A five-year effort to reconstruct the evolutionary relationships among all green plants has resulted in the most complete "tree of life" of any group of living things on the planet, including animals.

The up-to-date family tree has revealed several surprises about the evolution of green plants, such as how they emerged from the sea onto land and how they are related to the four other major kingdoms: the brown plants, the red plants, the fungi and the animals.

Specifically, the team has overturned the traditional belief that the so-called "land-plant invasion" was led by seawater plants. Instead, the research team has found that primitive freshwater plants provided the ancestral stock from which all green plants now on land are descended, and that this ancestor spawned every green plant now alive on earth.

This knowledge will help scientists in a broad range of disciplines, from those trying to develop new and better crops to those prospecting for new medicines. (exerpt from University of California press release)

A sampling of coverage of "Deep Green" by the media

Science Magazine June 13th, 2003 (archived)
Thus for plant taxonomists the next 5 years promise to be a data gold rush. Several other projects, independently funded but interconnected, are delving into less well- covered aspects of the field. One, called Deep Gene, will help plant experts make use of plant genomics information and vice versa...
Tree of Life Grant
A new grant will fund research to help reconstruct the evolutionary relationships of green plants using comparative genomics. This research is part of a nation-wide collaborative effort involving 6 universities. Through its new "Assembling the Tree of Life" program, the National Science Foundation is hoping to stimulate a detailed reconstruction of the phylogeny of all living things, to better understand the history of life and advance human needs including discovery of new drugs, tracking pathogens, and conservation of biodiversity.

"The highly successful Deep Green project to construct a "tree of life" for the green plants has ended, but it has seeded new projects to strengthen the branches and root the tree more firmly in new genetic and fossil data.

"By finding that ferns and horsetails are more closely related to each other than to seed plants, Pryer and colleagues have "added a new branch to the tree," says Brent Mishler of the University of California, Berkeley"

"Homologies, notes Brent Mishler, a professor of integrative biology at the University of California at Berkeley, can arise in anatomical structures, such as the three-part body of the insect, or in the "lettering" of the genetic code"
