Light is the primary element that plants need to grow, and UV rays, the harmful part of solar radiation, can decrease plant growth by slowing down the metabolic rate of photosynthesis. There are three different types of ultraviolet (UV) radiation, each with a distinct waveband: UV-A (315–400 nm), UV-B (280–315 nm), and UV-C (280 nm). Wavelength, intensity, and exposure to light have a big impact on plant quality and growth. Photoreceptors such as UV Resistance Locus 8 (UVR8), which promotes adaptation to UV-B stress, control how plants interact with UV radiation. While it is well established that UV in large amounts can harm production and quality metrics, some studies suggest that UV in moderate doses may promote biomass growth and the creation of beneficial chemicals that primarily absorb UV. It is well known that UV radiation causes differences in plant architecture, which are significant in ornamental crops and raise their economic value. Increased resistance to insects and diseases and a reduction in postharvest quality depletion are two effects of abiotic stress brought on by UV exposure. This review emphasises how UV may affect plant quality, growth, photomorphogenesis, and resistance to abiotic and biotic stress.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
