Rice grain width gene GW5L and application thereof

Abstract

The invention discloses a rice grain width gene GW5L and an application thereof, and provides an application of protein GW5L, a DNA molecule encoding the protein GW5L or a recombinant vector containing the DNA molecule encoding the protein GW5L in regulation of the grain shape of a plant. The gene GW5L is transferred into wild rice, and transgenic rice is obtained. Compared with recipient rice, the gene GW5L in the transgenic rice is overexpressed, the grain width of the rice is reduced substantially, and the grain length is increased significantly. A foundation is laid for cultivating transgenic plants with changed grain shapes.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to rice grain width genes GW5L Isolation of coding regions and their applications. Background technique [0002] Rice ( Oryza sativa L.) is an important food crop in the world, rice is the staple food of more than half of the world's population, and it is also the largest food crop in my country. For a long time, in order to solve the ration problem of 1.3 billion, my country's rice breeding has always focused on high yield and neglected quality improvement, resulting in the current situation of "high yield but not high quality" in my country's rice varieties. In recent years, with the rapid development of the market economy and the continuous improvement of people's living standards, the market's demand for high-quality rice has become increasingly strong, and people's requirements for the appearance of rice and the quality of cooking and eating are also increasing, especially in t...
