Polyamines are small, ubiquitous molecules found in all living organisms, playing a key role in plant growth and development and responses to both abiotic and biotic stresses. Despite their well-established involvement in fundamental plant physiological processes, polyamines continue to emerge as key regulators in the complex molecular networks that regulate how plants adapt to environmental challenges. The aim of this Research Topic is to highlight recent advances in understanding the role of polyamines, linking fundamental discoveries with potential applications in crop improvement and stress resistance.
Polyamines such as putrescine, spermidine, and spermine are involved in a variety of physiological processes, including cell division, flowering, aging, and the stress response. They interact with other molecular signals, such as reactive oxygen species (ROS), nitric oxide (NO), and phytohormones, to form complex signaling networks that help plants survive and thrive in adverse conditions. Their role in both abiotic stress (such as drought, salinity, heat and cold) and biotic stress (including pathogen and pest interactions) makes polyamines a versatile and promising area of research, particularly in the context of climate change and growing challenges in agriculture.
Although polyamines have been the subject of research for several decades, recent advances in molecular biology, genomics, and biotechnology have provided new insights into their functioning at the cellular and systemic levels. Manipulating polyamine biosynthetic pathways through genetic engineering offers exciting potential to increase stress tolerance and improve crop yields. The aim of this research topic is to deepen the understanding of polyamine signaling, its biosynthesis and its practical applications in the development of resistant plant varieties.
The purpose of this collection is to encourage research that advances current knowledge of polyamines and their multifaceted role in plant sciences. We especially welcome reports on the interactions of polyamines with other signaling molecules, their regulatory role in developmental processes, and their contribution to stress tolerance at the molecular, physiological and ecological levels.
We encourage you to submit original research, reviews, mini-reviews and methodological articles covering, among others:
· Polyamine biosynthesis and regulation of metabolism
· The role of polyamines in tolerance to abiotic stress (drought, salinity, heat, cold)
Polyamines and resistance to biotic stress (defense against pathogens, pest control)
· Polyamines and priming plant immunity
· Polyamines and the functional plant microbiome
· Crosstalk between polyamines and other signaling molecules (ROS, NO, phytohormones)
· Genetic engineering and biotechnological applications of polyamines in crop improvement
· Comparative studies of the functions of polyamines in various plant species
· The role of polyamines in the development, aging and flowering of plants
The aim of this Research Topic is to bring together research that provides novel mechanistic insights and practical applications, contributing to a better understanding of the role of polyamines in plant biology and opening pathways for innovation in sustainable agriculture. We encourage interdisciplinary contributions that integrate physiology, molecular biology, genetics, and biotechnology to explore how polyamines can be used to meet the demands of a changing environment.
