Gene Details:

  • Gene ID:
  • Gene Symbol: TaEXPA1
  • Gene Name: Expansin gene1
  • Genome:
  • Species: Triticum aestivum

Functional Descriptions:

  • Expansin genes play important roles in the regulation of cell size, as well as organ size. We found that all three TaEXPA1 homoeologs were silenced in seedling roots.
  • Chromatin immunoprecipitation assays revealed that the transcriptional silencing of three TaEXPA1 homoeologs in roots was correlated with an increased level of H3K9 dimethylation and decreased levels of H3K4 trimethylation and H3K9 acetylation.
  • Reactivation of TaEXPA1-A and TaEXPA1-D expression in leaves was correlated with increased levels of H3K4 trimethylation and H3K9 acetylation, and decreased levels of H3K9 dimethylation in their promoters, respectively.
  • We demonstrated that epigenetic modifications contribute to the expression divergence of three TaEXPA1 homoeologs during wheat development.
