Introduction Ultraviolet-B (UV-B) radiation (280–315 nm) is a natural component of sunlight that has profound effects on plant growth, development, and metabolism. Although UV-B constitutes only a small fraction of the solar spectrum reaching the Earth’s surface, it has significant biological implications due to its high energy levels. With increasing environmental concerns such as ozone READ MORE

Understanding Polyamines: The Key to Plant Stress Response Mechanisms
Polyamines (PAs) are low molecular weight, aliphatic polycations ubiquitously present in all living organisms. They play crucial roles in a variety of physiological processes in plants, including growth, development, and stress responses. The primary polyamines found in plants are putrescine (Put), spermidine (Spd), and spermine (Spm). Their ability to interact with nucleic acids, proteins, and READ MORE
