Excess of water affects plant growth and metabolism dramatically. Limited oxygen availability and changes in soil redox potential and pH result in energy shortage, nutritional disturbances, phytotoxicity, and oxidative injury to plants. This chapter reviews basic mechanisms exploited by plants to combat these damages. This includes constitutive or stress-induced aerenchyma development, adventitious root formation, changes to metabolic profile and energy use strategies, changes in antioxidant pool, and increased tolerance to elemental and organic phytotoxins. We also discuss signal transduction pathway mediating plant adaptive responses to waterlogging, with the main emphasis on Sub1 gene cluster. We then discuss the recent progresses in the quantitative traits locus (QTL) mapping for some key traits associated with waterlogging and submerging stress tolerance, how the combined network of hormones and metabolites is involved in regulation of plant adaptive responses to waterlogging, and how this knowledge should guide the breeding of tolerant varieties or developing novel sources of waterlogging-tolerant crops are also illustrated. Finally, we discuss methods to explore and develop waterlogging tolerant genotypes.
