This collection features four peer-reviewed literature reviews on drought-resistant crops.

The first chapter assesses the genes involved in drought and heat tolerance, as well as the physiological traits related to increased tolerance to abiotic stress in wheat. It reviews advances in our understanding of the molecular markers associated with these physiological traits, and the roles of key genes in determining a wheat plant’s response to heat and drought stress.

The second chapter discusses mechanisms of drought resistance in rice. It reviews ways of assessing drought tolerance performance, identifying genes promoting drought tolerance through quantitative trait loci (QLT) analysis, as well as breeding for drought tolerance.

The third chapter highlights the genetic diversity and quantitative trait loci (QTL) associated with the traits contributing to drought and heat tolerance in soybean. It also reviews genomic resources that can facilitate a better understanding of phenotype-genotype associations and formulate genomic-assisted breeding strategies.

The final chapter addresses the polygenic nature of tolerance to drought and to heat in grain legumes. It reviews advances in understanding plant adaptation to stress, the assembly of molecular and phenotyping tools to support breeding and the development of tolerance through traditional and molecular breeding techniques.
