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. ***

9417839 Carling该奖项将部分支持阿拉斯加费尔班克斯大学植物、动物和土壤科学系Donald E. Carling博士在澳大利亚休假期间的旅行和生活费用。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 O'Brien博士合作。本研究将重点研究植物寄生真菌solani Rhizoctonia的遗传和分子特征。茄蚜是一种重要的作物病原菌，目前对其遗传、致病性、分子生物学等方面的研究还很少。根据相关分离株菌丝相互连接的能力，茄茄弧菌被分为许多称为吻合群（AG）的亚特异性群体。将对对马铃薯和烟草植株有毒力的茄枯病菌AG-3和对马铃薯和小麦植株的根有毒力或无毒的异核和同核菌株AG-8进行研究。奥布莱恩博士和他的同事们一直在研究索拉尼真菌的分子生物学，并已经完善了一种用原生质体程序产生同核分离物的技术，这种原生质体程序曾用于研究交配和不相容系统。Carling博士和他的团队一直积极参与新的吻合组的表征。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在使用更少的化学制剂来控制疾病的同时提高作物产量。该奖项由美国-澳大利亚合作科学项目资助。＊＊＊
