively carried out using seeds, but these efforts commonly fail. Auxins and carbohydrates have been assigned a dual role in the regulation of senescence, and can both inhibit and stimulate the senescence process. The seed processing methods developed and tested in the present study can be applied to grass species that present similar handling and germination performance impediments. Among 234 SCI-indexed Plant Science journals in the world, JIPB ranks 17th (top 7.3%, Q1 category). The role of stomatal physiology is emphasised, as it controls most of these processes. This journal covers a full range of biochemistry, cellular biology, development, ecology, genetics, molecular biology, physiology, and systematics of plants. The epidermal cells of flowers come in different shapes and have different functions, but how they evolved remains largely unknown. December 2020, issue 6; October 2020, issue 5; Journal of Plant Biology, Chemistry and Ecophysiology is an online, peer-reviewed open access journal including various fields of science and medicine with intent to bridge the gap between academia and research access mainly devoted to basic researches in biochemistry, cellular biology, development, ecology, genetics, molecular biology, physiology, and systematics of plants. Journal of Plant Biology and Agriculture Science is an international circulating peer-reviewed Open Access journal, provides limitless access to our literature hub presenting original research contributions and scientific advances in the field of Agriculture and Plant Biology. The largest proportion (62%) exhibited physiological (PD), followed by physical (PY, 8%), combinational (PY + PD, 8%) and morphophysiological (MPD, 4%) dormancy classes. Journal of Soil and Plant Biology is an international scholarly journal which publishes papers on an open access platform and follows strict double-blind peer review process. Long‐term Free Air CO2 or O3 Enrichment (FACE) experiments provide critical experimentation about the effects of future CO2 and O3 on ecosystems, and highlight the important interactive effects of temperature, nutrients and water supply in determining ecosystem responses to air pollution. In this paper, we analyse three successful community‐based networks that supply native seeds and seedlings for Brazilian Amazon and Cerrado restoration projects. We discuss the far‐reaching implications that these differences in stress response under intra‐ and inter‐specific environments have for forest ecosystem dynamics and management under climate change. It can be cointegrated with other omics like functional genomics, transcriptomics, and metabolomics etc. Large‐scale restoration programmes in the tropics require large volumes of high quality, genetically diverse and locally adapted seeds from a large number of species. Please do let us know if you need additional time. Much of this failure can be attributed to the limited understanding of seed dormancy and germination traits. Long‐term experimentation in both natural and cropping systems is needed to provide critical empirical data for modelling the effects of air pollutants on plant productivity in the decades to come. This improves the plant's chances of outcrossing, irrespective of which bee body part contacts the stigma. There was no significant relationship between population size and genetic diversity. Such breeding has to cope with the dilemma that delayed senescence, which could lead to higher yields, is correlated with a decrease in nutrient use efficiency. Thus, massive regulatory network re‐wiring likely constitutes an important component of the pre‐senescence process. The NADP‐MDH as part of the ‘light malate valve’ plays an important role as a poising mechanism to adjust the ATP/NADPH ratio in the stroma. Senescence may occur naturally because of age or may be induced by various endogenous and exogenous factors. We show that the expression of 185 TF genes changes when leaves develop from half to fully expanded leaves and finally enter partial senescence. (i) In pure stands, spruce has the lowest resistance, but the quickest recovery; oak and beech were more resistant, but recover was much slower and they are less resilient. The Journal of plant biology and crop research deals in various research findings in the various areas of plant biology like the genetics and breeding, molecular physiology, genomics and molecular genetics, ecosystem biogeochemistry, marine ecology, terrestrial ecology, biological modelling, pathology, weed science and crop production agronomy. This short review provides an overview of the processes that limit growth and yield in saline conditions. Evaluation of tolerance was performed on the basis of germination percentage, seed water absorbance, root and shoot length, seedling water content, seedling vigour index and number of seedlings with an abnormal phenotype. Planta. Overall, our findings revealed that salinity stress substantially affects all traits associated with germination and early seedling growth, with the effect of salinity being dependent on the level of stress applied. The journal encourages publications with an interdisciplinary approach. Plant Biology accepts. Extensive studies have been undertaken on senescence processes in barley and wheat and their importance for the nitrogen use efficiency of these crop plants. This journal aims to acknowledge and encourage interdisciplinary research in fundamental plant sciences with scope to address crop improvement, biodiversity, nutrition and human health. CO2 enrichment promoted aboveground biomass (+11.8%) and grain yield (+10.4%). 