Identification of ABA-Mediated Genetic and Metabolic Responses to Soil Flooding in Tomato ( L. Mill).

Soil flooding is a compound abiotic stress that alters soil properties and limits atmospheric gas diffusion (O and CO) to the roots. The involvement of abscisic acid (ABA) in the regulation of soil flooding-specific genetic and metabolic responses has been scarcely studied despite its key importance as regulator in other abiotic stress conditions. To attain this objective, wild type and ABA-deficient tomatoes were subjected to short-term (24 h) soil waterlogging.
