AbstractThe multigene familyWRKYis plant-specific transcription factors, which is involved in numerous aspects of plant growth and development. Here, we report a genome-wide search for the rubber treeWRKY(HbWRKY) genes and their expression profiles at various tissues including latexes. We also present a comprehensive overview of wholeHbWRKYgene family, including gene structure, chromosomal locations, conserved protein domains, gene duplications and phylogenetic inferences. We identify a total of 108 full-lengthHbWRKYgenes, which were classified into the three major subgroups. The genome-scale syntenic analysis showed that WGDs might have played a major role in the evolution of theHbWRKYgene family. Our further real-time reverse transcription-PCR (qRT-PCR) experiments validated that theHbWRKYgenes are divergently expressed and gene expression divergence seemingly existed among the duplicatedWRKYgenes, suggesting a fundamentally functional divergence of the duplicatedWRKYparalogs in rubber tree. We also investigated the gene expression profiling of theHbWRKYs under salt stress, to which the majority of genes differentially responded. This study acquires a new insight into the evolution of theHbWRKYs, which will help further functional characterization of theses candidate genes in rubber tree.
