“…Their findings indicated that these genes were upregulated under heat stress conditions, suggesting their potential role in heat stress tolerance. Additionally, Bhogireddy et al [218] investigated the involvement of non-coding RNAs, including mRNAs and long non-coding RNAs (lncRNAs), in the response to heat stress in chickpeas. Through their study, they discovered 894 putative lincRNAs in leaf and root tissues under heat stress conditions, along with 61,110 mRNA-targeting genes associated with stress response, signaling, and metabolic processes.…”

Although chickpea (Cicer arietinum L.) has high yield potential, its seed yield is often low and unstable due to the impact of abiotic stresses, such as drought and heat. As a result of global warming, both drought and heat are estimated to be major yield constraints between one-quarter and one-third per annum. In the present review, genomic-mediated breeding strategies to increase resilience against global warming. Exacerbated drought and heat stresses have been examined to understand the latest advancement happening for better management of these challenges. Resistance mechanisms for drought and heat stresses consist of (i) escape via earliness, (ii) avoidance via morphological traits such as better root traits, compound leaves, or multipinnate leaves and double-/multiple-podded traits, and (iii) tolerance via molecular and physiological traits, such as special tissue and cellular abilities. Both stresses in chickpeas are quantitatively governed by minor genes and are profoundly influenced by edaphic and other environmental conditions. High-yield genotypes have traditionally been screened for resistance to drought and heat stresses in the target selection environment under stress conditions or in the simulacrum mediums under controlled conditions. There are many drought- and heat-tolerant genotypes among domestic and wild Cicer chickpeas, especially in accessions of C. reticulatum Ladiz., C. echinospermum P.H. Davis, and C. turcicum Toker, J. Berger, and Gokturk. The delineation of quantitative trait loci (QTLs) and genes allied to drought- and heat-related attributes have paved the way for designing stress-tolerant cultivars in chickpeas. Transgenic and “omics” technologies hold newer avenues for the basic understanding of background metabolic exchanges of QTLs/candidate genes for their further utilization. The overview of the effect of drought and heat stresses, its mechanisms/adaptive strategies, and markers linked to stress-related traits with their genetics and sources are pre-requisites for framing breeding programs of chickpeas with the intent of imparting drought tolerance. Ideotype chickpeas for resistance to drought and heat stresses were, therefore, developed directly using marker-aided selection over multiple locations. The current understanding of molecular breeding supported by functional genomics and omics technologies in developing drought- and heat-tolerant chickpea is discussed in this review.

During development and environmental stresses, plants experience genome-wide epigenetic alterations that are typically associated with differentiation in transcriptional gene expression.An epigenome is the aggregate of a cell's biochemical modi cations in its nuclear DNA, post-translational changes in histones, and differences in non-coding RNAs' biogenesis. Differences in gene expression that take place without any change in the underlying nucleotide sequence are frequently caused by these changes. Chromatin remodelling that can epigenetically dictate particular transcriptional outputs and change the function/activity of the genome include post-transcriptional histone modi cations, variations in histone proteins, DNA methylation, and activity of non-coding RNA. Epigenetic marks have a signi cant impact on how plants respond to environmental challenges, and recent developments in the eld of major crop "-omics" have made it easier to identify these marks. The phenotypic plasticity of the organism is impacted by the epigenomic alterations, which are dynamic in response to any endogenous and/or external stimuli. After the stress is withdrawn, both changes in gene expression and epigenetic alterations may quickly return to their pre-stress states. Few epigenetic alterations, which have been related to acclimatisation, adaptation, and the evolutionary process, might be retained, though. For better use of genetic resources, epigenome engineering may be used to improve plants' ability to withstand stress. In this chapter, we have outlined recent epigenetic studies that may be crucial for enhancing crop resilience and adaptation to environmental changes, ultimately resulting in the development of stable climate-smart crops.
