Abstract

The invention discloses a rice male sterility gene PMP1 and application thereof, the rice male reproductive development is controlled by adopting a genetic engineering means, a new rice male sterility line is generated by mutating a protein coded by the PMP1 gene or inhibiting the expression of the protein, and the male sterility line generates no pollen at the reproductive growth stage. However, the pistil can be normally pollinated and fruited, so that the rice male sterile line has very important application in agricultural production.
