Genetic Regulation of Abiotic Stress Tolerance in Plants

Call for Papers

Abiotic stresses like drought, flooding, heat, cold, and high-salinity severely affect crop yield production worldwide. Understanding the genetic regulation of stress tolerance is very important to reduce the losses frequently occurring due to the abiotic stresses. In general, genetic regulation of abiotic stress tolerance is very complex and is governed by many genes and also affected by environmental conditions. In this regard, genetic mapping of quantitative trait loci (QTL) performed to dissect the trait and to identify regulatory genes/loci has great importance. Segregating population, genotyping techniques, molecular markers, and statistical tools are the deciding factors for the efficient QTL mapping. Recent advancement in sequencing technology has improved molecular marker discovery to several folds and provides cost effective high-throughput genotyping by sequencing (GBS). Similarly, availability of genome sequence enhances the efficiency of QTL mapping in many ways; for example, it provides source of genome-wide markers, helps to develop dense genetic linkage map, and facilitates candidate gene identification.

The two principal applications of QTL mapping are map-based cloning of regulatory genes and marker assisted breeding. Despite the discovery of thousands of QTLs, exploitation of QTL information in map-based cloning and breeding programs remains limited and is further complicated because of nonconsistent and relatively small effect QTLs. To address this, approaches like meta-QTL analysis provide statistical relevance to select realistic QTL even with small effect. In addition to conventional methods, several novel approaches employing technical advances are being developed and applied. Genome-wide association study (GWAS) is one of the most efficient methods utilizing recent advances in NGS and statistical tools. Similarly, multiparental populations like Nested Association Mapping (NAM) and Multiparent Advanced Generation Intercrosses (MAGIC) populations provide several benefits over the conventional biparental populations particularly for the complex traits like abiotic stress tolerance.

This special issue will provide an overview of QTL mapping and its utilization for the elevation of abiotic stress tolerance in plants. In addition, this issue aims to highlight the novel approaches such as high-resolution mapping, marker development, transcriptome profiling used to identify candidate genes and markers, and other breeding efforts applied towards the translational research employing QTL information. Furthermore, it also focuses on the functional evaluation of candidate genes, gene interactions, expression profiling, statistical methods, and integrated approaches used for understanding the complex molecular mechanism involved in the stress tolerance mechanism. We invite reviews and original research articles related to genetic regulation of abiotic stress tolerance in plants.

Potential topics include but are not limited to the following:

  • Genetic dissection of abiotic stress tolerance in plants
  • Identification of QTLs for abiotic stress related traits in plants
