Plant Genetics 2003
Mechanisms of Genetic Variation
October 22-26, 2003 Snowbird Resort & Conference Center Snowbird, Utah
Chair: Venkatesan Sundaresan - University of California - Davis Vice-Chair: Rich Jorgensen - University of Arizona

Abstracts in PDF format

This conference on Plant Genetics will be the first of an annual series of specialist meetings sponsored by the ASPB. The focus of this meeting will be on the nature and mechanisms of genetic variation and their effects on evolution of plant form and function, as well as on plant speciation and crop domestication. The meeting will bring together speakers working on different organisms, and on different aspects and approaches to the problem, with the aim of achieving a synthesis of understanding to stimulate discussion and further research. Approximately 250 participants are expected. The secluded setting and schedule are designed to facilitate ongoing interaction between the presenters and attendees. All meals will be on-site and the speakers will be in attendance throughout the entire conference. Afternoons will be free for recreation, informal discussions and other activities. Participation by graduate students and young postdoctoral fellows is strongly encouraged, and discounted rates for registration and accommodation will be available.

There will be a keynote lecture followed by seven sessions dedicated to specific topics. Each session will feature three in-depth presentations plus shorter talks based on selected abstracts. Poster sessions will be scheduled daily.
