| Abstract/Contents: | "RAPD, RFLP and karyotyping have been used for taxonomic discrimination in the genus Colletotrichum. However these markers are unsuitable to infer evolutionary relationships. Although limited to the rDNA component, sequences in ITS1 and ITS2 regions have been used to derive phylogenetic relationships. For a genome-wide comparison, we chose essential housekeeping genes glutamine synthetase (GS) and glyceraldehyde phosphate dehydrogenase (GPDH) to test whether introns can be used for phylogenetic relationships. Primers designed to conserved coding regions flanking an intron in each of these genes amplified single bands in all four Colletotrichum while the GPDH intron was more variable. Sequence analysis showed a low frequency (~2%) of polymorphism in the GS intron of C. gloeosporioides isolates infecting Stylosanthes. Sequence polymorphisms between species were more frequent. We are comparing phylogenetic relations between and within species using intron sequences to those determined by ITS." |
