Pigment content dynamics in WT (a, b) and ΔHik34 mutant (c, d) cells during heat stress and recovery. a, c—Absorption spectra normalized to zero at 750 nm. b, d—cellular chlorophyll a and carotenoid content. Dashed lines mark time of heat shock treatment. The results represent a typical data of 4 independent experiments for both WT and ΔHik34 mutant. Error bars in panels b and d indicate standard deviations from 3 technical repetitions.
