The alpha-ketoglutarate-dependent dioxygenase (AlkB) gene family plays an essential role in regulating plant development and stress response. However, the AlkB gene family is still not well understood in cotton. In this study, 40 AlkB genes in cotton and Arabidopsis are identified and classified into three classes based on phylogenetic analysis. Their protein motifs and exon/intron structures are highly conserved. Chromosomal localization and synteny analysis suggested that segmental or whole-genome duplication and polyploidization events contributed to the expansion of the cotton AlkB gene family. Furthermore, the AlkB genes showed dynamic spatiotemporal expression patterns and diverse responses to abiotic stresses. Among them, GhALKBH10 was down-regulated under various abiotic stresses and its subcellular expression was localized in cytoplasm and nucleus. Silencing GhALKBH10 in cotton increased antioxidant capacity and reduced cytoplasmic Na |
