Rice moderate leaf-rolling mutator RL14 and application thereof

Abstract

The invention discloses a nucleotide sequence and a coding protein sequence of a rice moderate leaf-rolling mutator RL14, thus providing a powerful tool for rice transgenic research and promoting the breeding research on high-yield and high-quality rice.

Description

technical field [0001] The invention belongs to the technical field of genetic engineering, relates to a rice mutant gene, and also relates to the application of the mutant gene. Background technique [0002] Rice (Orvza sativa L.) is one of the most important food crops in the world, and nearly half of the world's population uses rice as a staple food. With the continuous increase of the world's population and the continuous reduction of arable land, food security has become a worldwide problem. Rice is a C3 plant with strong photorespiration and low effective photosynthetic rate, especially during the grain filling stage of rice in high temperature and drought areas. Due to the high temperature, its photorespiration will waste a lot of photosynthetic products, which will not only affect the yield, but also seriously affect Rice quality. Therefore, increasing the effective photosynthetic rate is an effective way to increase rice yield and improve rice quality. To achieve...

Problems solved by technology

However, the rice curling materials that have been found so far have great differences in the degree of curling of the leaves, and most of them are of low value in production.
