Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

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.
