1、分子微生物學 2、昆蟲病理學

本人的研究興趣主要有兩個方面。一、以病原真菌與寄主昆蟲為模式，研究病原菌與寄主之間的相互作用，特別是細胞壁組成和結構變化影響真菌侵染致病的作用機制。真菌細胞壁是真菌細胞外的重要結構，為真菌抵禦機械壓力和不良環境等提供保護，主要由多糖和蛋白組成。在侵染過程中，真菌細胞壁的結構和組成發生複雜的動態變化，以利於真菌附着寄主體壁、躲避寄主體內免疫識別等。因此，研究侵染致病過程中細胞壁的結構組成變化與真菌侵染致病的關係，對於闡明昆蟲病原真菌的侵染致病機理具有重要意義和實際應用價值。二、產孢是真菌無性繁殖的主要方式，與殺蟲真菌的生產效率直接相關。絲狀真菌通常具有兩種產孢模式：正常產孢和微循環產孢。綠僵菌微循環產孢的孢子產量和質量均優於正常產孢，具有良好的應用潛力。營養可調控絲狀真菌產孢模式轉換，但機制尚不清楚。因此，明確營養調控昆蟲病原真菌產孢模式轉換的分子機制，有望為提高孢子的生產效率提供理論依據和技術途徑。 ^[1]
