Os06g0136900

The rice gene Os06g0136900 was reported as dp1 in 2011 by researchers from China.

Annotated Information

Gene Symbol

• Os06g0136900 <=> DP1,OSDP1

Function

• DP1 gene encodes a nuclear-localized AT-hook DNA binding protein, suggesting a grass-specific role of chromatin architecture modification in flower development.
• The researchers further found that SDP1/REP1 is downstreamly regulated by DP1.

Mutation

• The depressed palea1 (dp1) mutants show a primary defect in the main structure of palea, implying that palea is a fusion between the main structure and marginal tissues on both sides. The sterile lemma at the palea side is occasionally elongated in dp1 mutants. In addition, we found a floral organ number increase in dp1 mutants at low penetration.
