BrCYP71A15 Negatively Regulates Hg Stress Tolerance by Modulating Cell Wall Biosynthesis in Yeast.

ABSTRACT: Over the past two decades, heavy metal pollution has been a common problem worldwide, greatly threatening crop production. As one of the metal pollutants, Mercury (Hg) causes damage to plant cells and reduces cellular and biochemical activities. In this study, we identified a novel cytochrome P450 family gene, BrCYP71A15, which was involved in Hg stress response in yeast. In Chinese cabbage, the BrCYP71A15 gene was located on chromosome A01, which was highly expressed in roots. Additionally, the expression level of BrCYP71A15 was induced by different heavy metal stresses, and the BrCYP71A15 protein exhibited a strong interaction with other proteins. Overexpression of BrCYP71A15 in yeast cells showed no response to a number of heavy metal stresses (Cu, Al,
