About this Research Topic
Polyamines are small, ubiquitous molecules found in all living organisms, playing crucial roles in plant growth, development, and responses to both abiotic and biotic stresses. Despite their well-established involvement in fundamental plant physiological processes, polyamines are still emerging as key regulators in the intricate molecular networks that govern how plants adapt to environmental challenges. This Research Topic aims to highlight recent advances in understanding the roles of polyamines, bridging fundamental discoveries with potential applications in crop improvement and stress resilience.
Polyamines such as putrescine, spermidine, and spermine are involved in diverse physiological processes, including cell division, flowering, senescence, and stress response. They interact with other molecular signals like reactive oxygen species (ROS), nitric oxide (NO), and phytohormones, creating complex signaling networks that help plants survive and thrive under adverse conditions. Their roles in both abiotic stress (such as drought, salinity, heat, and cold) and biotic stress (including pathogen and pest interactions) make polyamines a versatile and promising area of study, especially in the context of climate change and increasing agricultural challenges.
Although polyamines have been the subject of research for several decades, recent advances in molecular biology, genomics, and biotechnology have brought new insights into how they function at cellular and systemic levels. The manipulation of polyamine biosynthesis pathways through genetic engineering offers exciting potential for enhancing stress tolerance and improving crop yield. This Research Topic seeks to foster a deeper understanding of polyamine signaling, their biosynthesis, and their practical applications in developing resilient plant varieties.
The goal of this collection is to encourage research that advances the current knowledge of polyamines and their multifaceted roles in plant science. Submissions that explore polyamines' interaction with other signaling molecules, their regulatory roles in developmental processes, and their contribution to stress tolerance at molecular, physiological, and ecological levels are particularly welcome.
We invite submissions of original research, reviews, mini-reviews, and methods papers covering the following, but not limited to:
· Polyamine biosynthesis and metabolic regulation
· Role of polyamines in abiotic stress tolerance (drought, salinity, heat, cold)
· Polyamines and biotic stress resistance (pathogen defense, pest management)
· Polyamines and priming plant immunity
· Polyamines and functional plant microbiome
· Cross-talk between polyamines and other signaling molecules (ROS, NO, phytohormones)
· Genetic engineering and biotechnological applications of polyamines for crop improvement
· Comparative studies of polyamine function across different plant species
· Role of polyamines in plant development, senescence, and flowering
This Research Topic seeks to gather studies that provide novel mechanistic insights and practical applications, contributing to a better understanding of polyamines' roles 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 leveraged to meet the demands of a changing environment.
