The expression of pal during different developmental stages and different parts of P. ostreatus fruiting bodies. a qPCR analysis of pal1 expression in WT strain during different cultivation stages. b qPCR analysis of pal2. The relative abundances of the WT transcript levels at different stages were normalized by comparison with that observed in the mycelium stage (relative transcript level = 1). c The expression of pal1 in four parts of the P. ostreatus fruiting body. d qPCR analysis of pal2 expression. The relative abundances of the transcript levels in the WT strain in the different parts of the fruiting body were normalized by comparison with that observed in the fruiting body (relative transcript level = 1). The values are the means ± SE of three independent experiments. Different letters indicate significant differences between the strains (P < 0.05, according to Tukey’s test)
