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

4) Synergistic plant-microbe interactions: A way forward to remediate polluted soils
5) Osmolytes and abiotic stress: Responses and adaptations
6) Advanced tools for crop improvement programs
7) Plants under biotic and abiotic stress
8) Biotechnological tools to develop climate resilient crops

9) CRISPR/CAS9-a genome editing technology to develop abiotic stress tolerant plants

10) Advanced phenotyping tools in the plant ecophysiology

  • 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

  • Effects of Piriformospora indica on the Respiration of Taxus chinensis var. mairei under Water Stress
  • Abstract Seedlings of Taxus chinensis var. mairei were used as experimental materials to study the adaptation of Piriformospora indica to this plant under water stress. The materials were divided into two groups, namely, with or without inoculation with P. indica. Each group was subjected to four different levels of water stress. Vitality and physiological and biochemical indexes of the roots of T. chinensis var. mairei were regularly measured. Under water stress, T. chinensis var. mairei had significantly decreased root vitality; root vitality was higher in inoculated roots than in uninoculated roots. Under intense water stress, the inoculated roots had a higher… More

  • Structural and Histochemical Features of the Slow-Growing Perennial Coptis chinensis Franch. (Ranunculaceae)
  • Abstract Huanglian (Coptis chinensis Franch.) is a slow-growing perennial medicinal herb with considerable economic value. This study aimed to determine the structural characteristics and the levels of berberine deposits in the organs and tissues of Huanglian using light and epifluorescence microscopy. The adventitious roots are composed of primary and secondary structures with endodermis, exodermis, and phellem. The rhizome structures are composed of primary and secondary structures with cuticle and phellem. The leaves are composed of sclerenchymatous rings, isolateral mesophyll, and thin cuticles. We detected berberine in the xylem walls of the roots and rhizomes as well as in the sclerenchymatous rings… 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

  • Phenotypic and Molecular Assessment of Wheat Genotypes Tolerant to Leaf Blight, Rust and Blast Diseases
  • Abstract Globally among biotic stresses, diseases like blight, rust and blast constitute prime constraints for reducing wheat productivity especially in Bangladesh. For sustainable productivity, the development of disease-resistant lines and high yielding varieties is vital and necessary. This study was conducted using 122 advanced breeding lines of wheat including 21 varieties developed by Bangladesh Wheat and Maize Research Institute (BAMRI) with aims to identify genotypes having high yield potential and resistance to leaf blight, leaf rust and blast diseases. These genotypes were evaluated for resistance against leaf blight and leaf rust at Dinajpur and wheat blast at Jashore under field condition.… More

  • Cloning and Bioinformatics Analysis of the GlROP6 gene in Glehnia littoralis
  • Abstract Rho-related GTPase from plants (ROP) proteins play an essential role in plant stress resistance. In this study, the full-length GlROP6 gene was cloned based on G. littoralis transcriptome sequencing data acquired in response to salt stress. The protein sequence, conserved domains, secondary structure, three-dimensional structure, phylogenetic relationships, and expression pattern of the GlROP6 gene were systematically analysed. Our results showed that the full-length GlROP6 gene had an open reading frame of 606 bp, which encoded 201 amino acid residues with a relative molecular weight of 22.23463 kDa and a theoretical isoelectric point of 9.06. Amino acid sequence analyses indicated that… More
