The yeast pheromone response pathway works in a graded fashion, such that more pheromone leads to more response, but a recent study has shown that small modifications convert it into a bistable switch, with implications for the evolution and engineering of reaction networks.
酵母信息素反应途径以分级方式起作用，即更多的信息素会导致更多的反应，但最近的一项研究表明，微小的修饰可将其转化为双稳态开关，这对反应网络的进化和工程设计具有重要意义。
