Fig. 5From: Potassium channel KCN11 is required for maintaining cellular osmolarity during nitrogen starvation to control proper cell physiology and TAG accumulation in Chlamydomonas reinhardtiiRemoving potassium from culture media partially rescues formation of lipid droplets. WT or kcn11 cells were grown in N-depleted medium for 2 days with or without potassium followed by Nile Red staining (a), by measurement of cellular number (b) and size (c) of the lipid droplets. Bar = 5 µm. Data shown are mean ± sem (n = 50). N.S., no significant. *P < 0.05, ***P < 0.0001 (t test)Back to article page
