Ceratocystiopsis: a reappraisal based on molecular criteria
Analysis of partial rDNA sequences from both the small and large subunit genes of species of Ceratocystiopsis suggests they represent a polyphyletic group. Therefore the production of falcate-like ascospores, the key feature of this genus, is an example of convergent evolution. The partial rDNA sequ...

| description | Analysis of partial rDNA sequences from both the small and large subunit genes of species of
Ceratocystiopsis suggests they represent a polyphyletic group. Therefore the production of falcate-like ascospores, the key feature of this genus, is an example of convergent evolution. The partial rDNA sequences also show that the majority of
Ceratocystiopsis spp. can be placed in
Ophiostoma along with
Certocystis ips, a conclusion supported at the 100% confidence level by bootstrap analysis. Therefore we formally reduce
Ceratocystiopsis to synonymy with
Ophiostoma and provide the necessary new combinations in
Ophiostoma. However,
C. proteae, C. falcata, and
C. alba are shown to have a very distant relationship with
Ophisotoma, and their taxonomic position remains unresolved. |
