Description
The main goal of this research is to examine systematics of claviceps associated with morning glories. This study tests two hypotheses reflecting evolutionary relationships of these fungi :(1) fungal-morning glory relationships may reflect biogeographic patterns, (2) comparative methods may detect congruency in host/symbiont phylogenies. This study reports largest subunit of RNA polymeraseII (rpb1) sequence data. Hosts morning glories of Amnicola clade are found in different geographical regions eliminating biogeographic hypothesis. On comparing host/symbiont phylogenies, congruence suggested ancient relationship. However, minor genetic divergence indicated by sequence data suggests that claviceps found within morning glories of different regions, could be single species.
