Fig. 2From: Potassium channel KCN11 is required for maintaining cellular osmolarity during nitrogen starvation to control proper cell physiology and TAG accumulation in Chlamydomonas reinhardtiiKCN11 deletion results in abnormal cell morphology and cell growth. a, b Flagella loss caused by KCN11 mutation under N-depleted condition. Shown are representative cell images after N starvation for 24 h (a) and flagellar loss kinetics during N starvation (b). Data shown are mean ± sem (n = 200). Bar = 5 μm. c Cell volume increase in kcn11 under N-depleted condition. Cells were measured after 24 h at the indicated media. Data shown are mean ± sem (n = 200). N.S., no significant. ***P < 0.0001 (t test). d Cell growth of kcn11 was inhibited following N starvation. Data shown are mean ± sem (n = 200). e, f Loss of chlorophyll is retarded in kcn11 following N starvation. Images of cell cultures grown in N-replete or N-depleted conditions for 24 h (e). Chlorophyll content during N starvation (f). Data shown are mean ± sem (n = 3)Back to article page
