Drought stress restricts plant growth and development by altering metabolic activity and biological functions. However, plants have evolved several cellular and molecular mechanisms to overcome drought stress. Drought tolerance is a multiplex trait involving the activation of signaling mechanisms and differentially expressed molecular responses. Broadly, drought tolerance comprises two steps: stress sensing/signaling and activation of various parallel stress responses (including physiological, molecular, and biochemical mechanisms) in plants. At the cellular level, drought induces oxidative stress by overproduction of reactive oxygen species (ROS), ultimately causing the cell membrane to rupture and stimulating various stress signaling pathways (ROS, mitogen-activated-protein-kinase, Ca2+, and hormone-mediated signaling). Drought-induced transcription factors activation and abscisic acid concentration co-ordinate the stress signaling and responses in cotton. The key responses against drought stress, are root development, stomatal closure, photosynthesis, hormone production, and ROS scavenging. The genetic basis, quantitative trait loci and genes of cotton drought tolerance are presented as examples of genetic resources in plants. Sustainable genetic improvements could be achieved through functional genomic approaches and genome modification techniques such as the CRISPR/Cas9 system aid the characterization of genes, sorted out from stress-related candidate single nucleotide polymorphisms, quantitative trait loci, and genes. Exploration of the genetic basis for superior candidate genes linked to stress physiology can be facilitated by integrated functional genomic approaches. We propose a third-generation sequencing approach coupled with genome-wide studies and functional genomic tools, including a comparative sequenced data (transcriptomics, proteomics, and epigenomic) analysis, which offer a platform to identify and characterize novel genes. This will provide information for better understanding the complex stress cellular biology of plants.

Cotton (Gossypium spp.) is the most important natural fiber crop worldwide. The diversity of Gossypium species also provides an ideal model for investigating evolution and domestication of polyploids. However, the huge and complex cotton genome hinders genomic research. Technical advances in high-throughput sequencing and bioinformatics analysis have now largely overcome these obstacles, bringing about a new era of cotton genomics. Here, we review recent progress in Gossypium genomics based on whole genome sequencing, resequencing, and comparative genomics, which have provided insights about the genomic basis of fiber biogenesis and the landscape of cotton functional genomics. We address current challenges and present multidisciplinary genomics-enabled breeding strategies covering the breadth of high fiber yield, quality, and environmental resilience for future cotton breeding programs. Gossypium Genomics at a Glance As the world's most important fiber crop and a major source of seed oil and protein, cotton is cultivated in more than 75 countries around the globe [1]. Cotton fibers are seed trichomes, up to 65 mm long, composed of almost pure cellulose, and provide a unique single-celled model system for studying cell elongation and cell wall biogenesis [2]. The Gossypium genus is extraordinarily diverse, with eight diploid genome groups (A-G, and K) and one allopolyploid group (AD) [3,4]. Hybridization and polyploidization of two parental diploids, an A genome-like species with a D genome-like species, has resulted in at least seven allotetraploid species. Two allotetraploid species, Gossypium hirsutum and Gossypium barbadense, evolved independently; these two account for over 90% of annual commercial fiber production. Gossypium is ideal for investigating the origin, evolution, and domestication of polyploids [5-7]. Highlights Cotton is an important natural fiber crop cultivated worldwide that also provides an ideal model for investigating evolution and domestication of polyploids Combinations of the latest technologies, such as optical mapping, high-throughput chromosome conformation capture (Hi-C), and Pacific Biosciences (PacBio) long-reads, have been used to generate multiple high-quality reference genomes of diploid and allotetraploid cotton. Comparative population genomics illuminated the genetic history of cotton domestication and identified the genomic variation determining fiber yield, quality, and stress resistance.

“…In Arabidopsis , strains overexpressing AtDREB2C are ABA hypersensitive during germination and show enhanced plant tolerance to cold and heat stress [ 8 ]. The overexpression of GhERF38 increased ABA sensitivity in seed germination and seedling period in Arabidopsis [ 52 ]. Our AhDREB1-OX lines were also ABA hypersensitive during seed germination and seedling development.…”

Drought stress negatively affects plant growth and development. An increasing number of reports have revealed the involvement of APETALA2/Ethylene Responsive Factor (AP2/ERF) transcription factors (TFs) in biotic and abiotic stress regulation in plants. However, research on these TFs in the peanut plant (Arachis hypogaea) has been limited. Here, we isolated a full-length coding sequence (CDS) of the AP2/ERF family gene AhDREB1 from the peanut plant and showed that its expression was induced by Polyethylene Glycol (PEG) 6000 and exogenous abscisic acid (ABA) treatment. When overexpressed in Arabidopsis, AhDREB1 increased both ABA levels and ABA sensitivity, affected the ABA signaling pathway and increased the expression of downstream drought stress-related genes RD29A, P5CS1, P5CS2 and NCED1. These results demonstrate that AhDREB1 can improve tolerance to drought via the ABA-dependent pathway in Arabidopsis. In the peanut plant, the specific histone deacetylases (HDACs) inhibitor trichostatin A (TSA) promotes AhDREB1 transcription and the enrichment level of H3ac was increased in regions of the AhDREB1 gene during TSA and PEG treatment. In summary, histone acetylation can affect the expression of AhDREB1 under osmotic stress conditions, thereby improving plant drought resistance.
