摘　　要：漆酶参与木质素的降解和食用菌的生长发育。为了明晰漆酶基因在糙皮侧耳生长发育过程中的作用,本文采用real-time PCR检测了11条漆酶基因及Lacc2的小亚基sspoxa3在糙皮侧耳生长发育不同阶段的表达。其中lacc6和sspoxa3在整个生长发育阶段表达量均较高;lacc12随着原基的分化和子实体的形成大量表达,与成菇过程有关。lacc4,lacc7和lacc11在原基分化期高表达,与原基的分化有关。lacc2,lacc3和lacc8在成熟子实体阶段表达量显著上升,与子实体的分化和成熟有关。Laccases are involved in lignin degradation and mushroom development. In order to further determine the role of accases in fruiting of Pleurotus ostreatus, expressions of 11 laccase genes and a small subunit of Lacc2 （sspoxa3） in different stages of fungal development were analyzed by real-time PCR. lacc6 and sspoxa3 are highly expressed throughout the growth and development stage, lacc12 is highly expressed during primordium differentiation and fruiting body formation, suggesting that lacc12 functions in fruiting, lacc4, lacc7 and laccll are highly expressed in primordium stage, indicating they are related with primordium differentiation, lacc2, lacc3 and lacc8 are relevant to fruiting body differentiation and maturation, with high expression during mature fruiting stage
