砖红镰刀菌菌株Pa2对草莓灰霉病的抑制作用
Inhibitory Effect of Fusarium lateritium Pa2 against Strawberry Gray Mold
摘要
Abstract
Strawberry gray mold caused by Botrytis cinerea is one of the most destructive diseases in strawberry cultivation,which seriously reduces the edible and economic value.In this study,"Hongyan"strawberries were used as experimental materials to determine the effects of Fusarium lateritium Pa2 on the inhibitory activity and control of gray mold pathogen,as well as the effects on the pathogenesis-related genes expression levels of strawberry fruit.The results showed that strain Pa2 had significant antifungal activity against B.cinerea.The supernatant of strain Pa2 could damage the mycelial cell membrane of B.cinerea,leading to leakage of cell contents.The results of inoculation experiments indicated that the control effects of strain Pa2 on strawberry leaves gray mold and strawberry fruits gray mold were 79.13％and 54.29％,respectively.In addition,the strawberry fruits pathogenesis-related genes FaPR1,FaPR4,and FaGR increased by 19.05,24.64,and 3.69 times at 24 hours post treatment with supematant of strain Pa2,respectively.In conclusion,the F.lateritium strain Pa2 is a new biocontrol resource for controlling strawberry gray mold.关键词
