Abstract WD-repeat protein, containing WD-40 motif, also known as WD40 repeat protein, which plays an essential regulating role during the abiotic stress response of plants. In this study, it was found that a kenaf (Hibiscus cannabinus) transcriptome unigene which was highly similar to the WD40 gene, and then designed the primers to carry out reverse transcription PCR amplification and obtained HcWD40-1(GenBank No.: KX711617) cDNA sequence by sanger sequencing. Bioinformatics analysis showed that the gene open reading frame was 1 356 bp, encoding 451 amino acids, and containing 7 typical WD40 domains. qRT-PCR analysis showed that HcWD40-1 gene was induced by salt and drought stress, and was induced by abscisic acid (ABA) and methyl jasmonate (MeJA). The results suggested that the HcWD40-1 gene was a key hub gene for ABA and MeJA signaling pathways, salt and drought stress responses. The results of the study provide basic data for the study of salt-tolerant, drought-resistant on ABA signal regulation network and MeJA signal regulation network of kenaf.
