Re-interpreting plant morphological responses to UV-B radiation

There is a need to reappraise the effects of UV-B radiation on plant morphology in light of improved mechanistic understanding of UV-B effects, particularly andaltered root:shoot ratios. At the cellular level, ...

Plant Responses to UV-B Radiation

Research on plant UV-B responses commenced in earnest following discovery on photosynthesis and growth. A second phase of research centred on UV-B acclimation including to the conclusion that plants are well protec...

Effect of UV-B radiation on the content of UV-B absorbing compounds and photosynthetic parameters in Parmotrema austrosinense from two contrasting habitats

Abstract We studied the resistance of Parmotrema austrosinense to UV-B stress. We focused on the effects of a high dose UV-B radiation on the content of chlorophylls, carotenoids and UV-B screenin...

Endopolyploidy is a common response to UV-B stress in natural plant populations, but its magnitude may be affected by chromosome type.

BACKGROUND AND AIMS: Ultraviolet-B radiation (UV-B) radiation damages the DNA by synthetizing UV-B-protective compounds. Recent laboratory experiments in Arabidopsis and cucumber have indicated that plants...

Reprint of Efficient fungal UV-screening provides a remarkably high UV-B tolerance of photosystem II in lichen photobionts

Lichen photobionts in situ have an extremely UV-B tolerant photosystem II efficiency (Fv/Fm). We have quantified the UV-B-screening offered by the mycobiont with 1: intact or 2: removed cortices were exposed to 0.7...
