Identification and fine mapping of a new gene BPH31 conferring resistance to brown planthopper biotype 4 of India to improve rice Oryza sativa L

摘要

BackgroundRice (Oryza sativa L.) is the staple food for more than 3.5 billion people, mainly in Asia. Brown planthopper (BPH) is one of the most destructive insect pests of rice that limits rice production. Host-plant resistance is one of the most efficient ways to overcome BPH damage to the rice crop.
