Medium Term Visit to Japan: Chitin Perception in Plants

9800099本奖项提供资金支持田纳西大学微生物学系Gary Stacey博士与日本筑波国立农业生物资源研究所生物技术系Naoto Shibuya博士合作进行为期4个月的研究访问。这两位合作者将从事植物对感染细菌或真菌产生的甲壳素低聚糖的接受情况的比较研究。病原菌释放的甲壳素低聚糖(DP=7)诱导水稻的植物防御反应，而脂-甲壳素低聚糖(DP=5)在根瘤菌侵染过程中诱导豆类植物新器官--根瘤的发育。前一种情况是致病的，后一种情况对植物有利。合作者提出，关于植物甲壳素的接收，这两个系统有许多共同的特征。为了了解植物对信号的感知和转导，研究人员将研究感知微生物产生信号的受体分子的详细性质。该项目涉及PI和涉谷博士之间的跨学科合作，PI的研究重点是豆类-甲壳素识别，涉谷博士的研究重点是水稻-甲壳素识别。由该奖项支持的访问将允许对大米和大豆几丁质结合蛋白进行进一步比较。该项目将互惠互利，因为研究人员计划进行思想、技能和技术的双向交流。***

9800099StaceyThis award provides funds to support a 4-month research visit by Dr. Gary Stacey, Department of Microbiology, University of Tennessee, for collaboration with Dr. Naoto Shibuya, Department of Biotechnology, National Institute of Agrobiological Resources, Tsukuba, Japan. These two collaborators will be engaged in comparative studies of plant reception of chitin oligosaccharides produced by infecting bacteria or fungi. Chitin oligosaccharides (dp=7) released from fungal pathogens induce plant defense reactions in rice, while lipo-chitin oligosaccharides (dp=5) induce the development of a new plant organ, the nodule, in legumes during infection by rhizobia. The former situation is pathogenic and the latter situation beneficial to the plant. The collaborators propose that, with regard to plant chitin reception, these two systems share many common features. In order to understand the perception and transduction of signals by plants, the researchers will study the detailed properties of the receptor molecules which perceive the microbe produced signal.This project involves interdisciplinary collaboration between the PI, whose research has focused on legume-chitin recognition, and Dr. Shibuya, whose research has focused on rice-chitin recognition. The visit supported by this award will allow a further comparison of the rice and soybean chitin binding proteins. The project will be mutually beneficial because of the two-way exchanges of ideas, skills, and techniques planned by the researchers. ***
