Abstract

 

Histone deacetylases (HDACs) plays critical roles in the regulation of chromatin structure and gene expression. HDACs are highly conserved in yeast, animals and plants, suggesting a fundamental mechanism in transcriptional regulation. Sequence characterization and phylogenetic relationships reveals the existence of several distinct families. In plants, the genome-wide identification of HDACs has been performed in several species. These genes are emerging as crucial players in all aspects of plant development, including embryogenesis, abaxial/adaxial polarity determination, flowering and senescence as well as responses to day length and environmental stresses. In this study, we analysed the HDACs from Oryza sativa and Arabidopsis thaliana. This analysis revealed the presence of 21 and 82 genes coding for putative HDACs in rice and arabidopsis, respectively and found out Poly amphipathic helix domain (PAH) and HDAC interact domains are present in these genes. In this work, we analysed the HDAC families and classified based on their structure.

 

Key words: Histone deacetylases, Oryza sativa, Arabidopsis thaliana, poly amphipathic helix domain (PAH) domain, Histone deacetylases (HDACs) domain.
