Mechanisms of abiotic stress responses and tolerance in plants: physiological, biochemical and molecular interventions

Abiotic stresses such as drought (water deficit), excessive watering (water-logging/flooding), extreme temperatures (cold, frost, and heat), salinity (sodicity) and mineral (metal and metalloid) toxicity negatively impact growth, development, yield, and seed quality of crop and other plants. Similarly, large losses of grain yields in plants occur as a result of pathogen attack, in particular during vulnerable stages of grain development and germination. In addition, the predicted scarcity of fresh water implies that the intensity of abiotic stresses will increase. Hence, there is an urgency to develop crop varieties that are resilient to abiotic stresses to ensure food security and safety for many years to come. Progress acquired via breeding to develop abiotic stress-tolerant crops is slow due to multigene origins of plant adaptive responses and involvement of complex genetic mechanisms. For plants to survive under stress conditions, they have evolved complex mechanisms to perceive external signals that allow plants to respond to changing environmental conditions. These mechanisms include stress perception, signal transduction, transcriptional activation of stress-responsive target genes, and synthesis of stress-related proteins and other molecules, which assist plants to cope with adverse environmental conditions through biochemical and physiological manifestations.

Importantly, understanding the connection between a plant's initial stress response and downstream events to adjust to altered conditions is one of the grand challenges in plant biology. Intensive research over the last decade has gradually unraveled the mechanisms that underlie how plants cope with abiotic stresses, but many aspects remain unresolved. The complete understanding of physiological, biochemical, and molecular responses and tolerance mechanisms, and identification of potential unknown stress-responsive pathways and genes in abiotic plant stress tolerance will contribute to a better understanding of underlying molecular mechanisms. Discoveries of novel genes and pathways, analyses of expression patterns, and the determination of the function of genes during abiotic stress adaptation will provide the basis for effective engineering strategies with the aim to enhance abiotic stress tolerance of crop plants. The new knowledge acquired through this research will help in the application of stress-responsive determinants and in the engineering of plants with enhanced tolerance to abiotic stresses.

In this Research Topic, we intend to incorporate the contributions from leading plant scientists focusing on a variety of abiotic stress tolerance mechanisms using physiological, biochemical, molecular, structural, and systems biology approaches. Authors are invited to submit original research, reviews/mini-reviews, methods, and opinion articles related to, but not exclusively limited to, the following topics:
o Responses of plants to abiotic stresses from gene to a whole plant level
o Mechanisms of abiotic stress responses and tolerance
o Contributions of novel pathways and genes in modulating abiotic stress tolerance
o Physiological, biochemical, and molecular studies of plant responses to abiotic stresses
o Stress perception mechanisms and stress downstream gene activation
o Comparisons of stress conditions revealing general and stress-specific mechanisms
o Descriptions and roles of stress-responsive genes, proteins, and transcription factors
o Transcriptional regulons at the plant level in response to abiotic stresses
o Marker-assisted selection towards generating abiotic stress-tolerant crop plants
o Genetic engineering and genome editing for abiotic stress tolerance
o Biotechnological approaches to study abiotic stress
