Abstract Number: 4116
Session = A study is underway to examine the phylogenetic relations between Arabidopsis thaliana populations around the world. We are examining 1) the geographic location of the most likely primogenitor population of A. thaliana, 2) the hypothesis that A. thaliana is not native to North America and was conveyed there from Europe, 3) the morphologic versus genetic changes over evolutionary time, and 4) whether various A. thaliana populations may be considered true races. Polymorphic DNA fragments (SSLP's) amplified by PCR are being used as the basis for phylogenetic comparisons between populations. Initial data suggests North American strains are closely related to each other as well as some European strains. Also the Japanese strain Tsu appears most phylogenetically divergent of all the populations studied.
