Phylogenetic of Trichaptum Based on Mitochondrial Small Subunit rDNA Sequences: Ko, Kwan Soo , Jung, Hack Sung; J. Microbiol. 1997;35(4):259-263.

Abstract: To study the phylogenetic relationships of species of Trichaptum and to infer intraspecific dibergence of T. abietinum, partial mitochondrial small subunit rDNA sequences were determined. Six strains of T. abietinum, two of T. biforme, and one of T. fusco-violaceum were examined. Parsimony and distance analyses showed that each Trichaptum species forms a distinct group and that T. abietinum consists of two or more subgroups. Strains from North America were distantly related to one another but the European strain formed an independent group with three Korean strains, suggesting the possibility that Korean taxa may be phylogenetically closer to European taxa than to North American taxa.

Sequence Comparison of Mitochondrial Small Subunit Ribosomal DNA in Penicillium: Soon Gyu Hong , Yoon-Dong Park , Wonjin Jeong , Kyung Sook Bae; J. Microbiol. 2000;38(2):62-65.

Abstract: Partial sequence comparisons of mitochondrial small subunit rDNA (mt SSU rDNA) were used to examine taxonomic and evolutionary relationships among seven Penicillium species: two monoverticillate species, two biverticillate species, and three terverticillate species. Amplified fragments of mt SSU rDNA highly varied among seven species in size, suggesting the existence of multiple insertions or deletions in the region. A phylogenetic tree was constructed by exhaustive search of parsimony analysis. The phylogenetic tree distinguished two statistically supported monophyletic groups, one for two monoverticillate species and the other for three terverticillate species and one biverticillate species, P. vulpinum. The phylogenetic relationship of P. waksmanii, the biverticillate species, was not clear.
