乙烯是一种调节植物多方面生长和发育的植物激素。一般认为,在乙烯发挥其生理作用之前,首先结合到一受体中以形成复合体,这个复合体依次激发最初的生物化学反应,最后转变为多样性的乙烯反应。毫无疑问,基因表现的调节作用也包括在最后过程中,但有关这方面我们知道得很少。 Ethylene is a plant hormone that regulates many aspects of plant growth and development. It is generally believed that before ethylene exerts its physiological effect, it first binds to a receptor to form a complex that, in turn, stimulates the initial biochemical reaction and, eventually, to a diverse ethylene reaction. There is no doubt that the regulatory role of gene expression is also included in the final process, but we know very little about this.
