• The world's low-lying rice (Oryza sativa) cultivation areas are under threat of submergence or flash flooding due to global warming. Rice plants manifest a variety of physiological and morphological changes to cope with submergence and hypoxia, including lowering carbohydrate consumption, inhibiting shoot elongation, and forming a thicker leaf gas film during submergence. Functional studies have revealed that submergence tolerance in rice is mainly determined by an ethylene response factor (ERF) transcription factor-encoding gene, namely SUBMERGENCE 1A-1 (SUB1A-1) located in the SUB1 quantitative trait locus. The SUB1A-1-dependent submergence tolerance is manifested through hormonal signaling involving ethylene, gibberellic acid, brassinosteroid, auxin and jasmonic acid. Considerable progress has been made toward the introduction of SUB1A-1 into rice varieties through a conventional marker-assisted backcrossing approach. Here, we review the recent advances in the physiological, biochemical and molecular dynamics of rice submergence tolerance mediated by the ‘quiescence strategy’. Thus, the present review aims to provide researchers with insights into the genetics of rice submergence tolerance and future perspectives for designing submergence-resilient plants for sustainable agriculture under the uncertainties of climate change. •Rice plants having SUB1A-1 endure submergence through a quiescence strategy.•SUB1A-1 mediates inhibition of levels and signaling of ethylene, gibberellin and auxin.•SUB1A-1 increases brassinosteroid biosynthesis and signaling, and JA responsiveness.•SUB1A-1 activates leaf gas film formation and reduces carbohydrate catabolism.•Submergence-tolerant wild rice genotypes lack SUB1A.
