摘要:
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.
摘要:
A method for generating a phased siRNA (phasiRNA) in a plant cell comprises introducing into the plant cell an effective amount of a microRNA (miRNA). A transcript of a NB-LRR encoding gene may be cleaved in the plant cell. Resistance of the plant to a microbe may be reduced. The plant may enter a symbiotic interaction with a microbe. Nodulation in the plant may be improved. Related compositions are provided.
