Abstract

Cyanobacterial genomes encode several isoforms of the D1 (PsbA) subunit of Photosystem II (PSII). The distinct regulation of each isoform ensures adaptation under changing environmental conditions. Uncovering the missing elements of signal transduction pathways and psbA gene expression could open new avenues in engineering programs of cyanobacterial strains.

Keywords: D1 subunit; PsbA protein; histidine kinase; response regulator; sigma factor.
