Flooding‐Stress in Plants

Abstract

Flooding is a stress that crop plants frequently encounter and results in huge economic losses. Studies on the effects of flooding at the molecular level may lead to improvements that will result in flood‐tolerant crop plants.

Key concepts

Flooding leads to a deprivation of oxygen in plants. Many plants respond to oxygen deprivation with adaptations that allow short‐term survival. Some plants show excellent tolerance to anoxia.

Keywords: oxygen deprivation; anoxia; hypoxia; flooding; plant stress; gene regulation

Protein synthesis in a maize primary root during anaerobic treatment. Fluorographs of native–sodium dodecyl sulfate (SDS) 2‐D polyacrylamide gels that were loaded with extracts from maize primary roots after the following treatments. (a) One hour pulse labelling with [3 H]‐leucine under aerobic conditions. (b–e) Pulse labelling with [3 H]‐leucine during the specified times under anaerobic conditions. The arrow labelled TPs indicates the position of the transition polypeptides. The unlabelled arrow indicates the position of alcohol dehydrogenase‐1 (ADH1). MW, molecular mass.
