Temperature Adaptation of Brown Algal Photosynthesis

这项研究关注的是使北美高纬度水域常见的某些类型的海藻（特别是属于海带属的海带）在低温（0-20摄氏度）下保持快速光合作用的机制。这种适应低温光合作用的现象尚不清楚。拟议工作的结果将对我们对海洋藻类光合作用的理解产生重大影响，海洋藻类占地球上植物生长的三分之一以上。此外，更好地了解这些海带在极端条件下对其光合作用机制的适应性，可能会应用于从这些植物的水产养殖到提高对陆地作物植物如何更耐寒的理解。

This study concerns the mechanisms that enable certain types of seaweed common to high latitude North American waters (specifically kelp belonging to the Laminaria genus) to maintain rapid rates of photosynthesis at low temperatures (0-20 degrees centigrade). This phenomenon of low temperature photosynthetic adaptation is poorly understood. The results of the proposed work will have a major impact on our understanding of photosynthesis in marine algae that account for over a third of the plant growth on the planet. Also, a better understanding of the adaptations these kelp have made in their photosynthetic machinery at extreme conditions may have applications ranging from the aquaculture of these plants to the improved understanding of how crop plants on land can be made more resistent to cold.
