pal1 and pal2 are involved in the development of P. ostreatus. a Developmental stages (mycelia, primordia and fruiting body) in the life cycle of the WT, OE and RNAi strains. b and c The growth rate of the pal mutants. d and e qPCR analysis of pal expression in tested strains at different development stages (mycelia, primordia, fruiting body and spores). The relative abundances of the transcripts at different stages were normalized by comparison with that observed in mycelia in the WT strain (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)
