• Key message
  • The overexpression leads to a range of novel phenotypes, involving increased growth rate and altered plant architecture, suggesting that OsHDAC1 functions in the genome-wide programming of gene expression
  • Structure and expression of the rice class-I type histone deacetylase genesOsHDAC1-3:OsHDAC1overexpression in transgenic plants leads to increased growth rate and altered architecture
  • We have previously isolated a rice gene encoding a histone deacetylase, OsHDAC1, and observed that its transgenic overexpression increases seedling root growth
  • To identify the transcriptional repression events that occur as a result of OsHDAC1 overexpression (OsHDAC1(OE)), a global profiling of root-expressed genes was performed on OsHDAC1(OE) or HDAC inhibitor-treated non-transgenic (NT) roots, in comparison with untreated NT roots
  • We selected 39 genes that are induced and repressed in HDAC inhibitor-treated NT and OsHDAC1(OE) roots, compared with NT roots, respectively
  • The root phenotype of OsNAC6 knock-out seedlings was observed to be similar to that of the OsHDAC1(OE) seedlings
  • Conversely, the root phenotype of the OsNAC6 overexpressors was similar to that of the OsHDAC1 knock-out seedlings
  • These observations indicate that OsHDAC1 negatively regulates the OsNAC6 gene that primarily mediates the alteration in the root growth of the OsHDAC1(OE) seedlings
  • The histone deacetylase OsHDAC1 epigenetically regulates theOsNAC6gene that controls seedling root growth in rice
  • OsHDAC1 was expressed at similar levels in the leaves, roots, and callus cells, whereas OsHDAC2 and 3 were expressed in the roots and callus cells, but not in the leaves, exhibiting distinct tissue specificity
• Connection
  • OsHDAC1, OsNAC6~SNAC2, The histone deacetylase OsHDAC1 epigenetically regulates theOsNAC6gene that controls seedling root growth in rice, Interestingly, OsNAC6, a member of the NAM-ATAF-CUC (NAC) family, was identified as a key component of the OsHDAC1 regulon, and was found to be epigenetically repressed by OsHDAC1 overexpression
  • OsHDAC1, OsNAC6~SNAC2, The histone deacetylase OsHDAC1 epigenetically regulates theOsNAC6gene that controls seedling root growth in rice, The root phenotype of OsNAC6 knock-out seedlings was observed to be similar to that of the OsHDAC1(OE) seedlings

  • OsHDAC1, OsNAC6~SNAC2, The histone deacetylase OsHDAC1 epigenetically regulates theOsNAC6gene that controls seedling root growth in rice, Chromatin immunoprecipitation assays of the OsNAC6 promoter region using antibodies specific to acetylated histones H3 and H4 revealed that OsHDAC1 epigenetically represses the expression of OsNAC6 by deacetylating K9, K14 and K18 on H3 and K5, K12 and K16 on H4
