Function
Histone deacetylases (HDAC) are important in plant gene expression. The expression of the gene OsHDAC702/HDAC1 is regulated by gene OsNAC6 and the gene OsNAC6 controls the growth of Rice seedlings roots. Over-expression of gene HDAC702/HDAC1 enhances root growth.
Expression
The length of OsHDAC701/HDAC1 cDNA is 1859bp, OsHDAC701/HDAC1 contains seven exons and encoding a 518 amino acid composition of protein products. Similar to other HDAC genes, HDAC702 shows a relatively high level in developing panicles and calli. The gene is clearly repressed by drought and salt. HDA702, HDA710 and HDA703 correspond respectively to OsHDAC1–3. Phylogenetic analysis indicates that the 3 rice genes belong to the same clade as AtHD1/HDA19, with HDA702 as the closest homolog of AtHD1/HDA19. AtHD1/HDA19 is the most studied HDAC gene in Arabidopsis. It is shown that over-expression of HDA702/HDAC1enhances root growth. Based on the RT-PCR of the HDAC702 gene, the gene was detected in leaves, stems, and roots, however, the levels of accumulation differed among different organs. To investigate the expression pattern of HDAC gene in response to environmental stress conditions, RT-PCR was conducted using total RNA isolated from leaves of seven day-old rice seedlings that were subjected to cold (4℃), mannitol and salt (NaCl) treatment. After these kinds of treatments, the expression of HDAC702 was increased.(Dao-Xiu Zhou et al.,2009)
Evolution
Phylogenetic analysis indicates that the HDA702, HDA710 and HDA703 rice genes belong to the same clade as AtHD1/HDA19, with HDA702 as the closest homolog of AtHD1/HDA19. AtHD1/HDA19 is the most studied HDAC gene in Arabidopsis.
