U.S.-Australia Cooperative Research: Genetic and Molecular Characterization of Rhizoctonia Solani AG-3 and AG-8

小行星9417839 该奖项将部分支持唐纳德·E·博士的旅行和生活费用。阿拉斯加大学费尔班克斯植物、动物和土壤科学系的卡林，当时他正在澳大利亚休假。 Carling博士将与位于西澳大利亚珀斯的默多克大学生物与环境科学学院的Philip奥布莱恩博士合作。研究 将集中在遗传和分子特征的立枯丝核菌，寄生植物真菌。 R.茄病是一种重要的农作物病原菌，但其遗传学、致病特性和分子生物学研究尚不清楚。 立枯丝核菌根据相关分离物的菌丝相互连接的能力分为许多亚种组，称为吻合组（AG）。 研究将在R. solani AG-3，其对马铃薯和烟草植物有毒力，以及对AG-8的异源和同核分离株有毒力或无毒力，对马铃薯和小麦植物的根有毒力或无毒力。 奥布莱恩博士和他的同事一直在研究R. Solani，并完善了用研究交配和不亲和系统的原生质体方法产生同核分离物的技术。 Carling博士及其团队一直积极参与新吻合术分组的表征。 这项研究汇集了两个研究小组的互补技能。 这项研究活动最终可能导致增加作物产量，同时使用更少的化学制剂来控制疾病。 该奖项得到了 美国--澳大利亚合作科学计划。 ***

9417839 Carling This award will partially support the travel and living expenses for Dr. Donald E. Carling, Department of Plant, Animal and Soil Science at the University of Alaska Fairbanks, while he is on sabbatical leave in Australia. Dr. Carling will be working in collaboration with Dr. Philip O'Brien of the School of Biological and Environmental Science at Murdoch University located in Perth, Western Australia. The research will focus on the genetic and molecular characterization of Rhizoctonia solani, a parasitic plant fungi. R. solani is an important pathogen among crop plants, yet little is known about its genetics, pathogenicity characteristics, and molecular biology. R.solani is divided into a number of subspecific groups called anastomosis groups (AG) based upon the ability of hyphae of related isolates to interconnect. Research will be conducted on collections of R. solani AG-3 that are virulent on potato and tobacco plants and on heterokaryotic and homokaryotic isolates of AG-8 that are either virulent or avirulent on the roots of potato and wheat plants. Dr. O'Brien and his colleagues have been studying the molecular biology of R. solani and have perfected a technique of generating homokaryotic isolates with a protoplast procedure used in studying mating and incompatibility systems. Dr. Carling and his group have been active in the characterization of new anastomosis groupings. The study brings together the complementary skills of the two research groups. The research activity could ultimately lead to increasing crop yields while using fewer chemical agents to control disease. The award is supported under the U.S.-Australia Cooperative Science Program. ***
