ASAC Project 2275 data provides microscope and molecular evidence for a fungal symbiosis in the Antarctic leafy liverwort Cephaloziella exiliflora. The dataset compares fungi isolated from specimens collected in Australia and continental Antarctica with Hymenoscyphus ericae using ITS region DNA sequences. The Australian Antarctic Data Centre (AU_AADC) published this metadata record in March 1998.
Use Cases
- Compare ITS region DNA sequences of fungal isolates from Cephaloziella exiliflora with Hymenoscyphus ericae to assess sequence divergence.
- Analyze microscope evidence of hyaline, septate fungal hyphae infections in rhizoids and adjacent axial cells.
- Map the geographical distribution of Hymenoscyphus ericae by linking fungal isolates to collection locations in Australia and continental Antarctica.
- Investigate the host range extension of H. ericae by correlating fungal presence with the specific liverwort species Cephaloziella exiliflora.
- Characterize fungal morphology and infection type (mycorrhiza-like or mycothalli) based on descriptions of hyphae in rhizoids and axial cells.
Strengths
- ITS region DNA sequence divergence data quantified at less than 2.1% for isolates.
- Evidence derived from specimens collected from two distinct geographical locations: Australia and continental Antarctica.
- Dataset provides both microscope evidence and molecular evidence for the fungal symbiosis.
Limitations
- Dataset size, row count, and specific column structure are unknown.
- Data is temporally stale, with last metadata update in March 1998.
- Sample data and file formats are unavailable for direct inspection.
