Biodiversity of Asterina species on Neotropical host plants: new species and records from Panama
Mycologia, 2011Co-Authors: Tina Antje Hofmann, Meike PiepenbringAbstract:Two new species of the genus Asterina are described from living leaves collected in provinces Chiriqui and Bocas del Toro in western Panama. Asterina alloplecti on Alloplectus ichtyoderma (Gesneriaceae) differs from other Asterina on Gesneriaceae by its stalked appressoria and host relationship. Asterina compsoneurae on Compsoneura sprucei (Myristicaceae) can be distinguished from other members of Asterina on Myristicaceae by its larger ascomata, larger, prominently spinose ascospores and host relationship. New records for Panama are Asterina corallopoda from a new host plant species (Solanum trizygum, Solanaceae), A. diplopoda, A. ekmanii from a new host plant species (Gonzalagunia rudis, Rubiaceae), A. siphocampyli from a new host plant genus and species (Burmeistera vulgaris, Campanulaceae) and A. styracina from a new host-plant species (Styrax argenteus, Styracaceae). This study increases the number of species of Asterina known for Panama from 12 to 19 and the number of Asterinaceae from 14 to 21. Ast...

Phylogenetic relationships and new records of Asterinaceae (Dothideomycetes) from Panama
Fungal Diversity, 2010Co-Authors: Tina Antje Hofmann, Roland Kirschner, Meike PiepenbringAbstract:Asterinaceae are small obligately biotrophic pathogens growing superficially on living leaves of higher plants in tropical and subtropical regions worldwide. The species-rich but rarely studied ascomycete group has an uncertain placement within the Dothideomycetes because molecular data are missing completely up to now. Based on nuclear DNA from fresh material of five Asterina spp. and a related anamorphic stage from Panama, we present the first molecular phylogenetic hypothesis of the Asterinaceae within the Dothideomycetes. A combined SSU and LSU rDNA phylogenetic analysis shows that species of Asterina and its anamorphs form a well supported monophyletic clade within the Dothideomycetes with Venturiaceae as sistergroup. Three Asterina spp. included in the molecular study are new records for Panama and Central America with new records of host plant species: A. cestricola on Cestrum rugulosum (Solanaceae), A. weinmanniae on Weinmannia pinnata (Cunoniaceae) and A. zanthoxyli on Zanthoxylum scheryi (Rutaceae). A. cestricola and A. weinmanniae are illustrated here for the first time.

New species and records of Asterina from Panama
Mycological Progress, 2008Co-Authors: Tina Antje Hofmann, Meike PiepenbringAbstract:Species of Asterina are plant parasitic, bitunicate Ascomycetes which are particularly diverse in tropical regions. In the present publication, detailed descriptions, keys and illustrations of two newly described species and five newly recorded species of Asterina recently collected in Panama are presented. New species are Asterina gaiadendricola on Gaiadendron punctatum (Loranthaceae) and Asterina schlegeliae on Schlegelia parviflora (Schlegeliaceae) with their respective anamorphic Asterostomella and Mahanteshamyces states.

the phylogenetic status of paxillosida asteroidea based on complete mitochondrial dna sequences
Molecular Phylogenetics and Evolution, 2005Co-Authors: Mioko Matsubara, Miéko Komatsu, Takeyoshi Araki, Shuichi Asakawa, Shinichi Yokobori, Kimitsuna Watanabe, Hiroshi WadaAbstract:One of the most important issues in asteroid phylogeny is the phylogenetic status of Paxillosida. This group lacks an anus and suckers on the tube feet in adults and does not develop the brachiolaria stage in early development. Two controversial hypotheses have been proposed for the phylogenetic status of Paxillosida, i.e., Paxillosida is primitive or rather specialized in asteroids. In this study, we determined the complete mitochondrial DNA nucleotide sequences from two paxillosidans (Astropecten polyacanthus and Luidia quinaria) and one forcipulatidan (Asterias amurensis). The mitochondrial genomes of the three asteroids were identical with respect to gene order and transcription direction, and were identical to the previously reported mitochondrial genomes of Asterina pectinifera (Valvatida) and Pisaster ochraceus (Forcipulatida) in this respect. Therefore, the comparison of genome structures was uninformative for the purposes of asteroid phylogeny. However, molecular phylogenetic analyses based on the amino acid sequences and the nucleotide sequences from the five asteroids supported the monophyly of the clade that included the two paxillosidans and Asterina. This suggests that the paxillosidan characters are secondarily derived ones.

Close Relationship between Asterina and Solasteridae (Asteroidea) Supported by Both Nuclear and Mitochondrial Gene Molecular Phylogenies
Zoological science, 2004Co-Authors: Mioko Matsubara, Miéko Komatsu, Hiroshi WadaAbstract:Phylogenetic relationships among asteroids remain to be extremely controversial in spite of many morphological and molecular studies have been applied to this issue. In the present study, especially focusing on resolving the relationship of Asterina and Solasteridae, we reconstructed the molecular phylogenetic tree of asteroids using nuclear 18S rDNA. A close relationship between Asterina and Solasteridae, which has been suggested from analyses of mitochondrial 12S rDNA and 16S rDNA, is supported here by the nuclear 18S rDNA dataset. The support is even stronger when the sequences of mitochondrial rDNAs and nuclear 18S rDNA are combined as a total dataset. The independent support from both nuclear 18S rDNA and mitochondrial rDNAs strongly argues for a close relationship between the Asterina and Solasteridae.
