Genome-Wide Analysis of the Gene Family under Abiotic Stress and Characterization of the Gene.

Heat shock factors (Hsfs) play a crucial role in plant defense processes. However, the distribution and functional characteristics of Hsf genes in the relict plant are still unclear. In this study, a total of 19 were identified and divided into three separate subgroups, comprising 10 , 7 , and 2 genes, respectively, based on their phylogenetic tree and the presence/absence of conserved protein domains.
