The invention relates to a botanic vegetative growth maintenance
gene system, the establishment of a vegetative growth maintenance
plant, and a method for utilizing the infinite growth capacity of seed plants. The vegetative growth maintenance
gene system comprises a
promoter, a cellular
lethal factor gene, and a gene device which is arranged when necessary and is used for limiting or eliminating the
toxicity of non-target cells of the vegetative growth maintenance gene
system; and the utilization of the infinite growth capacity of the seed plants is that the gene system is integrated into a botanic nuclear
genome and accurately and correctly begins to perform expression according to given tissues and organs and the specificities of developmental stages. The vegetative growth maintenance gene system can effectively remove cells of reproductive meristems which appear in vegetative apical meristems, and prevent the vegetative meristems from being differentiated, so that a novel, high-yield and high-quality vegetative
mass utilization
plant, namely the vegetative growth maintenance
plant is created; and the vegetative growth maintenance gene system can be applied to all vegetative
mass utilization plants, so that the
growth speed, production efficiency and yield of vegetative masses of the vegetative
mass utilization plants are greatly improved on the original basis.
