Researchers use genome sequencing to inform various cellular processes in land plants and algae, including the details of photosynthesis. Despite the access to an increasing number of plant genomes (most of which have been generated by the DOE JGI), it remains difficult to correlate protein information with function, until now. For example, identifying the role proteins play in the evolution of chloroplasts and how the photosynthetic apparatus responds under different conditions.
This tool is called the GreenCut2. In the June 17, 2011 issue of The Journal of Biological Chemistry, researchers used GreenCut2 to derive an inventory of proteins specific to the plant lineage and to identify the function of 286 out of 597 proteins from 20 plant genomes.
