Bacillota
The Bacillota (synonym Firmicutes) are a phylum of bacteria, most of which have Gram-positive cell wall structure. They have round cells, called cocci (singular coccus), or rod-like forms (bacillus). A few Bacillota, such as '' Megasphaera'', ...

An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota. The name "endospore" is suggestive of a spore or seed-like form (''endo'' means 'within'), but it is not a true spore (i.e., not ...

History
The genus ''Ureibacillus'' was split from the genus ''Bacillus
''Bacillus'', from Latin "bacillus", meaning "little staff, wand", is a genus of Gram-positive, rod-shaped bacteria, a member of the phylum ''Bacillota'', with 266 named species. The term is also used to describe the shape (rod) of other so-sh ...
'' in 2001 to encompass ''Bacillus thermosphaericus'' (now ''Ureibacillus thermosphaericus'') as well as several newly discovered similar strains of bacteria.[
In 2020, multiple ''Lysinibacillus'' species were transferred into ''Ureibacillus'' based on branching patterns in various phylogenetic trees constructed based on conserved genome sequences, indicating their phylogenetic relatedness.]Caryophanaceae
The ''Caryophanaceae'' is a family of Gram-positive bacteria. In 2020, the now defunct family ''Planococcaceae'' was merged into ''Caryophanaceae'' to rectify a nomenclature anomaly. The type genus of this family is ''Caryophanon.''
The family ' ...
'' 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.conserved signature indels
Conserved signature inserts and deletions (CSIs) in protein sequences provide an important category of molecular markers for understanding phylogenetic relationships. CSIs, brought about by rare genetic changes, provide useful phylogenetic markers ...
