Such genomic regions offer valuable insights into the molecular mechanisms that influence quantitative traits. India harbours a diverse buffalo population with Murrah breed exhibiting exceptional milk production and quality, notably a high fat and solids-not-fat content. Therefore, the present investigation focused on exploring selection signatures within the genome of the Murrah buffalo through whole-genome resequencing. A total of 17 472 799 SNPs were identified, which were further utilized for identification of selection signatures using site frequency spectrum-based Tajima's D and Nucleotide Diversity; and linkage disequilibrium-based iHS approaches. A total of 248 regions under selection overlapped with 64 QTLs across various traits (milk, production, reproduction, meat and carcass, health, and exterior) on chromosomes 5, 9, and 17. A majority of the identified QTLs (39) were associated with milk-related traits, with 27 QTLs specifically linked to milk fat content. Notably, genes such as <i>ARHGAP26, ADGRL3</i>, and <i>SUCLG2</i> mapped within the QTLs under selection are implicated in milk traits, while <i>XPR1</i> is associated with growth. Hub genes included <i>RPL23A, ADGRL</i>3 (milk); <i>AP3B1, TXN2</i> (reproduction); <i>CDK6, IGF2R</i> (body confirmation), and <i>HSPA9</i> (heat tolerance).

The advent of transgenic breeding allowed for the direct insertion of foreign genes, leading to the development of crops with herbicide tolerance, pest resistance, and improved nutritional content. However, concerns over regulatory restrictions and public acceptance have driven the rapid adoption of genome editing tools, which enable precise modifications without introducing foreign DNA. Canada has played a key role in applying these biotechnological innovations, successfully developing genetically modified canola, CRISPR-edited wheat, stress-resistant soybean, and barley and oat cultivars improved for stress resistance and yield.
