Outline of Final Research Achievements

Certain cyanobacteria species modulate their photosynthetic antenna proteins, phycocyanin and phycoerythrin, which is a phenomenon called complementary chromatic acclimation (CCA). Recent studies of typical CCA-capable cyanobacteria species suggest the diversity of green and red light-regulated gene set during CCA. In this project, I performed (1) establishment of efficient analysis pipeline of cyanobacterial genomes, (2) de novo genome sequencing of CCA-capable cyanobacteria species, and (3) RNA-Seq and spectral analysis of several cyanobacteria performing unique CCA. These results will facilitate the understanding of the molecular basis of CCA and also many other researches of the cyanobacterial genomes.
