Abstract:
As sessile organisms, plants cannot run away from unfavourable growth conditions. In order to survive stress conditions, for example flooding stress, they have evolved multiple adaptational mechanisms. Flooding stress restricts gas diffusion in and out of the plant cells, and subsequently leads to oxygen deficiency inside the plants. Plants can react to flooding with two strategies. On one hand, they can avoid the occurrence of oxygen deficiency inside by anatomical and morphological adaptations. These adaptations are mainly mediated by the gaseous plant hormone ethylene. On the other hand, they can also survive with oxygen deficiency, at least for some time. This adaptation includes the rearrangement of primary metabolism, for example through induction of fermentation. This transcriptional rearrangement is mediated by a set of transcription factors whose protein abundance directly depends on the oxygen concentration inside the plant cells.
