摘要： The C2H2-type zinc finger proteins (C2H2-ZFPs) regulate various developmental processes and abiotic stress responses in eukaryotes. Yet, a comprehensive analysis of these transcription factors which could be used to find candidate genes related to the control the development and abiotic stress tolerance has not been performed in Pleurotus ostreatus. To fill this knowledge gap, 18 C2H2-ZFs were identified in the P. ostreatus genome. Phylogenetic analysis indicated that these proteins have dissimilar amino acid sequences. In addition, these proteins had variable protein characteristics, gene intron-exon structures, and motif compositions. The expression patterns of PoC2H2-ZFs in mycelia, primordia, and young and mature fruiting bodies were investigated using qRT-PCR. The expression of some PoC2H2-ZFs is regulated by auxin and cytokinin. Moreover, members of PoC2H2-ZFs expression levels are changed dramatically under heat and cold stress, suggesting that these genes may participate in abiotic stress responses. These findings could be used to study the role of P. ostreatus-derived C2H2-ZFs in development and stress tolerance.
