Temperature Adaptation of Brown Algal Photosynthesis

这项研究涉及北美高纬度水域常见的某些类型的海藻(特别是海带属海带)在低温(0-20摄氏度)下保持快速光合作用的机制。人们对这种低温光合作用适应现象知之甚少。这项拟议工作的结果将对我们理解海藻的光合作用产生重大影响，海藻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的光合作用机制所做的适应可能会有广泛的应用，从这些植物的水产养殖到更好地理解如何使陆地上的作物更耐寒。

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.
