Abstract
Lagerstroemia indica, a species renowned for its ornamental attributes, occupies a vital position in garden landscaping, and CYP450 constitutes a group of proteins functioning as monooxygenases, which are extensively implicated in plant growth, development, and various other life processes. There are 314 members in total belonging to the CYP450 family, which were identified within the genome of Lagerstroemia indica, with their distribution spanning 23 chromosomes. Based on diverse structural domains as well as evolutionary analysis, the CYP450 family is divided into nine subfamilies; segmental duplication serves as the chief amplification mode during the development trajectory of the CYP450 gene family, the CYP75 subfamily genes LiF3'H and LiF3'5'H, which were found to localize to the cell membrane and promote anthocyanin synthesis. The results obtained from this study are of great significance as they delve deeper into the functional contributions of CYP450 genes by establishing a firm basis and for investigating the molecular processes involved in anthocyanin synthesis in Lagerstroemia indica.
