  • Method for modulating the number of archesporial cells in a developing anther
    Patent number: 9516824
    Abstract: Certain embodiments provide a method of altering the number of archesporial cells in a developing anther of a plant in certain embodiments, the method comprises exposing the anther to redox-modulatory conditions prior to differentiation of germline cells in the anther, thereby changing the redox potential of cells in the anther and altering the number of archesporial cells in the anther. This method may be employed to increase or decrease the number of archesporial cells in a developing anther, and may be employed to produce male sterile plants.

  • REGULATORY NON-CODING RNAS AS DETERMINANTS OF MALE STERILITY IN GRASSES AND OTHER MONOCOTYLEDONOUS PLANTS
    Publication number: 20160251679
    Abstract: A method for controlling male fertility of a plant comprises regulating a biological activity of a phasiRNA in a male reproductive organ of the plant. The phasiRNA is selected from the group consisting of 21-nt phasiRNAs and 24-nt phasiRNAs. The male fertility of the plant is thereby increased or decreased. Preferably, the plant is a monocotyledon and becomes male sterile. The resulting male sterile plant and its uses are also provided.
