The Interference of Mnsod3 Enhances the Tolerance of Pleurotus ostreatus Mycelia to Abiotic Stress by Reshaping the Cell Wall.

ABSTRACT: In recent years, the response mechanism of Pleurotus ostreatus to abiotic stress has received widespread attention. MnSOD is an important antioxidant enzyme that has been widely studied in animals and plants because of its functions. However, there is little research on the function and regulatory mechanism of MnSOD in the growth and development of edible fungi. This study investigated the role of Mnsod3 in the growth and development of P. ostreatus. The results showed that during the nutritional growth stage, heat stress can cause the cell wall of mycelia to shrink and the cells to exhibit cytoplasmic wall separation. RNA-seq revealed that Mnsod3 interference is strongly correlated with increased transcript levels of cell wall synthase genes and with increased
