水稻抗褐飞虱基因的发掘与育种利用

Progress in exploitation and utilization of brown planthopper resistance gene in rice

水稻(Oryza sativa)是世界上最重要的粮食作物,也是生物学基础研究的模式植物.褐飞虱(Nilaparvata lugens Stål,BPH)是全球水稻生产中的主要害虫之一.半个多世纪以来,水稻科学家坚持从水稻种质资源库中发掘抗褐飞虱基因,深入研究抗褐飞虱机理,促进了水稻抗褐飞虱品种的培育与应用.本文以几个典型抗褐飞虱基因为重点,对水稻抗褐飞虱基因发掘、机理解析、种质创新和育种利用的研究进展作一简要介绍,以帮助读者了解植物抗虫性的奥秘以及抗虫性研究的重要意义.

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.
