Phylogenetic analysis of Antrodia and related taxa based on partial mitochondrial SSU rDNA sequences.

摘要

Sequences of mitochondrial SSU rDNA were obtained from six species of Antrodia and related fungal taxa to reveal their phylogenetic relationships. Phylogenetic analysis showed that the species of Antrodia did not cluster into a single clade. Brown rot fungi were separated into two main groups through which Antrodia was dispersed. Antrodia sinuosa, A. serialis, A. heteromorpha and A. malicola clustered with Perenniporia, Fomitopsis, Piptoporus, Daedalea and Melanoporia within one group of brown rot fungi, while A. carbonica and A. vaillantii clustered with Oligoporus, Gloeophyllum and Auriporia within the other group of brown rot fungi, indicating that Antrodia is a heterogeneous genus and that brown rot fungi have evolved convergently.
