Comprehensive analysis and expression characterization of potato Cytochrome P450 gene family and the role of StCYP67 in abiotic stresses

558 members of the StCYP450 family in potato were identified, many of which appear to participate in abiotic stress responses. Functional validation of StCYP67 highlights its dual role in BRs biosynthesis and stress regulation. These results not only clarify the evolutionary relationships within the StCYP450 gene family but also establish a foundation for future functional studies of these genes in potato.
