TLDR
Advances have been made in elucidating possible oxygen-sensing systems and regulatory components that are involved in these responses, which lead to the induction of a plant-specific and energy-conserving pathway of sucrose degradation, which decreases oxygen consumption and improves plant performance.About:

Flooding Stress: Acclimations and Genetic Diversity
TL;DR: This exploration of natural variation in strategies that improve O(2) and carbohydrate status during flooding provides valuable resources for the improvement of crop endurance of an environmental adversity that is enhanced by global warming.
Journal ArticleDOI
Flooding tolerance: suites of plant traits in variable environments
TL;DR: Evolution of 'suites of traits' are evident in wild wetland species and in rice, adapted to particular flooding regimes, and among traits for improved internal aeration and recovery are those for anoxia tolerance and recovery.
Journal ArticleDOI
A variable cluster of ethylene response factor-like genes regulates metabolic and developmental acclimation responses to submergence in rice.
TL;DR: It is demonstrated that the Sub1 region haplotype determines ethylene- and GA-mediated metabolic and developmental responses to submergence through differential expression of Sub1A and Sub1C, which dampens ethylene production and GA responsiveness.
Journal ArticleDOI
Chemical root to shoot signaling under drought
TL;DR: Current knowledge of, and advances in, research on chemical signals that are sent from roots under drought are described and the contribution of these different potential signals is discussed within the context of their role in stress signaling.
Journal ArticleDOI
Organization and regulation of mitochondrial respiration in plants.
TL;DR: Recent advances in understanding of the mitochondrial respiratory machinery of cells are described, including the presence of a classical oxidative phosphorylation system linked to the cytosol by transporters discussed alongside nonphosphorylating bypasses that alter the efficiency of ATP synthesis and play a role in oxidative stress responses in plants.

Oxygen sensing and molecular adaptation to hypoxia
H F Bunn,Robert O. Poyton +1 more
TL;DR: Redox chemistry appears to play a critical role both in the trans-activation of oxygen-responsive genes in unicellular organisms as well as in the activation of HIF-1, which is required for the hypoxic induction of physiologically important genes.

OXYGEN DEFICIENCY AND ROOT METABOLISM: Injury and Acclimation Under Hypoxia and Anoxia
TL;DR: This review examines how roots are injured by O2 deficiency and how metabolism changes during acclimation to low concentrations of O2, and indicates that selective sacrifice of cells may resemble programmed cell death and is distinct from cell death caused by anoxia.

Metabolic Profiling Allows Comprehensive Phenotyping of Genetically or Environmentally Modified Plant Systems
Ute Roessner,Alexander Luedemann,Doreen Brust,Oliver Fiehn,Thomas Linke,Lothar Willmitzer,Alisdair R. Fernie +6 more
TL;DR: The use of metabolic profiling in conjunction with datamining tools as a technique for the comprehensive characterization of a plant genotype is demonstrated.

Metabolism and functions of gamma-aminobutyric acid
TL;DR: Experimental evidence supports the involvement of GABA synthesis in pH regulation, nitrogen storage, plant development and defence, as well as a compatible osmolyte and an alternative pathway for glutamate utilization.

Cellular Mechanism of Oxygen Sensing
TL;DR: A deeper understanding of the cellular mechanisms of O2 sensing will facilitate the development of new pharmacological tools effective in the treatment of diseases such as stroke or myocardial ischemia caused by localized deficits of O 2.
