Medium Term Visit to Japan: Chitin Perception in Plants

9800099 Stacey该奖项提供资金支持田纳西大学微生物学系加里·斯泰西博士与日本筑波国立农业生物资源研究所生物技术系涩谷博士合作进行为期4个月的研究访问。 这两个合作者将从事比较研究的植物接收几丁质寡糖产生的感染细菌或真菌。 几丁质低聚糖（dp=7）能诱导水稻的防御反应，而脂几丁质低聚糖（dp=5）则能诱导根瘤菌侵染豆科植物时产生一种新的植物器官-根瘤。 前一种情况是致病的，后一种情况对植物有益。 合作者提出，关于植物几丁质的接收，这两个系统有许多共同的特点。 为了理解植物对信号的感知和传递，研究人员将研究感知微生物产生的信号的受体分子的详细特性。该项目是以豆类-甲壳素识别为研究重点的PI和以大米-甲壳素识别为研究重点的涩谷博士的跨学科合作。 此次访问获得了该奖项的支持，这将有助于进一步比较水稻和大豆几丁质结合蛋白。 该项目将是互惠互利的，因为研究人员计划双向交流思想，技能和技术。 ***

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. ***
