This study identifies the potential role in heat-stress mitigation of phytohormones and other secondary metabolites produced by the endophytic fungus paecilomyces formosus LWL1 in japonica rice cultivar Dongjin. The japonica rice was grown in controlled chamber conditions with and without P. formosus LWL1 under no stress (NS) and prolonged heat stress (HS) conditions. Endophytic association under NS and HS conditions significantly improved plant growth attributes, such as plant height, fresh weight, dry weight, and chlorophyll content. Furthermore, P. formosus LWL1 protected the rice plants from HS compared with controls, indicated by the lower endogenous level of stress-signaling compounds such as abscisic acid (25.71%) and jasmonic acid (34.57%) and the increase in total protein content (18.76%–33.22%). Such fungal endophytes may be helpful for sustainable crop production under high environmental temperatures.


目的:研究在高温胁迫环境下内生菌(Paecilomyces formosus LWL1)对粳稻生长的影响。
创新点:首次探讨P. formosus LWL1产生的植物激素和有机酸在缓解粳稻热应激方面的作用。
方法:比较正常和高温胁迫两种环境下,P. formosus LWL1对Dongjin粳稻植株的生长状况及内源性脱落酸、茉莉酸和总蛋白水平变化的作用。
