Summary

Plant systems, both natural and managed, face a wide range of environmental challenges, which are expected to become more intense because of global climate change. Plants have adapted to an incredible range of environments and the fields of ecological and environmental plant physiology have provided mechanistic understanding of the survival, distribution, productivity, and abundance of plant species across the diverse climates of our planet. Ecophysiological techniques have greatly advanced understanding of photosynthesis, respiration, plant water relations and plant responses to abiotic and biotic stresses, from instantaneous to evolutionary timescales. Ecophysiological studies also provide the basis for scaling plant physiological processes from the tissue to the canopy, ecosystem, region and globe. Advancing ecophysiological understanding and approaches to enhance plant responses to new environmental conditions is critical to developing meaningful high-throughput phenotyping tools and maintaining humankind’s supply of goods and services as global climate change intensifies. Therefore, new and improved methods and tools for the production of stress-tolerant plant production with increasing yield and agronomical traits are needed. In recent years, ever-increasing plant multi-omics and bioinformatic tools are used to unravel deeper molecular biological insights imparting plant tolerance to diverse stress mechanisms. The development of last-generation high-throughput screening technologies, known as omics, promises to speed up trait improvement in plants. Hence, this Special Issue aims to integrate recent innovative high-throughput sequencing and computational omics approaches such as genomics, epigenomics, transcriptomics, proteomics, hormonomics, metabolomics, ionomics and phenomics and other related topics which include breeding, biotechnology, biochemistry, systems biology and agricultural practices to make novel progress in delineating the molecular and cellular systems level aspects of stress tolerant plant production. Specifically, we welcome studies that explore the uses of the omics paradigm and their integration through trans-disciplinary bioinformatics, as tools to improve qualitative and quantitative traits in crop species. This issue also illustrates the central role for plant ecophysiology in applying basic research to address current and future challenges to humankind, in particular in conservation of natural ecosystems and adaptation of agriculture to biotic/abiotic stress and global climate change.

Potential topics may include, but are not limited to:
1) Influence of climate change on crop physiology
2) Advanced technologies to mitigate the impact of climate change

3) Multi-omics approach to study plant-abiotic stress mechanisms

  • Effect of UV Radiation and Other Abiotic Stress Factors on DNA of Different Wild Plant Species Grown in Three Successive Seasons in Alpine and Subalpine Regions
  • Abstract Plants in natural ecosystems are exposed to a combination of UV radiation, ionizing radiation (IR) and other abiotic factors. These factors change with the altitude. We investigated DNA alterations of some wild plants of different plant families in natural ecosystems at three altitudes in Rila Mountain, Bulgaria (1500, 1782, and 2925 m above sea level (a.s.l.) exposed to UV radiation, IR and other abiotic stresses, to assess the tolerance of plant species to the changing environmental conditions in three successive growth seasons. For this purpose, physicochemical, cytogenetic, and molecular methods were applied. DNA damage was assessed by micronucleus test and molecular… More

  • Light Intensity Affects the Coloration and Structure of Chimeric Leaves of Ananas comosus var. bracteatus
  • Abstract Ananas comosus var. bracteatus is an important ornamental plant because of its green/white chimeric leaves. The accumulation of anthocyanin makes the leaf turn to red especially in the marginal part. However, the red fades away in summer and winter. Light intensity is one of the most important factors affecting leaf color along the seasons. In order to understand the effects of light intensity on the growth and coloration of the chimeric leaves, Ananas comosus var. bracteatus was grown under full sunlight, 50% shade and 75% shade for 75 days to evaluate the concentration of pigments, the color parameters (values L*,… More

  • Exogenous Glycine Betaine Reduces Drought Damage by Mediating Osmotic Adjustment and Enhancing Antioxidant Defense in Phoebe hunanensis
  • Abstract Drought stress negatively impacts growth and physiological processes in plants. The foliar application of glycine betaine (GB) is an effective and low-cost approach to improve the drought tolerance of trees. This study examined the effect of exogenously applied GB on the cell membrane permeability, osmotic adjustment, and antioxidant enzyme activities of Phoebe hunanensis Hand.-Mazz under drought stress. Two levels (0 and 800 mL) of water irrigation were tested under different applied GB concentrations (0, 50, 100, and 200 mM). Drought stress decreased the relative water content by 58.5% while increased the electric conductivity, malondialdehyde, proline, soluble proteins, soluble sugars, and antioxidant… More

  • Effects of Region and Elevation on Adaptation of Leaf Functional Traits of an Invasive Plant Erigeron annuus in China
  • Abstract A key scientific challenge relating to the threat of invasive plants on agriculture at the region level is to understand their adaptation and evolution in functional traits. Leaf functional traits, related to growth and resource utilization, might lead to adaptation of invasive plants to the geographical barriers (region or elevation). In the field experiment, we discussed the effects of region and elevation on leaf functional traits on invasive plant Erigeron annuus in farmland habitats in China. We compared leaf size, coefficient of variation (CV) of leaf traits, and fluctuating asymmetry (FA) of E. annuus from three regions (east vs. center… More

  • Villin Family Members Associated with Multiple Stress Responses in Cotton
  • Abstract Villin (VLN) is considered to be one of the most important actin-binding proteins, participates in modulating the actin cytoskeleton dynamics, plays essential role in plant development and resisting adverse environments. However, systematic studies of the VLN gene family have not been reported in cotton (Gossypium). In this study, 14 GhVLNs were identified in G. hirsutum. These GhVLN genes were distributed in 6 A-subgenome chromosomes and 6 D-subgenome chromosomes of the allotetraploid upland cotton and classified into three phylogenetical groups based on the classification model of AtVLNs. In addition, the 14 GhVLN genes have highly conserved gene structure and motif architecture.… More

  • Potentiality of Different Seed Priming Agents to Mitigate Cold Stress of Winter Rice Seedling
  • Abstract Seed priming has proved to be an effective pre-germination seed invigoration technique for different crops to improve seed and seedling performance under different abiotic stresses. In Bangladesh, winter rice is very often exposed to cold waves just after sowing in the nursery bed resulting in poor seed germination and seedling emergence, yellowish and thin seedlings production, and a very low survival rate. Seed priming may mitigate the cold stress during seed germination and seedling emergence and helps in the quality seedling production of winter rice. To evaluate the efficacy of different seed priming techniques in increasing seedling emergence, growth, vigor… More
