Gene Symbol
- Os05g0446000 <=> DNG701,OsDNG701
Function
Fig. 1. Enzymatic activity of DNG701 on 5-meC-containing DNA substrates in vitro. [1].
- DNG701 encodes a large (1,812 amino acid residues) DNA glycosylase domain protein.
- Rice DNG701 is a 5-meC DNA glycosylase/lyase responsible for the demethylation of Tos17 and this DNA demethylase plays a critical role in promoting Tos17 transposition in rice calli.
Mutation
- Knockout or knockdown of DNG701 in rice plants led to DNA hypermethylation and reduced expression of the retrotransposon Tos17. Tos17 showed less transposition in calli derived from dng701 knockout mutant seeds compared with that in wild-type calli.
Overexpression
- Overexpression of DNG701 in both rice calli and transgenic plants substantially reduced DNA methylation levels of Tos17 and enhanced its expression. The overexpression also led to more frequent transposition of Tos17 in calli.
Expression
