![hide entries hide](./images/icon_minus_white.png)
impairment of pyrroline-5-carboxylate oxidation in the p5cdh mutant does not change the cellular Pro to P5C ratio under ambient and osmotic stress conditions. Lack of P5CDH activity leads to higher ROS production under dark and light conditions in the presence of Pro excess, as well as renders plants hypersensitive to heat stress
