| identification, classification and phylogeny of the aspergillus section nigri inferred from mitochondrial cytochrome b gene. | the partial mitochondrial cytochrome b gene from 32 strains of 12 species belonging to aspergillus section nigri was amplified by the polymerase chain reaction and sequenced directly. using 402 nucleotide characters, nucleotide-based and amino acid-based phylogenetic trees were inferred and the genetic divergence among the species was evaluated. based on analyses of the 402-bp nucleotide and 133-amino acid sequences, strains were divided into 11 dna types and five amino acid types. aspergillus n ... | 2001 | 11425482 |
