Embodiment 1

[0079] Example 1. Utilizing growth-associated protein genes to cultivate growth-increased transgenic Arabidopsis plants

[0080] This example provides four soybean Williams 82 (Haun, W.J., Hyten, D.L., Xu, W.W., Gerhardt, D.J., Albert, T.J., Richmond, T., Jeddeloh, J.A., Jia, G.F., Springer, N.M., Vance,C.P.&Stupar,R.M.(2011).The Composition and Origins of Genomic Variation among Individuals of the Soybean Reference Cultivar Williams 82.Plant Physiology 155,645-655. National Germplasm Bank Number: I2A12645, Uniform Number: WDD00587) The genes are growth-related protein GRP1 gene, growth-related protein GRP2 gene, growth-related protein GRP3 gene and growth-related protein GRP4 gene.

[0081] Prepare the DNA molecule shown in Sequence 2 in the sequence listing (i.e. growth-related protein GRP1 gene, referred to as GRP1 gene), the DNA molecule shown in Sequence 2 encodes the protein shown in Sequence 1 (i.e. growth-related protein GRP1, referred to as GRP1 protein).

Abstract

The invention discloses application of a growth-related protein GRP4 in regulation of plant growth. The growth-related protein GRP4 provided in the invention is a protein as shown in (a) or (b), wherein (a) refers to a protein composed of an amino acid sequence as shown in a sequence 7 in a sequence table, and b) refers to a protein which has same protein functions and is obtained by subjecting the amino acid sequence as shown in the sequence 7 in the sequence table to substitution and/or deletion and/or addition of one or more amino acid residues. Experimental results prove that the growth-related protein GRP4 and a coding gene thereof can promote vegetative growth and reproductive growth of plants and can be used for regulating the vegetative growth and reproductive growth of plants or cultivating transgenic plants.

Description

technical field [0001] The invention relates to the application of growth-related protein GRP4 in regulating plant growth in the field of biotechnology. Background technique [0002] The lodging problem and sensitive photoperiod response have always been the main problems that plague the high and stable yield of plants. Lodging occurs during the reproductive growth of plants with higher yield loss. The introduction of species between different latitudes will cause the flowering period and maturity period of plants to be advanced or delayed due to the change of sunshine length, which will cause the yield of plants to decrease. Therefore, there is an urgent need to adopt molecular breeding methods to regulate the plant type and photoperiod response sensitivity of plants through the introduction of exogenous genes or genetic manipulation of internal genes, so as to speed up the breeding process of lodging-resistant and wide-adapted plants. Contents of the invention [0003]...
