Contents
Annotated Information
Gene Symbol
- Os04g0531100 <=> OsPBP1
Function
- OsPBP1 is a novel functional C2-domain phospholipids-binding protein that is required for pollen fertility likely by regulating Ca21 and phospholipid signaling pathways.
- OsPBP1 is a single copy gene and preferentially expressed in pistil and pollen but downregulated by pollination.
- OsPBP1 had a calcium concentration-dependent phospholipid-binding activity and was localized mainly in cytoplasm and nucleus, but translocated onto the plasma membrane in response to an intracellular Ca21 increase.
- OsPBP1 protein was localized in a region peripheral to pollen wall and vesicles of elongating pollen tube, and its repressed expression reduced substantially this association and led to alteration of microfilament polymerization during pollen germination.
Mutant
- Pollen grains of antisense OsPBP1 transgenic lines were largely nonviable, germinated poorly in vitro and of low fertility
Labs working on this gene
- Institute of Genetics and Developmental Biology, Chinese Academy of Sciences and National Centre for Plant Gene Research, Beijing 100190, China
- Graduate School of Chinese Academy of Sciences, Beijing 100049, China
