叶蝉传水稻条纹花叶病毒研究进展
Research advances in leafhopper-transmitted rice stripe mosaic virus
摘要
Abstract
Rice stripe mosaic virus(RSMV),transmitted by the leafhopper Recilia dorsalis,is a recently characterized as leafhopper-borne rice virus.First discovered in Luoding City,Guangdong Province,southern China in 2015,RSMV has since spread to rice-growing regions in neighboring provinces(autonomous regions or municipalities)in South China.Both the distribution area and severity of rice diseases caused by RSMV have been increasing annually,and this virus has become one of the key constraints to rice production in South China,posing a significant threat to regional rice security.In this article,we systematically reviewed the important research progress in RSMV over recent years,focusing on its occurrence status,epidemic patterns,biological characteristics and virus-vector-host plant interaction mechanisms,and identified five critical research priorities,aiming to provide a theoretical basis and practical reference for further in-depth research and scientific,efficient prevention and control of this disease.Current research has comprehensively elucidated the viral characteristics of RSMV and its persistent-propagative transmission by R.dorsalis.Significant breakthroughs have been achieved in deciphering the molecular mechanisms underlying these virus-vector-host interactions.Specifically,virus-encoded proteins have been shown to bidirectionally manipulate the physiological activities of both the insect vector(altering behavior or reducing cold tolerance)and rice host(e.g.,systemically suppressing hormones and RNA silencing-based disease resistance pathways),thereby enhancing the viral infection and transmission.To address the ongoing challenges in disease management,five pivotal research priorities have been identified and urgently require further investigation:(1)Clarifying the ecological mechanisms of viral overwintering to lay solid prediction and forecasting bases;(2)Accelerating the screening and breeding of resistant rice varieties to establish sustainable control systems;(3)Delineating the intricate mechanisms of virus-vector-host tripartite interaction to open novel control paths;(4)Developing specific viral inhibitors or transmission-blocking agents to enable precise and eco-friendly control strategies;and(5)Constructing viral infectious clones to facilitate gene function studies and innovative breeding applications.关键词
