Abiotic stresses such as drought, salt, low temperature and high temperature seriously affect the growth, development and yield of rice. Increasing rice yield under abiotic stress is of great practical significance for ensuring national food security. Using genetic engineering technology to improve rice yield under abiotic stress is an effective way superior to conventional breeding methods. At present, regulatory genes and functional genes have been confirmed to enhance rice yield under abiotic stresses. This paper systematically reviewed the research progress of these genes in improving rice yield under drought, salt, low temperature, high temperature and other single and combined stresses, and analyzed the existing problems, so as to provide reference for rice variety breeding for stress tolerance and high yield.
Key words: rice; abiotic stress; genetic engineering; regulatory gene; function genes; yield
