Genome-wide analysis and expression profiling of the heat shock transcription factor gene family in Physic Nut (Jatropha curcas L.).


ABSTRACT: The heat shock transcription factor (Hsf) family, identified as one of the important gene families, participates in plant development process and some stress response. So far, there have been no reports on the research of the Hsf transcription factors in physic nut. In this study, seventeen putative Hsf genes identified from physic nut genome. Phylogenetic analysis manifested these genes classified into three groups: A, B and C. Chromosomal location showed that they distributed eight out of eleven linkage groups. Expression profiling indicated that fourteen JcHsf genes highly expressed in different tissues except JcHsf1, JcHsf6 and JcHsf13. In addition, induction of six and twelve JcHsf genes noted against salt stress and drought stress, respectively, which demonstrated that the JcHsf genes are involved in abiotic stress responses. Our results contribute to a better understanding of the JcHsf gene family and further study of its function.
