A C 2 H 2 Zinc Finger Protein PlCZF1 Is Necessary for Oospore Development and Virulence in Peronophythora litchii

C H zinc finger is one of the most common motifs found in the transcription factors (TFs) in eukaryotes organisms, which have a broad range of functions, such as regulation of growth and development, stress tolerance and pathogenicity. Here, was identified to encode a C H zinc finger in the litchi d...

Summary:C H zinc finger is one of the most common motifs found in the transcription factors (TFs) in eukaryotes organisms, which have a broad range of functions, such as regulation of growth and development, stress tolerance and pathogenicity. Here, was identified to encode a C H zinc finger in the litchi downy blight pathogen . is conserved in and species. In , is highly expressed in sexual developmental and early infection stages. We generated mutants using the CRISPR/Cas9 method. Compared with the wild type, the mutants showed no significant difference in vegetative growth and asexual reproduction, but were defective in oospore development and virulence. Further experiments revealed that the transcription of , and three laccase encoding genes were down-regulated in the mutant. Our results demonstrated that is a vital regulator for sexual development and pathogenesis in
