摘要： The CYP78A gene family, a plant-specific subfamily of cytochrome P450 enzymes, plays pivotal roles in plant growth, development, and stress responses. Although the CYP78A genes in many plants have been widely studied, little is known about them in Lycium. In this study, we identified six CYP78A genes in both Lycium barbarum and Lycium ruthenicum through comprehensive bioinformatics analysis. These genes exhibited high conservation in protein structure, gene organization, and conserved motifs. Phylogenetic analysis revealed they are close in terms of homology to CYP78A genes in Arabidopsis, tomato, and eggplant. Cis-acting element analysis of the promoter regions indicated that CYP78A genes are involved in light, hormone, and stress responses, with tissue-specific expression patterns observed across different developmental stages. Subcellular localization experiments confirmed that LrCYP78A5 is localized in the endoplasmic reticulum. Overexpression of LrCYP78A5 in L. ruthenicum resulted in a significant increase in chlorophyll content, indicating the former's potential role in plant growth. These findings provide valuable insights into the functional roles of the CYP78A gene family in goji, highlighting their potential involvement in growth regulation and metabolic processes.
