Polyamines (PAs) are natural aliphatic amines involved in many physiological processes almost all living organisms, including responses to abiotic stresses and microbial interactions. This review presents the profuse evidence that relates changes polyamines levels during biotic model cultivable species within Leguminosae, examines their potential roles functioning of symbiotic interactions with nitrogen fixing bacteria arbuscular mycorrhizae. The family Leguminosae constitutes an economically ecologically key botanical group for humans, being also regarded as most important protein source livestock. ability legumes establish mycorrhizae fungi, gives some legume able exploit molecular machinery “pioneer” attributes, better competition nutrient-poor soils higher adaptation restricted environments. However, crops may be affected by climate change-derived environmental stresses, whereby maintaining yields safe from adverse conditions is probably one biggest challenge facing modern agriculture. Therefore, obtaining vigorous genotypes tolerance stressors has turned increasingly biotechnological target. At this scenario, PAs can play role, genetic manipulation crop plants genes encoding polyamine PA biosynthetic pathway enzymes envisioned a strategy achieve improved stress performance.
