When plants are submerged by water they suffer from hypoxia. Although it has long been known that ethylene accumulates in submerged plants, its role in plant tolerance to hypoxia remained elusive. Recently, Hartman et al. described a mechanism that explains the role of ethylene in oxygen sensing and signaling.

乙烯信号控制植物中的快速氧气感测。

当植物被水淹没时，它们会遭受缺氧。尽管早就知道乙烯在淹没的植物中积累，但其在植物对缺氧的耐受性中的作用仍然难以捉摸。最近，Hartman等人。描述了解释乙烯在氧气感测和信号传导中的作用的机制。
