Abstract

Oxygen is a limiting factor for plant growth and development under submerged and waterlogged conditions. Plants are subjected to a varying range of oxygen concentrations, such as normoxia, hypoxia and anoxia which may differ over time and space. To endure oxygen deprivation, plants have evolved a series of morphological and anatomical adaptations, which have been extensively studied. However, metabolic reactions and molecular regulation under oxygen deprivation are not well understood. A comprehensive understanding of how plants respond to oxygen deficiency for stress tolerance and integrated approaches are imperative for developing anoxia and hypoxia tolerant varieties for the flood‐prone and waterlogged areas. In this review, adaptations and recent advances in biochemical and molecular approaches during oxygen deprivation have been discussed. Acquiring tolerance against anoxia and hypoxia is an active process consuming a considerable amount of plant resources for the functional maintenance of post‐anoxia escape strategies. Understanding of biochemical and molecular mechanisms may help devise contemporary molecular and traditional breeding approaches, and management strategies to improve anoxia‐hypoxia tolerance in crop plants.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
