The marine dinoflagellate, Glenodinium sp., was cultured at a series of light levels and growth, pigmentation, and photosynthetic rates were compared. Under decreasing light conditions, growth rates decreased, cellular chlorophyll a and peridinin content per cell increased, and maximum cellular photosynthetic rates remained unchanged. Pigmentation changes were related to alterations in cellular concentrations of a peridinin-chlorophyll a-protein and an unidentified chlorophyll a component of the chloroplast membrane. Maintenance of photosynthetic rates with decreased irradiance is interpreted as an increase in the number of pigment molecules in the light-harvesting antenna associated with the reaction centers of the photosynthetic apparatus, thus increasing the potential for photon capture for photosynthesis.
海洋甲藻，Glenodinium sp.，在一系列光照水平下进行培养，并对其生长、色素沉着和光合速率进行了比较。在光照减弱的情况下，生长速度下降，细胞内叶绿素 a 和每细胞的 peridinin 含量增加，最大细胞光合速率保持不变。色素变化与细胞内 peridinin-chlorophyll a-蛋白和叶绿体膜中一种未鉴定的叶绿素 a 成分的浓度变化有关。在光照减弱的情况下维持光合速率被解释为与光合器官的反应中心相关的光捕获天线中色素分子数量的增加，从而增加了光合作用的光子捕获潜力。
