FIG 2.

Growth curves of Synechocystis sp. PCC 6803 wild-type (wt) and kpsM mutant strains (A) and the respective phenotypes showing the clumping of the mutant cells at lower cell densities (B). Cells were grown in BG11 medium at 30°C under a 12-h light (50 μE m⁻² s⁻¹)/12-h dark regimen, with orbital shaking at 150 rpm. Growth experiments were performed in triplicate, and statistical analysis is presented for the last time point (n.s., not significant[P value of >0.05]). Chl a, chlorophyll a.
