Genome-wide characterization of the cytochrome P450 gene family in Solanum melongena and functional analysis of SmCYP82C1 under cold stress.

ABSTRACT:

Background

Eggplant (Solanum melongena L.), a nutritionally valuable solanaceous crop, exhibits pronounced sensitivity to cold stress, which limits its growth and development. Cytochrome P450 (CYP450) enzymes are widely implicated in plant developmental regulation and abiotic stress responses; however, their functional roles in eggplant remain unexplored.

Results

In this study, we systematically identified 176 SmCYP450 homologs in the eggplant genome, which were phylogenetically classified into 24 distinct subfamilies. Evolutionary analysis revealed that segmental duplication events predominantly drove the expansion of the SmCYP450 family, and codon usage bias within these genes was primarily shaped by natural selection pressures. Notably, transcriptomic profiling identified
