Abstract

The invention discloses rice root development and stress resistance related OsSAUR11 genes which are isolated and cloned from rice DNA fragments. Protein encoded by the genes contains SAUR family conserved structural domains. The rice root development and stress resistance related OsSAUR11 genes belong to the field of rice cloning genes. The sequence of the OsSAUR11 genes is as shown in followingsequences: a DNA sequence as shown in SEQ ID NO: 1, a DNA sequence at least 90% homologous to SEQ ID NO: 1 and a subfragment functionally equivalent to the sequence as shown in SEQ ID NO: 1; the expression of the OsSAUR11 genes is the root development and stress resistance. The rice root development and stress resistance related OsSAUR11 genes disclosed by the invention have the beneficial effectsthat the OsSAUR11 genes are in inducible expression of osmotic stress, abscisic acid and auxins, and overexpression of OsSAUR11 can enhance the deep root ratio of rice and enhance drought resistanceof the rice, is related to rice stress resistance, and has obvious response to adverse environments, thereby being applied to plant drought-resistance breeding, improving the root configuration and enhancing plant stress resistance.

Description

technical field

[0001] The invention relates to a gene related to rice root growth and stress resistance, in particular to a new rice deep root growth and stress resistance related gene OsSAUR11 and its application, belonging to the field of genetic engineering. Background technique

[0002] Drought and water shortage are one of the important factors causing the reduction of global food production. Drought stress seriously affects plant growth and development, and even causes plant death. Rice is one of the important food crops. Rice needs 65% of the water used for agricultural irrigation. Modern biological technology is used to study the physiological and biochemical reactions of plant drought resistance, clone important drought resistance genes, and then transfer them to plants to cultivate stress-resistant New crop varieties, especially cultivating new water-saving and drought-resistant rice varieties are an effective way to alleviate the pressure on food production brou...
