Metaplanococcus is a genus of gram-positive or gram-variable, cocci or short rod-shaped bacteria in the family Caryophanaceae from the order Caryophanales. [1] The type species of this genus is Metaplanococcus flavidus. [2] [3]
Members of Metaplanococcus are previously species belonging to Planococcus. Instead of branching with species from Planococcus, this species and an unnamed Planomicrobium species formed a monophyletic branch in various phylogenetic trees constructed based on conserved genome sequences, indicating their phylogenetic relatedness. [1] The family Caryophanaceae encompassed many branching anomalies such as this one, partially due to the reliance on 16S rRNA sequences as a method for classification, which is known to have low resolution power and give differing results depending on the algorithm used. [4] In 2020, a comparative genomic study emended the family, resulting in the establishment of three new genera, including Metaplanococcus. [1]
The name Metaplanococcus is derived from the Greek adjective meta, translating into "besides" and the Latin term Planococcus, referring the genus name. Together, Metaplanococcus can be translated as a genus besides Planococcus. [1]

Members of this genus motile by means of a single polar flagellum.
17 conserved signature indels (CSIs) were identified through genomic analyses as uniquely present in this genus in the following proteins: ABC transporter substrate-binding protein, methionine–tRNA ligase, MetQ/NlpA family ABC transporter substrate-binding protein, ABC transporter permease, spore protease YyaC, N-acetyl-alpha-D-glucosaminyl-5′L-malate synthase BshA, orotidine-5-phosphate decarboxylase, and phospho-N-acetylmuramoyl-pentapeptide-transferase. [1] These CSIs provide a reliable molecular means for distinguishing members of Metaplanococcus from other genera in the family Caryophanaceae and all other bacteria.
Metaplanococcus, as of 2021, contains one species with a validly published name. [2] This genus was identified as a monophyletic clade and phylogenetically unrelated to other species in the family Caryophanaceae in studies examining the taxonomic relationships within the family. [1]
