Photoinhibition of GL observed in the field-grown conditions. Top panel, a typical diurnal change in PPFD (▪) on the leaves and atmospheric temperature (□) in the field. Bottom panel, a diurnal change in maximum PSII efficiency of intact attached leaves in the field. (•, blue), WT; (Δ red), GL. Fv/Fm value was measured as PSII efficiency with a portable chlorophyll a fluorometer (PAM-2000). Each data point is the mean of 10 separate measurements ± SD.
