Abstract :
Genomics approaches have revolutionized
crop improvement by providing insights into the genetic
basis of abiotic stress tolerance in groundnut (Arachis
hypogaea L.). Abiotic stresses such as drought, heat,
salinity, and nutrient deficiencies pose significant
challenges to groundnut production and global food
security. This review highlights the key genomics
approaches employed in groundnut research to enhance
abiotic stress tolerance. Transcriptomics, including
RNA sequencing (RNA-Seq), has enabled the
identification of stress-responsive genes and regulatory
networks. Marker-assisted selection (MAS) and
quantitative trait loci (QTL) mapping have facilitated
the identification of molecular markers and genomic
regions associated with stress tolerance traits. Genomic
selection integrates genomic information and
phenotypic data for the prediction and selection of
stress-tolerant individuals. Gene editing technologies,
particularly CRISPR-Cas9, offer precise modification
of stress-related genes. Comparative genomics has
revealed conserved regions and genes associated with
stress tolerance across species. Genomic resources and
databases specific to groundnut aid in the identification
of candidate genes and the design of molecular markers.
These genomics approaches offer great potential for
developing stress-tolerant groundnut varieties, ensuring
sustainable agriculture, and addressing global food
security challenges.
