Chlorophyll fluorescence analysis of transgenic C. vulgaris cells. Potential maximal quantum efficiency of PSII (F v/F m) (a), efficiency of open PSII centers in light (F v′/F m′) (b), non-photochemical quenching coefficient (NPQ) (c), photochemical quenching coefficient (qP) (d), and quantum yield of PSII (Φ PSII) (e) were, respectively, determined in transformants and wild-type (WT) cells. Prior to measurement of chlorophyll fluorescence, algal cells were adjusted to a concentration of 10 µg of chlorophyll a per mL and incubated under normal culture conditions for several hours. The data are expressed as mean ± SD from three independent experiments. Asterisks show significant difference from WT cells (t test, *P < 0.05)
