[3] According to the International Code of Nomenclature of Prokaryotes (ICNP), the name Caryophanacaeae has higher priority than Planococcaceae because of its earlier publication.

[1] Analyses of genome sequences from Caryophanaceae species identified 13 conserved signature indels (CSIs) that are uniquely present in this family in the proteins phenylalanine–tRNA ligase subunit alpha, chaperonin GroEL, ribosome maturation factor RimP, BrxA/BrxB family bacilliredoxin, RNA methyltransferase, Rhomboid family intramembrane serine protease, ATP-dependent Clp protease ATP-binding subunit, DNA-directed RNA polymerase subunit beta, chorismate synthase, stage IV sporulation protein A, peptidase, KinB-signaling pathway activation protein, and DUF423 domain-containing protein.

[1] These CSIs serve as a reliable molecular means of demarcating members Caryophanaceae from other families within the order Caryophanales and other bacteria.

[2] In addition to the nomenclature anomaly, Caryophanaceae also encompassed over 100 species that had varying morphology/biochemical characteristics, demonstrating that they were phylogenetically unrelated.

[4] The original assignment of species into the family Caryophanaceae was largely based on 16S rRNA genome sequence analyses, which is known to have low discriminatory power and the results of which changes depends on the algorithm and organism information used.
