Molecular growth regulator for improving flowering ability of ornamental plants under weak light and application of molecular growth regulator

The invention discloses a molecular regulator for improving flowering ability of plants under weak light and related application. According to the present invention, the lotus NlTPS1 gene, the geminivirus vector, the virus infection enhancer and other components are utilized to prepare the universal shade-tolerant molecule regulator in ornamental plants, and the shade-tolerant molecule regulator comprises an overexpression vector IL60s-1-NlTPS1, an auxiliary virus vector IL60s-2, polybrene, glucose, dimethyl sulfoxide, magnesium chloride and deionized water. According to the invention, the flowering ability and growth performance of ornamental plants under the shading condition can be improved, and the flowering of the plants is promoted. The gene expression regulation generated by the plant shade-tolerant molecule regulator disclosed by the invention is not inherited, is efficient and specific, is not limited by transgenosis regulations and policies, and belongs to a green and safe method for improving the f
