Web10 dec. 2024 · NCBI Taxonomy will append a list of 42 names of prokaryote phyla published for validation purposes as required under the International Code of Nomenclature for Prokaryotes (ICNP). You can still search for previous informal names, and any informal phylum rank names not addressed in the validation list will remain unchanged. WebTo study the relationship between the extents of LCR and gene paralogy, we analyzed a set of eight groups of prokaryotic species, four archaeal and four bacterial (Methods). For each group, we determined the orthologous relationships of proteins across genomes and estimated the levels of LCR and paralogy in each local cluster of orthologous genes …
