在单细胞红藻中，P. cruentum和P. aerugineum的藻胆蛋白含量受施加能量影响率的调节。低能量影响率（200.mu）培养的细胞。wcm -2)比在高能量影响率（3200.mu）下生长的细胞拥有多达3倍的藻胆蛋白。W cm-2)。这些值是通过直接测量藻胆蛋白的载脂蛋白得到的。细胞从低能量影响率到高能量影响率的转移，反之亦然，导致藻胆蛋白含量适应新的光照条件。这个过程在细胞转移后立即开始，需要几天时间。另一方面，核酮糖-1,5-二磷酸羧化酶（也是红藻质体的重要蛋白质）的数量在不同的影响率下没有显著变化。
In the unicellular red algae P. cruentum and P. aerugineum the phycobiliprotein content of the plastids is regulated by the applied energy fluence rate. Cells cultured at low energy fluence rates (200 .mu.W cm-2) possess up to 3 times more phycobiliproteins than cells grown at high energy fluence rates (3200 .mu.W cm-2). These values were obtained by direct measurement of the apoprotein of the phycobiliproteins. Transfer of cells from low to high energy fluence rates and vice versa results in an adaptation of the phycobiliprotein content to the new light conditions. This process starts immediately after the transfer of the cells and requires several days. On the other hand, the amount of the enzyme ribulose-1,5-bisphosphate carboxylase, which is also a prominent protein of the plastids of red algae, does not change significantly in response to differing fluence rates.
