Abstract: Provided are a phosphorus-efficient and high-yield gene of crops, and an application thereof. It is first disclosed that a PHO1;2 gene has a regulating function on filling of crop kernels. Up-regulating the expression of the gene in crops can significantly promote filling of the crop kernels, increase the kernel weight of the crop kernels, the kernels per spike, the tiller number and the kernel thickness, and/or promote thickening of the crops. The PHO1;2 gene plays a two-way phosphorus transport effect which mainly conveys phosphorus to the extracellular domain, can regulate intracellular phosphorus accumulation, increase the utilization rate of phosphorus in crops, and improve the duration of crops to a low-phosphorus environment.

Abstract: Novel crop grain filling genes (GIF1) and the applications thereof are presented in the invention. The GIF1 genes can be applied to control grain filling, enhance crop yield or quality, or improve disease resistance or storage stability of crop grains. A method for improving crops is also presented in the invention. The GIF1 genes shows valuable potentials in controlling crop yield, quality, storage, and resistance to diseases.

Abstract: Provided are a high temperature resistant plant gene and use thereof. The high temperature resistant gene can not only be used to modify she high temperature resistant property of a plant, but also has the functions of promoting plant growth, improving plant yield and increasing plant biomass and the like. The gene can also be utilized in the field of plant breeding to cultivate fine seed strain.

Abstract: Provided are a crop height regulatory gene from Arabidopsis thaliana, expression regulatory sequences thereof and uses thereof. The crop regulatory gene can be used to regulate the plant height, volume, tiller, yield, flower organ size, or seed size of crops.
