TRANSGENIC PLANT MALE STERILITY

摘要

The invention relates to a reversible transgenic plant male sterility system wherein the male sterility is induced by amiRNA and a reversible transgenic plant male sterility system comprising a male sterility construct comprising an isolated nucleic acid encoding a precursor amiRNA encoding an amiRNA targeted to a gene involved in pollen development, and a male fertility restorer construct comprising an isolated nucleic acid encoding a mutated copy of the gene involved in pollen development, or multiple copies of said gene involved in pollen development, or a single copy of said gene involved in pollen development under the control of a strong promoter.
