Identification and Bioinformatics Analysis of Hsf Gene Family in Euscaphis konishii
The Euscaphis konishii is small evergreen trees with high medicinal and ornamental value.Heat shock transcription factor(Hsf)acts as activators of heat shock protein(Hsp)and plays multiple roles in response to environmental stress and plant development.Although the Hsf gene family has been identified in many plants,it is unknown in E.konishii.This study was conducted to identify and bioinformatically analyze the E.konishii Hsf gene family.The results showed that there were 22 Hsf family genes in E.konishii,which could be classified into three groups based on their protein structures and phylogenetic characteristics.Gene structure and structural domain analysis indicated that Hsf genes were relatively conserved during evolution.Analysis of cis-acting elements showed that EkHsf genes play important roles in the response to various stresses in E.konishii.The results of synteny analysis indicated that fragment replication events played an important role in the evolution and expansion of the Hsf gene family in E.konishii.The expression of EkHsf genes in different tissues and developmental stages showed tissue specificity.Finally,EkHsf-B4b and EkHsf-B1b were identified by co-expression analysis as potential regulators of anthocyanin synthesis in E.konishii.The results of this study provide a scientific basis for further study on the biological function of Hsf gene of E.konishii.
