Is parietin a UV-B or a blue-light screening pigment in the lichen Xanthoria parietina?
Lichens are extreme examples : the moist thalli of such species as Xanthoria candelaria and Rhizoplaca melanophthalma fully tolerated gradual or rapid freezing to -196 °C, and even after being stored for up to several years, almost immediately resumed normal photosynthetic rates when warmed and wetted.
The orange lichen Xanthoria turbinata is common and mostly grows on dead Salsola plants.
"These Xanthoria elegans lichens were flown on Expose-E and they are the best survivors we know," explains Demets.
