In this study, we describe the effect of red and blue light on the timing of commitment to cell division in Chlarnydomonas reinhardtii. The time point and cell size after which cells can complete their cell cycle with one division round were determined for cultures that were exposed to various red and blue light periods. We show that the commitment point of cells grown in blue light is shifted to a later time point and a larger cell size, when compared with cells grown in red light. This shift was reduced when cultures were exposed to shorter blue light periods. Furthermore, this shift occurred only when exposure to blue light started before the cells attained a particular size. We conclude that the critical cell size for cell division, which is the cell size at which commitment to cell division is attained, is dependent on spectral composition.
