Abstract

Cytochrome P450 (CYP) is a crucial oxidoreductase enzyme that plays a significant role in plant defense mechanisms. In this study, a specific cytochrome P450 gene () was discovered in mulberry (). Bioinformatic analysis and expression pattern analysis were conducted to elucidate the involvement of in combating infection. After the infection of , there was a notable increase in the expression of . is overexpressed in Arabidopsis and mulberry and strongly reacts to . The overexpression of the gene in Arabidopsis and mulberry led to a substantial enhancement in resistance against , elevated catalase (CAT) activity, increased proline content, and reduced malondialdehyde (MDA) levels. At the same time, HO and O levels in transgenic Arabidopsis were decreased, which reduced the damage of ROS accumulation to plants. Furthermore, our research indicates the potential involvement of in resistance through the modulation of other resistance-related genes. These findings establish a crucial foundation for gaining deeper insights into the role of cytochrome P450 in mulberry plants.
