Rice waterlogging stress response RS1 gene and application thereof

Abstract

Disclosed is a rice waterlogging stress response RS1 gene. The rice waterlogging stress response RS1 gene is characterized in that a DNA sequence of the RS1 gene is shown as SEQ ID NO:1 in a sequence table, and an amino acid sequence table of coded protein of the rice waterlogging stress response RS1 gene is shown as SEQ ID NO:2. The rice waterlogging stress response RS1 gene has the advantages that a ubi promoter is selected to drive the RS1 gene, so that waterlogging tolerance of rice is improved remarkably by an over-expressed transgenic line, waterlogging tolerant effect is obvious, and in a waterlogging environment, the RS1 gene can obviously improve waterlogging tolerance of the rice and guarantee high yield and stable yield of the rice; the RS1 gene is from the rice, so that worry, of people, about food safety is reduced by the rice with the RS1 genetically modified; a molecule mechanism for forming waterlogging tolerance of the rice is revealed, so that a new gene resource is provided for genetic improvement on waterlogging tolerance of the rice and other plants.

Description

technical field [0001] The invention relates to a rice flooding stress response RS1 gene, which belongs to the technical field of plant genetic engineering, in particular to a rice flooding stress response RS1 gene and application thereof. Background technique [0002] Stress response is when the plant body resists the stress of the adverse external environment, the plant cells sense the change of the external environment and transmit the signal to the cell, thereby inducing the cells to express various response genes to jointly resist the damage of the adverse environment to the plant body. process. [0003] Rice is one of the most important food crops in the world, and about 50% of the world's population depends on it as a staple food. At present, the continuous deterioration of the environment has caused a serious shortage and unbalanced distribution of global water resources, resulting in frequent occurrence of flood disasters in some areas. Flood disasters have become...

Problems solved by technology

At the same time, under flooding conditions, the photosynthesis of rice is also severely inhibited, which affects the normal growth of rice, resulting in reduced yields, or even no harvest.
