Consolidating cyanobacterial systematics through harmonization of polyphasic and genomic taxonomy

Principle investigator: Jan Mareš (HBÚ BC)
Co-investigator from the department: Jeffrey R. Johansen
Funding provider: the Grant Agency of the Czech Republic
Grant No.: 22-06374S
Duration: 2022- 2024

Since 2000, criteria for recognition of cyanobacterial taxa utilizing the polyphasic approach have
been developed. Due to the slow pace of phylum-wide revision, genome taxonomy approaches
have been introduced to avoid a taxonomic bottleneck in metagenomic studies. Genome
taxonomy has not been integrated into the existing taxonomy, which has caused substantial
confusion between the fields. We will compare these approaches by collecting complementary
data within the model group, Synechococcales, the best studied group in terms of both
genomes assembled and recent polyphasic taxonomic effort. Direct comparison will allow us to
integrate both approaches, evaluate taxonomic boundaries, and derive taxonomic concepts for
cyanobacteria that will satisfy and be workable for all researchers.
Aims of the project:
1) To assemble a set of strains characterized by polyphasic data and whole genome sequence
2) To assess taxonomic boundaries among species, genera, families, and orders by both
approaches
3) To propose a unified concept, based in phylogenomics but compatible with existing
taxonomy and nomenclature
