Annotated Information
Function
- It belongs to Heat stress transcription factors (Hsfs),Heat stress transcription factors (Hsfs) are the central regulators of defense response to heat stress.Hsfs diversify in their biological functions [1]. HsfA members are capable of transcriptional activation,while HsfB members act as repressors or as co-activators (e.g., HsfB1) of HsfA members [2]. However,AtHsfA4 activity was reported to be repressed by AtHsf5, which belongs to class A Hsfs. Overexpression of Hsf genes in transgenic plants resulted in an up-regulation of heatstress-associated genes and an enhancement of thermotolerance, whereas the down-regulation of Hsf genes leads to a reduction in the thermotolerance[3][4].
- AtHsfA9 is involved in seed development and controlled by seed-specific transcription factor abscisic acid-insensitive 3 (ABI3).Further studies to elucidate the functions of the other members in the subfamily may also have potential for the development of transgenic plants with improved stress tolerance.
Expression
- Expression patterns of OsHsfs:The number of ESTs for a specific gene in a cDNA library is considered to be proportional to the transcript abundance of the mRNA.OsHsfs were expressed at a higher level in panicle and flower than in other tissues.
- The transcription of OsHsfA9 was up-regulated by both HS and H2O2 treatments in a similar manner.
- In Arabidopsis, the heat stress-induced H2O2 is required for effective expression of heat shock genes.
Evolution
- Phylogenetic analysis of OsHsfs indicates that the classes A, B and C Hsfs formed three individual clusters. Furthermore, the class A Hsfs were divided into two sub-clusters In a previous study, the N-terminal part and C-terminal part of DBD and HR-A/B regions were used separately to draw phylogenetic trees.Although most proteins fixed their positions in the different phylogenetic trees, a few Hsfs changed their positions.Similar phenomenonwas also observed on the OsHsfs . A more convinced relationship of the Hsfs was revealed by combining the DBD, HR-A/B, and the flexible linker between DBD and HR-A/B.
