Protochlorophyll accumulation in wild-type and transgenic BVR seedling extracts. Transgenic M-pBVR lines and M-cBVR lines were compared with cv Maryland Mammoth WT seedlings grown at 25°C on phytagel medium containing 1% (w/v) Suc for 15 d in darkness. Bars indicate the relative protochlorophyll fluorescence values calculated by normalizing to the fluorescence value of WT seedling extracts (see “Materials and Methods” for details). Values represent the mean (±sd) of three independent measurements.
