玉米新月弯孢叶斑病研究进展

 玉米弯孢叶斑病是一种世界性玉米病害,也是中国玉米产区的主要病害之一。20多年来,国内外在该病害发生规律、致病性分化与诱导抗性机理、生物防治技术等方面开展了深入研究。本文主要就该病害优势致病菌新月弯孢菌 Curvularia lunata (Wakker)Boedijn]的生物学特性、致病因子与生理分化机理、毒素结构鉴定、毒素合成与调控、诱导抗病性分子机理等方面的研究进展进行综述,以期对玉米弯孢叶斑病防控技术的创新提供参考。

Research progress on maize Curvularia leaf spot caused by Curvularia lunata

Curvularia leaf spot of maize is an important maize disease worldwide and one of the main diseases in maize producing areas in China. Over the past 20 years, the occurrence regularity, mechanism of pathogenicity differentiation and inducing resistance as well as biocontrol technology of the disease have been studied deeply in the world. In this paper, the biological characteristics, pathogenic factors, physiological differentiation mechanism, toxin synthesis and regulation of Curvularia lunata (Wakker)Boedijn and molecular mechanism of inducing resistance against the pathogen were extensively reviewed in order to provide reference for the innovation of control technique against curvularia leaf spot in maize.
