U.S.-China Cooperative Research: Nitrogen Metabolism in Laminaria Japonica

这项建议是为了支持对褐藻海带氮代谢的季节性研究。这些研究将侧重于缺氮、硝酸盐利用和海带生长之间的关系，目的是为海藻自然种群建立生产性受精方法，同时评估与限制氮素生长的时间有关的问题。这项工作将由纽约州立大学石溪分校的Boudewijn Brinkuis博士和中国科学院青岛海洋研究所的吴朝云博士根据美中基础科学合作议定书的条款进行。拟议的研究将利用中国为应对海带(海带)的商业需求而积累的大量经验知识。这种海藻是主要的食用和化学提取物海藻之一，自20世纪50年代初S以来在中国大量生产。虽然对海带物种进行了其他研究，但到目前为止还没有研究着眼于商业海带--海带。这项研究虽然具有潜在的实用价值，但也将试图回答在早期关于海带氮代谢的研究中尚未解决的问题。实地研究将在中国进行，实验室分析将在中科院青岛实验室和纽约州立大学石溪分校进行。

This proposal is for support of a seasonal study of the nitrogen metabolism of the brown alga Laminaria japonica. The studies will focus on the relationships between nitrogen deficiency, nitrate utilization and kelp growth with the goal of establishing a productive fertilization approach for natural populations of the alga while assessing questions relating to the timing of nitrogen-limited growth. The work will be conducted by Dr. Boudewijn Brinkuis, SUNY at Stony Brook, and Dr. Wu Chaoyun, Chinese Academy of Science's Institute of Oceanology, Qingdao, China, under the terms of the US-PRC Protocol for Cooperation in Basic Sciences. The proposed research will draw on a vast store of empirical knowledge which China has accumulated in response to the commercial demand for kelp (laminaria). This seaweed is one of the major seaweeds used for food and chemical extracts and has been mass produced in China since the early 1950's. While other studies have been conducted on kelp species, no studies to date have looked at the commercial kelp, Laminaria japonica. This study, while of potential practical benefit, will also attempt to answer questions unresolved in earlier research on nitrogen metabolism in kelp. Field studies will be conducted in China and laboratory analyses will take place both in the CAS laboratories in Qingdao and at SUNY Stony Brook.
