Estimating the term…
An intelligent genetic breeding and seed production system for crop cross breeding and hybrid seed production are disclosed. The system comprises a GAT system carrier. The carrier comprises five functional element expression cassettes: a plant male fertility restoration genetic element expression cassette, used for restoring the male fertility of a recessive genic male sterile mutant; a plant pollen abortion genetic element expression cassette, used for clearing GAT-containing pollen and maintaining a heterozygous state or a hemizygous state of a GAT maintainer line; a chemical herbicide positive selection expression cassette, used for gene transformation and impurity removal and purification for the GAT maintainer line; a chemical herbicide negative selection expression cassette, used for clearing pollen and seed escape of a herbicide-sensitive GAT maintainer line and impurity removal and purification for a GAT sterile line; and a seed screening element expression cassette, used for mechanical sorting of seeds.
An intelligent genetic breeding and seed production system for crop cross breeding and seed production, called GAT system, characterized by comprising three lines of a plant recessive genic male sterile line, i.e., GAT sterile line, a recessive genic male sterile maintainer line, i.e., GAT maintainer line, and a common restorer line, wherein the plant is rice;
A vector for intelligent genetic breeding and seed production of the crop, called GAT vector, wherein the GAT vector is pC0308-MMMaauCK5400, pC0308-KhvMMaauMCK5400, pC0308-KhvMaauMCMK5400, pC0309-KhvMaauMCMK5400 and pC0307-KhvMaauMCMK5400;
