About this Research Topic
Abiotic stress, which includes extreme temperature, salinity, drought, and environmental pollution with heavy metals, is a global agricultural issue that results in considerable yield and quality loss for crops. With the continued rise of the world's population, sustainable agriculture and food security must develop advanced breeding strategies that effectively mitigate abiotic stress. Additionally, a multifaceted strategy is required for crops to enhance their ability to adapt to abiotic stress, including hormone modulation, plant enzymatic system activation, and stress gene expression. Thus, understanding how cereal crops react to abiotic stress is crucial. Further study is necessary on the characteristics of abiotic stress and how their underlying physiological, biochemical, and molecular (genetic, epigenetic, transcriptomic, and metabolomic) bases can contribute to breeding efforts to create abiotic stress-resistant crops.
The goal of this Research Topic is to offer up-to-date scientific evidence and potential for future research to improve our knowledge of the mechanisms that control the development of abiotic stress tolerance in the world's major crop species. All facets of abiotic stress in crop plants will be covered in this topic, which will provide current and in-depth scientific knowledge on agronomic, morphological, physiological, biochemical, metabolomics, molecular, genomic, genetic, or epigenetic modifications that can later be used to create tolerant crop varieties.
This Research Topic explores the genetic, epigenetic, transcriptomic, and metabolomic underpinnings of all features connected to crop abiotic stress tolerance. We invite all article types that are welcomed in the section Plant Abiotic Stress. We especially encourage manuscripts that address:
• Advanced crop breeding applications for increasing abiotic stress resistance in crops
• Novel plant growth regulators for enhancing abiotic stress tolerance in plants
• Metabolomic and molecular strategies to improve abiotic stress resistance in crops
• Genetic mechanisms related to abiotic stress tolerance in plants and their related traits in plants by quantitative trait loci (QTL) mapping, genome-wide association (GWAS) investigation, or QTL-sequencing
• Epigenetic bases of abiotic stress resistance and their applications in crop breeding
Please note that descriptive studies will not be considered for review unless they provide substantial contribution to the mechanistic understanding of crop response to abiotic stress.
