盐和干旱胁迫下红麻HcWD40-1基因的克隆及表达特征
Cloning and Expression Characteristics of HcWD40-1 Gene Under Salt and Drought Stress in Kenaf(Hibiscus cannabinus)
摘要
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.关键词
