International Research Fellowship Program: Phylogenetic Analysis of the Phaeophyceae (Brown Algae) Based on rbcL and LSU Sequences

国际研究员奖励计划使美国科学家和工程师能够在国外进行三到二十四个月的研究。该计划的奖项提供了联合研究的机会，并利用国外独特或互补的设施、专业知识和实验条件。该奖项将为Naomi E.Phillips博士与加拿大弗雷德里克顿新不伦瑞克大学的Gary W.Saunders博士合作提供24个月的支持。该项目将使用rbcL和LSU序列信息来阐明褐藻(褐藻)之间的序贯和一些亲缘关系。褐藻是沿海海洋环境中最具优势和生物多样性的初级生产者群体之一。它们表现出广泛的形态，从简单的微观和宏观的细丝到巨大而复杂的实质叶状体。从经济上讲，褐藻是天然产品和生物医药用品的主要来源。尽管它们很重要，但研究才刚刚开始客观地审视进化关系，就反映系统发育关系的自然分类系统而言，还缺乏共识。我们开展全面的研究以了解这些资源，这对我们保护这些资源至关重要。这项研究的结果不仅将有助于我们对这一生物群的了解，而且将有助于未来在其他领域的研究，如生态学。加里·桑德斯是褐藻分类学方面的知名研究员，在传统和分子技术方面都有专长。

The program's awards provide opportunities for joint research, and the use of unique or complementary facilities, expertise and experimental conditions abroad.This award will provide twenty-four months of support to Dr. Naomi E. Phillips to work with Dr. Gary W. Saunders at the University of New Brunswick in Fredericton, Canada.This project will use the rbcL and LSU sequence information to elucidate the ordinal and some familial relationships among the Phaeophyceae (brown algae). Brown algae are one of the most dominant and biologically diverse groups of primary producers in coastal marine environments. They exhibit a wide range of morphological forms, from simple microscopic and macroscopic filaments to large and complex parenchymatous thalli. Economically, brown algae are major sources of natural products and biomedical supplies. Despite their importance, research is just beginning to examine objectively evolutionary relationships and a consensus in terms of a natural classification system that reflects phylogenetic relationships is missing. It is critical to our conservation of these resources that we initiate comprehensive studies to understand them. The results of this research will contribute no only to our understanding of this group of organisms, but will facilitate future research in other areas, such as ecology.Dr. Gary Saunders is an established researcher in brown algal systematics with expertise in both traditional and molecular techniques.