1. Whether this really leads to an increase in performance depends on other abiotic and biotic factors, most prominently potentially changing precipitation patterns. We tested pollen transfer by diverse foraging bees and viability of pollen from both stamen types. The proportion of females was not unimodally but positively linearly related to genetic diversity. Most of the proteins degraded reside in the chloroplasts, with Rubisco constituting the most dominant protein fraction. Our data indicate a peculiar fine‐tuning of developmental shifts during late‐leaf development that is controlled by TFs. About the journal. Special Issue Special issue is an effective way for researchers to focus on a hot topic for an in-depth study. Despite suggestions that senescence and PCD are two separate processes, with PCD occurring after senescence, cell death responsible for senescence is accompanied by numerous changes at the cytological, physiological and molecular levels, similar to other types of PCD. ), European beech (Fagus sylvatica [L.]) and sessile oak (Quercus petraea (Matt.) Activities of NAD‐dependent MDHs have been detected in mitochondria, peroxisomes, cytosol and plastids. The techniques used for measurement of gas exchange fluxes between the atmosphere and vegetation are outlined. We examined germination across a wide thermal profile to depict species‐specific characteristics and assessed the potential of gibberellic acid (GA, Of the tested species, 81% produce seeds that are dormant at maturity. Journal home; Volumes and issues; Search within journal. Despite intensive studies, the proteases responsible for Rubisco degradation have not yet been identified. It is often inseparable from programmed cell death (PCD), and a correlation between these processes has been confirmed during the senescence of leaves and petals. Journal of Plant Biology. However, in small populations, sex ratios may be strongly male‐ or female‐biased, leading to substantial reductions in effective population size. Our systems will continue to remind you of the original timelines but we intend to be highly flexible at this time. The Journal publishes original articles, reviews and brief communications detailing significant research contributions to plant science. Given that germination is the most critical phase in the plant life cycle, the present study aimed to determine seed germination potential and associated traits under salt stress conditions as a simple approach to identify salt‐tolerant lentil genotypes. Deadline: 30 June 2021 (full article submission). However, during cultivation, plants experience novel environmental conditions compared to those in natural populations, and there is a danger that the plants in cultivation are subject to unintended selection and lose their adaptation to natural habitats. In general, mean germination across the thermal profile was improved by GA. Our findings demonstrate the utility of dormancy classification as a foundation for understanding the critical regenerative traits in these ecologically important species and highlight its importance in restoration planning. Plant development and root patterning is disturbed, and this response depends on redox and reactive oxygen species signalling, calcium and plant hormones. We are pleased to announce that Plant Biology authors can now purchase professional video abstracts from Research Square. Functional Plant Biology publishes new and significant information on the functional biology of plants at all scales from the molecular through whole plant to community.

Medium‐sized to large bees sonicated flowers in a specific position, and the probability of pollen transfer correlated with bee size even among these legitimate visitors. Plant Biology is an international journal of broad scope bringing together the different subdisciplines, such as physiology, molecular biology, cell biology, development, genetics, systematics, ecology, evolution, ecophysiology, plant-microbe interactions, and mycology. Anther rostrum and pore morphology serve to direct and focus the pollen jet released by floral sonication towards the pollinator's body. Minerals such as potassium, molybdenum and lead increased, while manganese, iron, cadmium and silicon decreased, suggesting that adjustments of agricultural practices may be required to retain current grain quality standards. TRISO) was grown for three consecutive seasons in a free‐air carbon dioxide (CO2) enrichment (FACE) field experiment in order to examine the effects on crop yield and grain quality. These vesicles may then take different routes for their degradation. The tropical Melastomataceae are characterized by poricidal anthers which constitute a floral filter selecting for buzz‐pollinating bees. Read the latest articles of Journal of Plant Physiology at ScienceDirect.com, Elsevier’s leading platform of peer-reviewed scholarly literature The shape, cell height and roughness of floral epidermal cells varies among species, but is not correlated with pollinators at large. Deadline: 31 May 2021 (full article submission), Plant Biology is now inviting submissions for an upcoming Special Issue: Regulatory Hubs in Plant Stress Adaptation (potential title). A considerable number of the senescence‐regulated TF genes were found to respond to abiotic stress, and salt stress appeared to be the major factor controlling their expression. We recommend caution, particularly in selfing and short‐lived species, where evolution may be more rapid and effects may thus be more severe. Volume 63, issue 5 articles listing for Journal of Plant Biology Indices for resistance, recovery and resilience were applied for quantifying the tree growth reaction on the episodic drought stress in 1976 and 2003. This work is intended as a review of gas exchange processes between the atmosphere and the terrestrial vegetation, which have been known for more than two centuries since the discovery of photosynthesis. © 2020 Springer Nature Switzerland AG. Phenotypic traits are generated by images of RGB, hyperspectral, near-infrared, thermal, fluorescence imaging and so on. Thirty crop species provide 90% of our food, most of which display severe yield losses under moderate salinity. With regard to mixing and rheological properties of the flour, a significant increase in gluten resistance under elevated CO2 was observed. Published on behalf of the German Society for Plant Sciences and the Royal Botanical Society of the Netherlands, Plant Biology is an international journal of broad scope bringing together different subdisciplines, such as physiology, molecular biology, cell biology, development, genetics, systematics, ecology, evolution, ecophysiology, plant-microbe interactions, and mycology. In this study, we investigated size scaling of respiration rate, fresh mass and surface area of leaves, stems and roots in 65 seedlings of Fagus crenata Blume (2 weeks to 16 months old). We thus conclude that conical epidermal cells probably play a role in plant reproduction other than providing grip or tactile cues, such as increasing hydrophobicity or enhancing the visual signal. Corresponding to the decline in grain protein concentration, CO2 enrichment resulted in an overall decrease in amino acid concentrations, with greater reductions in non‐essential than essential amino acids.
