The adverse effect of low intensity, small band UV-B irradiation (λ = 305 ± 5 nm, I = 300 mW m−2) on PS II has been studied by comparative measurements of laser flash-induced changes of the absorption at 325 nm, ΔA325(t), as an indicator of redo

Since Antarctic plants experience a wide range of ultraviolet (UV) exposure, the pigment content of Antarctic algae (Palmaria decipiens (Reinsch) Ricker, Enteromorpha bulbosa (Suhr) Montagne, Prasiola crispa (Lightf.) Kutz. sp. antarctica (Kutzing) K

Adaptations to severe environmental conditions were studied in the only recorded continental Antarctic hepatic, Cephaloziella exiliflora (Tayl.) Steph. During the summer growing season Antarctic plants melt out and many are exposed fully to the sun.

Flash-induced absorbance measurements at 830 nm on both nanosecond and microsecond timescales have been used to characterise the effect of ultraviolet light on Photosystem II core particles. A combination of UV-A and UV-B, closely simulating the spec

The kinetics of P680(+) reduction in oxygen-evolving spinach Photosystem II (PS II) core particles were studied using both repetitive and single-flash 830 nm transient absorption. From measurements on samples in which PS II turnover is blocked, we es

Variation in leaf pigmentation from green to ginger is observed for Ceratodon purpureus (Hedw.) Brid. in Antarctica. Electron microscopy of ginger and green leaves reveals less thylakoid stacking, a response to greater light exposure, in the ginger l

Antarctic bryophytes survive frozen over winter and grow fully exposed to sunlight in summer. Preliminary observations of quantum yields, light saturated photosynthetic rates and variable fluorescence of bryophytes suggested that photoinhibition was

Terrestrial vegetation on the Bailey and Clark Peninsulas, East Antarctica (66°17’S, 100°32’E), consists entirely of algae, lichens and bryophytes. Ground cover is sparse and low productivity so easily attributed to the combined effects of wate

Plastoquinone-9 (PQ-9) is the only non-protein component in the photosynthetic electron transport pathway of thylakoids. During transport the benzoquinone ring is reduced to form plastoquinol which is thought to be the mobile charge carrier transferr
