title: New insights into the metabolic and molecular mechanism of plant response to anaerobiosis.
abstract: Under anaerobic conditions, plants apply a wide spectrum of precise adaptive strategies responding to several critical challenges. The ability of efficiently sensing the oxygen presence demonstrates the existence of both direct and indirect ways of perception. The subsequent coordinate metabolic reassessment is currently under study. The complex molecular response implicates not only transcriptional and translational regulation of specific genes but also posttranscriptional and posttranslational regulatory mechanisms, each and all integrating the metabolic settings. Furthermore, the accumulation of typical metabolites during low oxygen stress condition is a key factor that suggests some critical topics in the regulation of metabolic pathways. Here, we summarize the main routes for adaptive behavior during oxygen depletion, from oxygen availability perception to recently discovered molecular mechanisms and metabolic adaptations.
