Genome-wide identification and characterization of cacao WRKY transcription factors and analysis of their expression in response to witches' broom disease.

ABSTRACT: Transcriptional regulation, led by transcription factors (TFs) such as those of the WRKY family, is a mechanism used by the organism to enhance or repress gene expression in response to stimuli. Here, we report on the genome-wide analysis of the Theobroma cacao WRKY TF family and also investigate the expression of WRKY genes in cacao infected by the fungus Moniliophthora perniciosa. In the cacao genome, 61 non-redundant WRKY sequences were found and classified in three groups (I to III) according to the WRKY and zinc-finger motif types. The 61 putative WRKY sequences were distributed on the 10 cacao chromosomes and 24 of them came from duplication events. The sequences were phylogenetically organized according to the general WRKY groups. The phylogenetic analysis revealed that subgroups II
