| Research Abstract |
In plants, interspecific cross often display hybrid incompatibility in the endosperm. We speculated that epigenetic mechanisms such as genomic imprinting contribute to this phenomena (GGS 2007). In this project, we identified the fact that SSRP1, know as a component of FACT histone chaperon component, is required for DNA demethylation and activation of imprinted genes (Dev. Cell 2011). We also investigated endosperm development in the hybrid endosperm in rice, and identified that developmental alteration is the cause of hybrid incompatibility (Plant J. 2011).
