Molecular analysis of photosynthetically-linked, active CO2 uptake and CO2 signal transduction by cyanobacteria (blue-green algae).

蓝藻(蓝藻)与光合作用相关的活性二氧化碳吸收和二氧化碳信号转导的分子分析。蓝藻(蓝藻)已经进化出一种非常有效的方法来捕获和浓缩二氧化碳，用于光合作用固定成糖，糖是细胞生长的基本构件。这一过程依赖于几个独特的、活跃的二氧化碳和HCO3-吸收系统的运行，它们的基因表达受到二氧化碳供应的调节。这项提议将利用我们在描述这一过程的功能遗传学方面的进展，旨在阐明主动吸收二氧化碳的机制和细胞感知环境二氧化碳浓度的方式。所获得的信息可能有助于设计改良作物。

Molecular analysis of photosynthetically-linked, active CO2 uptake and CO2 signal transduction by cyanobacteria (blue-green algae). Cyanobacteria (blue-green algae) have evolved a very efficient means of capturing and concentrating CO2 for photosynthetic fixation into sugars, the basic building blocks for cell growth. This process is dependent on the operation of several unique, active uptake systems for CO2 and HCO3-, with their genetic expression regulated by CO2 supply. This proposal will capitalize on our progress in describing the functional genetics of this process and aims to elucidate the mechanism of active CO2 uptake and the way that cells sense the ambient CO2 concentration. The information gained is likely to be useful for designing improved crops.
