项目摘要

0096793Myrold Description: This award supports a US-India cooperative research project on Molecular Diversity of Actinorhizal Symbionts Found in the Sikkim Region of the Eastern Himalayas. US PI David Myrold, Oregon State University and Indian co-PI Arvind Misra, North Eastern Hill University, Shillong will study the molecular diversity of Frankia that nodulate several actinorhizal plants in the eastern Himalayas. This research extends previous studies on the molecular diversity of Frankia, an important N2 -fixing bacteria genus, to include strains from the montane region of India. The objectives are to: 1) assess the molecular diversity of Frankia as a function of host plant and geographical location, and 2) use sequence information to add to the current phylogenetic tree of Frankia. Scope: This work builds on the joint expertise of the PIs in using molecular methods to study Frankia. Research results will complement studies done in North America and Oceania, which have yielded differing results regarding the relative importance of host plant species or environmental factors as determinants of Frankia diversity. Practically, this research may prove useful in attempts to use actinorhizal plants in revegetation and restoration efforts, as they are important early colonizers of disturbed sites. This award is jointly supported by the Division of International Programs and the Division of Environmental Biology.

描述：该奖项支持美印合作研究项目，研究东喜马拉雅山锡金地区放线菌共生体的分子多样性。俄勒冈州立大学的美国PI David Myrold和西隆东北山大学的印度联合PI Arvind Misra将研究喜马拉雅山脉东部几种放射线根植物结结的Frankia的分子多样性。这项研究扩展了先前对Frankia（一种重要的N2固定细菌属）分子多样性的研究，将来自印度山区的菌株包括在内。目的是：1)评估Frankia的分子多样性作为寄主植物和地理位置的功能；2)利用序列信息增加Frankia现有的系统发育树。范围：这项工作建立在pi使用分子方法研究Frankia的联合专业知识的基础上。研究结果将补充在北美和大洋洲进行的研究，这些研究在寄主植物物种或环境因素作为法兰克植物多样性决定因素的相对重要性方面产生了不同的结果。实际上，这项研究可能会证明在植被恢复和恢复工作中使用放线根植物的尝试是有用的，因为它们是受干扰地点的重要早期殖民者。该奖项由国际项目部和环境生物学部联合支持。
