Fig. 2From: Chlorophyll fluorescence as a light signal enhances iron uptake by the marine diatom Phaeodactylum tricornutum under high-cell density conditionsRelative intracellular Fe content of ISIP2a-S1 and ISIP2a-S2 under different cell densities. L for low-cell density, M for middle cell density, and H for high-cell density. The cell was incubated for 24 h under white light (a) or dark conditions (b). Intracellular Fe content was normalized by WL-L group of WT. Data was shown as mean values ± SD for three independent experimentsBack to article page
