Annotated Information

Function

Please input function information here.

Heat stress transcription factors (Hsfs) are the central regulators of defense response to heat stress. Plant Hsf gene family is divided into three classes, HsfA, HsfB, and HsfC, according to their protein structures[1]. HsfB1 is one gene of the HsfB which consists of 8 genes. plant Hsfs diversify in their biological functions[2][3]. HsfA members are capable of transcriptional activation, while HsfB members act as repressors or as co-activators (e.g., HsfB1) of HsfA members. Overexpression of Hsf genes in transgenic plants resulted in an up-regulation of heat stress-associated genes and an enhancement of thermotolerance, whereas the down-regulation of Hsf genes leads to a reduction in the thermotolerance[4][5]. In addition to control of heat stress response, Hsfs have also been reported to be involved in the defense response to pathogen attack, oxidative stress, heavy metals, dehydration and salinity, and in certain processes of development and differentiation[6].

Expression

Please input expression information here.

Chuang wang[7] detect the expression patterns of OsHsfs in rice. They find the majority of OsHsf genes have a low to moderate level in most tissues, while some display a tissue-specific manner (Fig.1). For example HsfB1, than other genes has a relative heavy level in the tissues of root and seed. Chuang wang also studys the Cis-acting elements in OsHsf promoters. They find 9 different Cis-acting elements in total. One of the Cis-acting element，ARE and GC-motif involved in the anaerobic induction, has a high number of 4 in the HsfB1. We can suppose that the high level of HsfB1 in seed and root and the high level of ARE and GC-motif are adaptive to the environment for rice.

Evolution

Please input evolution information here.

You can also add sub-section(s) at will.

Chuang wang[7] construct neighbor-joining phylogenetic trees(fig.2) to determine the phylogenetic relationship among the OsHsfs. AtHsf stand for Arabidopsis Hsf, which is used to classify rice Hsfs.
