Polyamines have been proposed to regulate multiple aspects of plant development and stress responses.
In most of the cases, they interact with other signaling pathways to exert their action. Here we describe
transcriptomic analyses that have lead to the identification of physiologically relevant interactions between
polyamines and other hormones, such as abscisic acid, during the response to abiotic stress. Overall, these studies
reinforce the premise that polyamines are regulatory signaling molecules which mediate by intricate cross-talks
with hormonal pathways in response to different environmental stimuli.
