Genome wide identification and expression analysis of pepper C₂H₂ zinc finger transcription factors in response to anthracnose pathogen Colletotrichum truncatum.

ABSTRACT: Although, the C₂H₂ zinc finger (ZF) family of plant transcription factors have been implicated in multiple biological processes, they are yet to be characterized in the economically important chilli pepper (Capsicum annuum). In this study, a total of 79 C₂H₂ ZF genes were identified in the pepper genome. Phylogenetic analysis categorized the pepper C₂H₂ ZF (CaZF) members into five subfamilies each with unique conserved domains and functions. Genomic organization revealed that CaZF genes have variable number of introns consistent with the characteristics defined by the evolutionary analysis. Segmental duplication-based purifying selection contributed to the expansion of CaZF genes in pepper. Additionally, 11 CaZF genes
