虫媒传播作物病害机制研究进展
Mechanistic research advances in insect-borne crop diseases
摘要
Abstract
[Background]Insect-borne diseases pose a serious threat to food and cash crop production,and the persistent damage they cause has become a major bottleneck restricting China's agricultural and forestry biosafety.Among them,rice viral diseases,Huanglongbing(HLB),and rice orange leaf disease(ROLD)frequently break out in China,resulting in significant economic los-ses,with insects serving as the key vectors.[Progress]Studies on major vector-borne crop diseases,including rice viral diseases,HLB and phytoplasma diseases,have made substantial progress in elucidating pathogen infection and circulation within insect vec-tors,horizontal and vertical pathogen transmission,pathogen traversal of tissue barriers,and pathogen-vector immune interactions.Focusing on the core scientific question of how insect vectors transmit pathogens and cause disease in crops,this review systematical-ly summarizes the molecular mechanisms underlying the transmission of vector-borne crop diseases,immune regulation in insect vec-tors,pathogen dissemination across tissue barriers,and ecological adaptation strategies from the perspective of pathogen-vector-host interactions.It also discusses the potential applications of these findings in the environmentally sustainable management of vector-borne crop diseases.[Prospect]Future studies should further elucidate of the mechanisms pathogen-vector-host interactions and pathogen transmission across tissue barriers,identify key targets for blocking pathogen transmission,and promote innovations in transmission-blocking and ecological control technologies,thereby providing a theoretical basis and technical support for the sustain-able management of vector-borne crop diseases.关键词
