 * Overexpression of '''''HDT701''''' in transgenic rice leads to decreased levels of histone H4 acetylation and enhanced susceptibility to the rice pathogens M. oryzae and Xanthomonas oryzae pv oryzae (Xoo).
-* By contrast, silencing of HDT701 in transgenic rice causes elevated levels of histone H4 acetylation and elevated transcription of pattern recognition receptor (PRR) and defense-related genes, increased generation of reactive oxygen species after pathogen-associated molecular pattern elicitor treatment, as well as enhanced resistance to both M. oryzae and Xoo.

-OsHDT1(Os05g0597100)，is a histone deacetylase gene, that is involed in flowering time control and innate immunity in rice.
+The rice '''''Os05g0597100''''' was reported as '''''HDT701''''' in 2012 <ref name="ref1" /> by researchers from USA and China.
 ==Annotated Information==
 ===Function===
-OsHDT1 function in histone deacetylation[1]:
+* '''''HDT701''''' is a member of the plant-specific HD2 subfamily of HDACsencodes which a Histone H4 Deacetylase.
-OsHDT1 may be involved in histone deacetylation on a subset of genes, as over-expression of OsHDT1 led to decreases of histone acetylation on flowering repressor genes in both parent and hybrid backgrounds. Increased OsHDT1 promoted deacetylation that correlated with the repression of OsGI and Hd1 and early flowering in the hybrid. The effect of OsHDT1 seemed to occur at a higher acetylation phase of target genes, suggesting that OsHDT1 might be involved in circadian oscillation of histone acetylation and gene expression.
+* '''''HDT701''''' negatively regulates innate immunity by modulating the levels of histone H4 acetylation of PRR and defense-related genes in rice.
 ===Expression===
+* Transcription of '''''HDT701''''' is increased in the compatible reaction and decreased in the incompatible reaction after infection by the fungal pathogen Magnaporthe oryzae.
-Rice OsHDT belongs to the plant specific class of HDAC, the expression of which displays a circadian rhythm.
+* '''''HDT701''''' can bind to defense-related genes to regulate their expression.
 ===Evolution===
-During the long history of rice evolution, adaptation, selection and domestication, closely related rice species, subspecies and varieties may have developed significant epigenetic variation contributing to variation in adaptation and agronomic traits, which remains to be exploited in a perspective to identify agronomically interesting epialleles.
+* Overexpression of '''''HDT701''''' in transgenic rice leads to decreased levels of histone H4 acetylation and enhanced susceptibility to the rice pathogens M. oryzae and Xanthomonas oryzae pv oryzae (Xoo).
