Progress in exploitation and utilization of brown planthopper resistance gene in rice
SCIENTIA SINICA Vitae(2022)
Rice is the most important food crop globally and a model species for basic biological research. Brown planthopper (BPH) is one of the major insect pests of rice. In the past decades, scientists have explored the BPH resistance gene from rice germplasm and revealed the molecular mechanism underlying the host plant resistance of rice to BPH. Research results have promoted the development of BPH-resistant rice varieties and their release in rice production. This review briefly introduces the research progress on brown planthopper resistance gene discovery, mechanism analysis, germplasm innovation, and utilization in rice breeding programs to help readers understand the mystery of plant resistance against insects and the practical significance of insect resistance research in plants.
