Green Plant Phylogeny Research and the Sixth International Phycological Congress
in Leiden, The Netherlands

1-16 August 1997

The Green Plant Phylogeny Research Coordination Group (GPPRCG) was well represented at the Sixth International Phycological Congress held 1-16 August 1997 in Leiden, The Netherlands. The GPPRCG was, in part, an inspiration for the symposium titled "Global Consortia in exploring algal evolution: partnerships, process, and progress," convened by Mark Buchheim and Volker Huss. The whole concept of this symposium was discussed by the "green alga scientists" who met in a GPPRCG-sponsored workshop in conjunction with the Phycological Society of America annual meeting in Breckenridge, Colorado in 1995.

In this symposium, the green plants were the focus of the introductory talk by Russ Chapman ("The green plant phylogeny challenge: should botanists be more like physicists in the future?"). Green alga coverage at the Congress was not limited to this one symposium, and the following list includes many of the other green alga phylogeny presentations:
