Elevated from plants to their own kingdom in 1969, they are extremely diverse yet difficult to observe, since many species cannot be grown in the lab. The gaps in our knowledge of the fungi are being filled by new efforts to catalog them, but one of the most interesting findings may come from analysis of their genomes. A new study shows that introns (intragenic regions) are more dynamic than previously thought.

Rubisco “Highly Tuned” for Fixing Atmospheric Carbon

June 22, 2006

Rubisco sounds like a brand of cracker or something, but it’s actually an air cleaner your life depends on. It’s an enzyme that fixes atmospheric carbon for use by photosynthetic microbes and plants. In doing so, it sweeps the planet of excess carbon dioxide – the greenhouse gas implicated in discussions of global warming – […]
