Method for inducing plants to bloom early by populus tomentosa sepallata (PtSEP) gene of poplar

Abstract

The invention discloses a method for inducing plants to bloom early by a populus tomentosa sepallata (PtSEP) gene of poplar. In the method, the total length of complementary deoxyribonucleic acid (cDNA) of the PtSEP gene, which is the target gene, of the poplar to construct an ultra-expression vector of the PtSEP gene, and the ultra-expression vector is transferred into a plant to advance the blossom time of the plant such as tobacco and the like. The early flowering induction of the plants and particularly flowers is performed by utilizing the transgenic technology, the period is short and the effectiveness is quick.

Description

technical field [0001] The invention relates to a method for inducing early flowering of plants, in particular to a method for inducing early flowering of plants using poplar PtSEP gene. Background technique [0002] The flowering decision process is the first stage of plant reproductive growth initiation, which directly controls the early or late of plant growth period, so it is closely related to plant products. Can allow its early flowering for flower plant, to produce the product that people need. Early flowering of some plants is beneficial to the growth of fruit, changing the growth cycle and breeding cycle, and it is possible for farmers to grow one season in a year. Delaying flowering of crops such as vegetables is beneficial for them to produce more leaves, because flowering consumes excess nutrients and energy. [0003] In the prior art, the flowering period of plants is generally regulated by flowering period regulation (such as plant hormones) and greenhouse te...

Problems solved by technology

[0005] The control ability of the flowering regulation method is limited, and the hybridization method needs corresponding parental materials, and the cycle is long and the breeding process is complicated
