The rice Os02g0762400 was reported as KRP1 in 2006 [1] by researchers from Belgium.

Annotated Information
Gene Symbol
- Os02g0762400 <=> KRP1,OsiICK1, Orysa;KRP1, OrysaICK1, Orysa;ICK1, CDKI
Function
- Kip-related proteins (KRPs) play a major role in the regulation of the plant cell cycle.
- KRP1 plays an important role in the exit from the mitotic cell cycle during rice grain
formation.
Phenotypic analysis
- Phenotypic analysis revealed that overexpressed KRP1 reduced cell production during leaf development.
- The reduced cell production in the leaf meristem was partly compensated by an increased cell size, demonstrating the existence of a compensatory mechanism in monocot species by which growth rate is less reduced than cell production, through cell expansion.
- Furthermore, KRP1 overexpression dramatically reduced seed filling. Sectioning through the overex-pressed KRP1 seeds showed that KRP overproduction disturbed the production of endosperm cells. The decrease in the number of fully formed seeds was accompanied by a drop in the endoreduplication of endosperm cells, pointing toward a role of KRP1 in connecting endocycle with endosperm development.
