摘要：Heat shock transcription factors(Hsfs),
which acta simportant transcriptional regulatory proteins, play crucial roles in
plant developmental processes, and stress responses. Recently, the genome of the
shrub willow Salix suchowensis was fully
sequenced. In this study, a total of 27 non-redundant Hsf genes were identified from the S. suchowensis genome. Phylogenetic analysis revealed that the members
of the SsuHsf family can be divided into
three groups (class A, B, and C) based on their structural characteristics. Promoter
analysis indicated that the SsuHsfs promoters
included various cis-acting elements related
to hormone and/or stress responses. Furthermore, the expression profiles of 27 SsuHsfs were analyzed in different tissues
and under various stresses (heat, drought, salt, and ABA treatment) using RT-PCR.
The results demonstrated that the SsuHsfs
were involved in abiotic stress responses. Our results contribute to a better
understanding of the complexity of the SsuHsf
gene family, and will facilitate functional characterization in future studies.
