During the last few decades, there has been considerable concern over the depletion of
stratospheric ozone as a result of anthropogenic pollutants. This has resulted in a …

Origin of life was never be thought without considering the role of UV radiation but once the
“boon”, is slowly becoming “curse” for life. Plants are exposed to many factors but the …

Chlorophyll (Chi) a fluorescence has become an important non-invasive tool to investigate
the utilization and dissipation of absorbed light energy in photosynthesis. In particular …

We studied the effect of UV-B radiation (280− 320 nm) on the donor-and acceptor-side
components of photosystem II in the cyanobacterium Synechocystis sp. PCC 6803 by …

The Structure and Function of PSII B. Inhibition of PSII Electron Transport by UV-B 1. The …

Abstract Ultraviolet-B (UV-B) radiation can have a negative impact on the growth and
development of plants. Plants tolerant to UV-B alleviate these effects using UV-screening …

Inhibition of photosystem II electron transport by UV-B radiation has been studied in isolated
spinach photosystem II membrane particles using low-temperature EPR spectroscopy and …

The primary processes of photosynthesis lead to transformation of solar radiation into
electrochemical Gibbs energy-the driving force for life on Earth. These intricate and …

The primary target of damage during photoinhibition of oxygenic photosynthesis is
Photosystem II (PS II). The molecular processes which underlie this vulnerability almost …

Ambient ultraviolet-B (UV-B) radiation potentially impacts the photosynthetic performance of
high Arctic plants. We conducted an UV-B exclusion experiment in a dwarf shrub heath in …
