Green Plant Phylogeny Research Coordination Group
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,
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.

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.
