HDT701, a histone H4 deacetylase, negatively regulates plant innate immunity by modulating histone H4 acetylation of defense-related genes in rice - PubMed
ROS Generation, Defense Gene Expression, and Histone Acetylation Levels in the HDT701 OX and RNAi Plants. (A) ROS level in HDT701 RNAi plants after flg22 treatment. Error bars indicate the
sd(n = 3). NPB, Nipponbare. (B) ROS level in HDT701 RNAi plants after chitin treatment. Error bars indicate the
sd(n = 3). (C) Time-course transcription analysis of CEBiP in Nipponbare (NPB), HDT701 OX, and RNAi plants after chitin treatment. Error bars indicate the
sdfrom three biological replicates (n = 3), and asterisks indicate statistically significant differences compared with Nipponbare (t test, *P < 0.05, **P < 0.01). (D) Time-course transcription analysis of FLS2 in Nipponbare, HDT701 OX, and RNAi plants after flg22 treatment. Error bars indicate the
sdfrom three biological replicates (n = 3), and asterisks indicate statistically significant differences compared with Nipponbare or between the two comparisons marked with brackets (t test, *P < 0.05, **P < 0.01). (E) Time-course transcription analysis of SGT1 in Nipponbare, HDT701 OX, and RNAi plants after chitin treatment. Error bars indicate the
sdfrom three biological replicates (n = 3), and asterisks indicate statistically significant differences compared with Nipponbare (t test, *P < 0.05, **P < 0.01). (F) to (H) Time-course histone H4 acetylation level of CEBiP, FLS2, and SGT1 in Nipponbare, HDT701 OX, and RNAi plants after chitin ([F] and [H]) and flg22 (G) treatments. Diagrams of the CEBiP, FLS2, and SGT1 gene structures are shown above their respective ChIP analysis panels, in which the gray boxes indicate exons, white boxes indicate UTRs, the arrow shows translation start point, the thick black lines between gray boxes indicate introns, and the letter P, together with the short black lines, indicate PCR fragments that correspond to the promoter regions. Error bars indicate the
sdfrom three biological replicates (n = 3), and asterisks indicate statistically significant differences compared with Nipponbare or between the two comparisons marked with brackets (t test, *P < 0.05, **P < 0.01).
