乙烯（C2H4）是化学上最简单的植物激素，也是最具代表性的植物生长调节剂之一。它参与各种应激反应和发育过程。拟南芥的遗传学研究已经确定了乙烯信号转导途径中的许多基因。对其中两个基因的分离表明，植物通过类似于原核和真核信号蛋白的蛋白质组合来感知这种气体。乙烯信号组分可能是保守的反应，如不同的细胞伸长，根表皮细胞命运的图案，和果实成熟。这些基因的遗传操作将为农业提供新的工具，以防止或修改各种植物的乙烯反应。
Ethylene (C2H4), the chemically simplest plant hormone, is among the best-characterized plant growth regulators. It participates in a variety of stress responses and developmental processes. Genetic studies in Arabidopsis have defined a number of genes in the ethylene signal transduction pathway. Isolation of two of these genes has revealed that plants sense this gas through a combination of proteins that resemble both prokaryotic and eukaryotic signaling proteins. Ethylene signaling components are likely conserved for responses as diverse as cell elongation, cell fate patterning in the root epidermis, and fruit ripening. Genetic manipulation of these genes will provide agriculture with new tools to prevent or modify ethylene responses in a variety of plants.
