Montana State team finds Yellowstone alga that detoxifies arsenic

BOZEMAN, Mont. -- Arsenic may be tough, but scientists have found a Yellowstone National Park alga that's tougher. The alga -- a simple one-celled algae called Cyanidioschyzon -- thrives in extremely toxic conditions and chemically modifies arsenic that occurs naturally around hot springs, sa...

Green alga genome project catalogs carbon capture machinery

WALNUT CREEK, -The genome analysis of a tiny green alga has uncovered hundreds of genes that are uniquely associated with carbon dioxide capture and generation of biomass. Among the 15,000-plus genes revealed in the study are those that encode the structure and function of the specialized organell...

Billion-year revision of plant evolution timeline may stem from discovery of lignin in seaweed

...Martone and colleagues describe using powerful chemical and microscopic anatomy techniques to identify and localize lignin within cell walls of a red alga that thrives along the wave-swept California coast. Martone conducted the work described in the paper while a graduate student and postdoctoral resear...
