Persistently cold environments constitute one of our world's largest ecosystems, and
microorganisms dominate the biomass and metabolic activity in these extreme …

In dense plant populations, individuals shade each other resulting in a low‐light habitat that
is enriched in far‐red light. This light quality gradient decreases the efficiency of the …

Dr. Harris has played a major role in the development of this organism as a model system.
Her previous version of the Chlamydomonas Sourcebook which published in 1989, has …

Blue and red lights differently regulate leaf photosynthesis. Previous studies indicated that
plants under blue light generally exhibit better photosynthetic characteristics than those …

The persistent low temperature that characterize polar habitats combined with the
requirement for light for all photoautotrophs creates a conundrum. The absorption of too …

In plants and algal cells, changes in light intensity can induce intrachloroplastic and
retrograde regulation of gene expression in response to changes in the plastoquinone redox …

Abstract The McMurdo Dry Valleys of Antarctica harbor numerous permanently ice-covered
lakes, which provide a year-round oasis for microbial life. Microbial eukaryotes in these …

Permanently cold habitats dominate our planet and psychrophilic microorganisms thrive in
cold environments. Environmental adaptations unique to psychrophilic microorganisms …

Abstract The Antarctic green alga Chlamydomonas sp. UWO 241 (UWO 241) is adapted to
permanent low temperatures, hypersalinity, and extreme shade. One of the most striking …

Carotenoids are essential components of photosynthetic organisms including land plants,
algae, cyanobacteria, and photosynthetic bacteria. Although the light-mediated regulation of …
