Gene Symbol

  • Os09g0442700 <=> OsDDM1a

Function

  • OsDDM1 genes function to silence endogenous loci including those related to retrotransposons in the rice genome, however, their roles on transposition of active transposons in the genome remains unknown.
  • Hypomethylation induced by the antisense OsDDM1 disturbs normal development.
  • Transgenic rice lines expressing OsDDM1a cDNA in antisense orientation exhibited the genomic DNA hypomethylation in repeated sequences similar to the pattern observed in Arabidopsis ddm1 mutants.

Expression

  • OsDDM1a and OsDDM1b are expressed during development with slight variations among various tissues, suggesting that there might be functional divergence of these two genes (Fig. 1c).
