Phylogenetic studies

  • Phylogenetics analysis of different group
  • f marine fungi
  • Genomic studies of marine fungus

Acremonium fuci – comparative analysis

  • f mitochondrial genome (almost done)

  • Metagenomics. White Sea
  • 993 OTUs, 44 identified to genus

level

Problems

  • Biological contamination – sequencing of all

living cells in the sample

  • Genetic contamination – it’s hard to find

universal and specific barcode for eukariots or fungi etc.

  • Data contamination – chimeric sequences
