UV-B Radiation Induces Root Bending Through the Flavonoid-Mediated Auxin Pathway in Arabidopsis
Frontiers in Plant Science, 2018 Ultraviolet (UV)-B radiation-induced root bending has been reported; however, the underlying mechanisms largely remain unclear. Here, we investigate whether and how auxin and flavonoids are involved in UV-B radiation-induced root bending in Arabidopsis ...

Journal of Plant Interactions, 2017 Prunella vulgaris plants (full-bloom stage) were subjected to short-term (15 days) UV-B radiation in a growth chamber. UV-B radiation was effective at enhancing morphological and biomass characteristics and decreasing chlorophyll contents of P. vulgaris.

Ambient UV-B radiation causes deformities in amphibian embryos [PDF]
Proceedings of the National Academy of Sciences, 1997 There has been a great deal of recent attention on the suspected increase in amphibian deformities. However, most reports of amphibian deformities have been anecdotal, and no experiments in the field under natural conditions have been performed to investigate this phenomenon.

Elevated UV-B radiation reduces genome stability in plants
Nature, 2000 Long-term depletion of the stratospheric ozone layer contributes to an increase in terrestrial solar ultraviolet-B radiation$^{1,2,3}$. This has deleterious effects on living organisms, such as DNA damage$^{4,5}$. When exposed to elevated ultraviolet-B radiation (UV-B; 280–315 nm), plants display a wide variety of physiological and morphological ...

Ultraviolet-B radiation induces cell death in root tips and reprograms metabolism in Arabidopsis
Biologia Plantarum, 2020 Ultraviolet-B (UV-B) radiation inhibits root system growth, however, the influence of UV-B radiation on the regulation of root development remains unclear.

UV-B radiation and soil microbial communities [PDF]
Nature., 2003 Soil microorganisms regulate the supply of nitrogen to plants and so are important controllers of plant productivity and ecosystem carbon sequestration. Johnson et al.1 report that exposure of a subarctic heath ecosystem to increased ultraviolet-B (UV-B) irradiation causes a drastic decline in the mass ratio of C:N in soil microorganisms, which would ...
