Radiation stress syndrome
nounPronunciation: /ˌreɪdiˈeɪʃən ˈstres ˈsɪndrəʊm/
A complex physiological disorder resulting from exposure to excessive or damaging electromagnetic radiation including ultraviolet-a, visible light excess, or ionizing radiation, causing DNA damage and molecular dysfunction. This syndrome manifests through cellular membrane disruption, mutation accumulation, and impaired developmental processes.
Plain English
Plant damage caused by excessive or harmful radiation exposure affecting cellular structures and genetic material.
Etymology & History
Usage
"Radiation stress syndrome in mountainous regions with high altitude exposure causes photomorphogenic changes and reduced biomass accumulation."
Style guide notes: Specify radiation type and wavelength when discussing radiation stress syndrome to ensure clarity regarding causative mechanisms.
