Abstract

The invention belongs to the technical fields of molecular biology and genomic engineering, in particular to an EADT1 gene capable of improving drought resistance of rice in a growth period, a coding sequence and application. The invention relates to a coding sequence of a plant lipid transfer protein gene EADT1 expressed in the rice, and the coding sequence mainly has effects of improving the drought resistance of the rice in the growth period (including but not limited to the growth period) and improving the maturing rate of the rice. The invention also discloses a recombinant vector comprising the gene sequence, and a transgenic plant transformed by the vector. The gene is subjected to transformation expression in a plant, the maturing rate of the transgenic rice under drought stress can be improved, and the yield loss of crops in adverse situations such as drought is reduced.

Description

technical field

[0001] The invention belongs to the technical fields of molecular biology and genetic engineering, in particular to a lipid transfer protein expressed in rice EADT1 Cloning of genes, construction of transgenic vectors and application in improving drought tolerance and seed setting rate of rice. Background technique

[0002] Rice is the most important food crop in my country, and it is also the crop that uses the most water in agricultural production. Drought has seriously affected the yield of rice. How to reduce the dependence of rice on water and make it have the characteristics of water saving and drought resistance is of great significance to my country's food, water and ecological security. An important determinant of yield is the seed setting rate of rice at the flowering stage. Rice has different tolerance to drought at different developmental stages (Saini & Lalonde, 1998; Yang & Zhang, 2006). When there is a lack of water in the vegetative period,...
