| Research Abstract |
In the five years, we performed post-genome analyses of unicellular cyanobacterium Synechocystis sp. PCC 6803 and Anabaena sp. PCC 7120, construction of resources and databases, genome determination of thermophilic cyanobacterium Thermosynechococcus elongatus BP-1 and ancient cyanobacterium Gloeobacter violaceus PCC 7421. As for Synechocystis, we performed large scale functional analysis and identified many genes mainly in photosynthesis and related metabolism, stress responses, environmental responses, signal recognition and transduction and cell motility. We also analyzed global gene expression profiles under various gene inactivation and environmental conditions. As for Anabaena sp. PCC 7120, we identified many genes involved in multistep development of nitrogen-fixation, responses to desiccation and salt stresses and signal transduction employing cAMP as a second messenger. As for resources, we established gene disruptant bank of Synechocystis microarray databases, gene reannotation database. We also developed genome-segment microarray and oligonucleotide-based microarray for Anabaena. With these studies, we identified a number of hypothetical genes as critical factors for physiology of phototrophic microorganisms.
