Reactive oxygen species (ROS) can attack a diverse range of targets to exert antimicrobial
activity, which accounts for their versatility in mediating host defense against a broad range …

Carotenoids are known to play important roles in plants as antioxidants, accessory light‐
harvesting pigments, and attractants for pollinators and seed dispersers. A new function for …

During photosynthesis carotenoids normally serve as antenna pigments, transferring singlet
excitation energy to chlorophyll, and preventing singlet oxygen production from chlorophyll …

Carotenoids play a crucial protective role in photosynthetic organisms as quenchers of
singlet oxygen (1O2). This function occurs either via a physical mechanism involving thermal …

The red heterobasidiomycetous yeast Xanthophyllomyces dendrorhous (perfect state of
Phaffia rhodozyma) contains a novel type of carotenoid biosynthetic enzyme. Its structural …

Singlet oxygen is the primary agent of photooxidative stress in microorganisms. In
photosynthetic microorganisms, sensitized generation by pigments of the photosystems is …

Questions: Does herbivores' diet per se affect their immunocompetence? Do other fitness
measures vary accordingly? Can the observed differences be explained by the chemical …

β‐Carotene and derivatives are important pigments in plant photosynthesis. They are found
not only in green plants but also accumulate in archea, prokaryotes and fungi. For β …

A 37-kb photosynthesis gene cluster was sequenced in a photosynthetic bacterium
