The role of Ca2+ for the signaling of rhodotorucine A, a mating pheromone of Rhodosporidium toruloides, was investigated. The efficiency with which the target cells responded to the mating pheromone was dependent on the Ca2+ concentration in the medium. The pheromone induced a very rapid and transient increase of Ca2+ uptake in the recipient cell. We concluded that the transient increase in the intracellular Ca2+ concentration could play an essential role in the control of differentiation by the pheromone.
研究了Ca2+在罗伦隐球酵母交配信息素红球藻氨酸信号传导中的作用。靶细胞对交配信息素的反应效率取决于培养基中的Ca2+浓度。该信息素可诱导受体细胞中Ca2+摄取迅速且短暂地增加。我们得出结论,细胞内Ca2+浓度的短暂增加可能在信息素对分化的控制中起重要作用。
