摘 要 ：油菜菌核病是由核盘菌Sclerotinia sclerotiorum引起的重要病害。近年来,随着油菜免耕直播栽培技术的推广,油菜菌核病的发生呈逐年上升趋势。目前,防治油菜菌核病主要依赖化学防治,但过量施药给生态环境和食品安全带来极大压力。盾壳霉Coniothyrium minitans是核盘菌上的一种重要寄生菌,因其对多种作物菌核病具有防治作用,在一些国家和地区已被开发成商品制剂。但在田间利用盾壳霉防治油菜菌核病的研究鲜见报道。Cheng等和姜道宏等研究表明,分离自湖北省竹山县蔬菜种植园土壤的盾壳霉ZS-1菌株可产生大量分生孢子,对核盘菌菌核有极强寄生作用,且对油菜菌核病具有较好的田间防治效果。作者等于2008—2010年在湖北省黄冈市和武穴市的免耕直播田测定了盾壳霉ZS-1菌株对油菜菌核病的防治效果,并进行了大田示范试验。

Abstract:Sugarcane yellow leaf virus (SCYLV) is associated with the sugarcane yellow leaf disease (SCYLD), which has become a serious threat to the sugarcane industry worldwide since the last two decades. The virus infects the phloem tissue, and it is transmitted by the aphid Melanaphis sacchari. SCYLV is thought to have arisen from several recombination events among members of the genera Luterovirus, Polerovius and Enamovus basis on the heterogeneous affinities of its genomic sequence and then is assigned to the genus Polerovirus of the family Luteoviridae by the International Committee on the Taxonomy of Viruses (ICTV). Research advances in SCYLV and its associated disease are summarized in this review including the aspects of the viral biology characteristics, occurrence and effect on sugarcane, methods of identification and detection, molecular evolution and genetic diversity, viral genomic construct and putative genes function as well as transgenic sugarcane of disease resistance. Conventional disease-resistance breeding and control measures were also discussed.
