Continuous depletion of the stratospheric ozone layer has resulted in an increase in
ultraviolet-B (UV-B; 280–315 nm) radiation reaching the Earth's surface. UV radiation has …

The photoinactivation (also termed photoinhibition or photodamage) of Photosystem II (PSII)
and the counteracting repair reactions are fundamental elements of the metabolism and …

A radiative transfer model is used to quantitatively investigate aspects of the martian
ultraviolet radiation environment, past and present. Biological action spectra for DNA …

Nitrogen (N) limitation significantly increased the sensitivity of photosynthesis to inhibition by
ultraviolet radiation (UV) in two estuarine dinoflagellates, Akashiwo sanguinea …

The surface of early Earth was exposed to both UVC radiation (< 280nm) and higher doses
of UVB (280–315 nm) compared with the surface of present day Earth. The degree to which …

Current ambient UV-B levels can significantly depress productivity in aquatic habitats,
largely because UV-B inhibits several steps of photosynthesis, including the photooxidation …

pigmentation under solar radiation in a laboratory system and in the natural habitat during a …

▪ Abstract Ozone depletion by anthropogenic gases has increased the atmospheric
transmission of solar ultraviolet-B radiation (UV-B, 280–315 nm). Our understanding of the …

Marine microalgae (152 species, 206 strains) from 12 classes were examined for the
presence of UVA-and UVB-absorbing compounds. Cultures were grown under white …

Recent evidence from algal physiology and molecular biology confirms that photoinhibition
