摘要
全球的农作物每年因为病虫害导致的产量损失在11%-30%,大量的化学农药被用来控制病虫害的发生和蔓延,不仅污染环境,还严重影响人们的食品安全和身体健康.因此,利用抗病虫基因改良选育作物新品种是控制病虫害发生最经济有效的措施,也是未来我国农业绿色发展的必由之路.近几年,随着现代分子生物学的不断突破,带动了植物免疫与抗病虫研究取得突飞猛进的发展.本文重点围绕植物先天免疫基本框架和重要农作物与病原菌或害虫的互作研究体系,系统梳理了植物免疫受体的鉴定克隆以及信号通路建立、植物抗病与生长发育平衡调控以及农作物抗病虫基因克隆及互作机制研究方面的重要进展,归纳了植物免疫及抗病虫基础理论对作物抗病虫育种的贡献,提出了我国农作物抗病虫研究领域存在的瓶颈问题及解决办法,对未来我国农作物抗病虫研究提出新的发展方向,为适应我国未来农业发展的新趋势,有效开展农作物病虫害的控制奠定坚实的理论基础和分子技术支撑.
The yield loss of crops per year in the world is 11%–30% due to crop diseases and pests. A large number of chemical pesticides are used to control the spread of infectious crop diseases and pests every year, which not only pollutes the environment, but also seriously threatens food safety and human health. Therefore, the most economical and effective measure to control crop diseases and insects is to develop the resistant varieties by the utilization of resistance genes(R), and it is also the preferable way for sustainable development of future agriculture in China. In recent years, much progress has been made in molecular mechanism of plant innate immunity and isolation of many immune receptors including PRRs and NLRs from crops, molecular mechanism of interactions between insects and crops, and identification and cloning of crop insect resistance genes. We review the recent important breakthroughs in plant immunity and broad-spectrum resistance genes isolated in crops, and trade-off between resistance and other agronomic traits. We point out the bottlenecks in crop breeding for disease and insect resistance, and also propose new insights for plant disease and insect resistance research in China in the future.
