“…The resolution for locating novel genes, alleles, and QTLs is improved when this bi-parental mapping population is combined with GBS and GWAS [39,74]. PEG/water deprivation stress conditions were used to create a collection of ESTs from entire plant tissues of pigeonpea [75]. From pigeonpea plants treated with 10% polyethylene glycol, two subtracted cDNA libraries were created (PEG-6000).…”

Cajanus cajan (L.) Millsp. is an adaptable, resilient, and nutrient-dense grain legume with qualities that can help agricultural systems become more sustainable in subtropical and tropical regions. Extremes in moisture, temperature, photoperiod, and mineral-related stressors are the most significant that encounter throughout the life cycle. Different stress slows down the plants’ growth by upsetting its typical physiology and morphology. Inefficient conditions can occur sequentially or simultaneously in environments, and plants have evolved defense mechanisms to continue to grow and survive under less-than-ideal edaphic and climatic factors. Although various genotypes of pigeonpea have been identified that are tolerant to heat, drought, and waterlogging, new empirical evidence reveals that genotypic changes have been detected for all of the abiotic stimuli in this crop. Furthermore, to enhance tolerance, breeding techniques or methods such as marker features, including extensive hybridization, double haploids, tissue culture, somaclonal variants, genetic transformation, and marker-assisted breeding, have been employed to lessen the effect of these stressor. These methods help in the development of enhanced germplasm with abiotic stress tolerance and disease resistance, resulting in higher crop quality and production. This chapter focuses on different abiotic stressors and the methods that have been employed to help pigeonpea to overcome environmental constraints.

“…From pigeonpea plants treated with 10% polyethylene glycol, two subtracted cDNA libraries were created (PEG-6000). Among the many ESTs found, three stress-responsive genes, CcHyPRP [76], CcCDR [77], and CcCYP [75], demonstrated extraordinary resistance to different abiotic stimuli in transgenic Arabidopsis.…”

The world is facing rapid climate change and a fast-growing global population. It is believed that the world population will be 9.7 billion in 2050. However, recent agriculture production is not enough to feed the current population of 7.9 billion people, which is causing a huge hunger problem. Therefore, feeding the 9.7 billion population in 2050 will be a huge target. Climate change is becoming a huge threat to global agricultural production, and it is expected to become the worst threat to it in the upcoming years. Keeping this in view, it is very important to breed climate-resilient plants. Legumes are considered an important pillar of the agriculture production system and a great source of high-quality protein, minerals, and vitamins. During the last two decades, advancements in OMICs technology revolutionized plant breeding and emerged as a crop-saving tool in wake of the climate change. Various OMICs approaches like Next-Generation sequencing (NGS), Transcriptomics, Proteomics, and Metabolomics have been used in legumes under abiotic stresses. The scientific community successfully utilized these platforms and investigated the Quantitative Trait Loci (QTL), linked markers through genome-wide association studies, and developed KASP markers that can be helpful for the marker-assisted breeding of legumes. Gene-editing techniques have been successfully proven for soybean, cowpea, chickpea, and model legumes such as Medicago truncatula and Lotus japonicus. A number of efforts have been made to perform gene editing in legumes. Moreover, the scientific community did a great job of identifying various genes involved in the metabolic pathways and utilizing the resulted information in the development of climate-resilient legume cultivars at a rapid pace. Keeping in view, this review highlights the contribution of OMICs approaches to abiotic stresses in legumes. We envisage that the presented information will be helpful for the scientific community to develop climate-resilient legume cultivars.
