Abstract
Differentiation of Chlamydomonas reinhardtii vegetative cells to gametes requires two environmental signals: nitrogen starvation and light. Vegetative cells incubated without nitrogen differentiate into pregametes. Pregametes can be converted into sexually mature gametes by irradiation with light. The action spectrum for the light-dependent step in gamete formation showed two maxima at 370 and 450 nanometers. This is similar to the spectrum of other blue light/ultraviolet light-A-absorbing photoreceptors.
摘要
衣藻营养细胞向配子分化需要两个环境信号
氮饥饿和光照。在无氮条件下培养的营养细胞分化为前配子。前配子可以通过光照转化为有性成熟的配子。配子形成中依赖光的步骤的作用光谱在 370 和 450 纳米处有两个最大值。这类似于其他蓝光/紫外光 A 吸收光受体的光谱。
