项目摘要

This project utilizes the power of phylogenetic systematics to identify and classify specialized species of fungi associated with wild rubber trees (Hevea). A goal of the project is to document fungal species that can be used in biological control of devastating Hevea diseases, including the South American Leaf Blight (SALB). The project will: characterize fungal species associated with wild Hevea species by collecting and identifying the fungi using modern phylogenetic tools; elucidate coevolutionary patterns between fungi and their hosts, and host preferences, by analyzing and comparing phylogenies of selected fungi and their corresponding plant hosts; and identify biocontrol agents against Hevea diseases by evaluating selected fungi in biocontrol assays.The largest and most productive commercial rubber plantations are in Asia and Africa. This is due to the difficulty of establishing plantations in regions where SALB exists. SALB is not yet present in Africa or Asia, and its potential spread to these continents represents significant biological and economic concerns. Even though potential impacts of SALB are large, few control methods have been published. Fungal biocontrol against Hevea diseases could be part of this solution.
本计画利用系统发生学的力量,来鉴定与野生橡胶树(橡胶树)相关的真菌的特化种类并加以分类。该项目的一个目标是记录可用于生物防治毁灭性橡胶树疾病的真菌物种,包括南美叶枯病(SALB)。该项目将:利用现代系统发育学工具,通过收集和鉴定与野生橡胶树种相关的真菌,来描述其特征;通过分析和比较所选真菌及其相应植物宿主的系统发育,来阐明真菌与其宿主之间的共同进化模式和宿主偏好;并通过在生物防治试验中评估所选真菌来鉴定针对橡胶树病害的生物防治剂。种植园在亚洲和非洲。这是由于在存在SALB的地区建立种植园的困难。SALB尚未出现在非洲或亚洲,其向这些大陆传播的可能性代表了重大的生物和经济问题。尽管SALB的潜在影响很大,但已公布的控制方法很少。针对橡胶树病害的真菌生物防治可能是这一解决方案的一部分。
