Less and shrunken pollen 1（LSP1） encodes a member of the ABC

发布时间：2022-01-02 17:18

　　Pollen fertility is an agronomic trait that strongly influences rice yield. Recent studies have revealed that the development of the pollen wall is required for pollen fertility and is regulated by several genes. However, the mechanisms underlying pollen and pollen wall development in rice remain largely unknown. In the present study, a point mutation in a gene on chromosome 1 was identified that resulted in the production of less and shrunken pollen（LSP） and led to defects in pollen wall format...
