Polyamines (PAs) are natural aliphatic amines involved in many physiological processes in almostall living organisms, including responses to abiotic stresses and microbial interactions. Onother hand, the family Leguminosae constitutes an economically and ecologically key botanicalgroup for humans, being also regarded as the most important protein source for livestock. Thisreview presents the profuse evidence that relates changes in PAs levels during responses tobiotic and abiotic stresses in model and cultivable species within Leguminosae and examinesthe unreviewed information regarding their potential roles in the functioning of symbioticinteractions with nitrogen-fixing bacteria and arbuscular mycorrhizae in this family. As linkingplant physiological behavior with ?big data? available in ?omics? is an essential step to improveour understanding of legumes responses to global change, we also examined integrativeMultiOmics approaches available to decrypt the interface legumes-PAs-abiotic and biotic stressinteractions. These approaches are expected to accelerate the identification of stress tolerantphenotypes and the design of new biotechnological strategies to increase their yield andadaptation to marginal environments, making better use of available plant genetic resources.
