Method Primary source Neale and Melis abstract: "Chlamydomonas reinhardtii was grown at photon flux densities (PFDs) ranging from 47 to 400 μE/m^2/s." Primary source Bonente et al., abstract: "[Investigators] report on the changes the photosynthetic apparatus of Chlamydomonas reinhardtii undergoes upon acclimation to different light intensity."
Comments P.1494 right column bottom paragraph: "It has been observed that long-term high-light exposure of C. reinhardtii cells leads to a 50% decrease of Chl content (primary sources) and to changes in Chl-to-Car [carotenoid] ratio (Niyogi et al., 1997a, Baroli et al., 2003, primary source Bonente et al., 2012), suggesting reduction of the antenna size (primary source Neale and Melis, 1986), although, in a more recent report (primary source Bonente et al., 2012), it was concluded that the antenna size is not modulated by light in this alga."
