42 Facts About Planctomycetota

Planctomycetota are a phylum of widely distributed bacteria, occurring in both aquatic and terrestrial habitats.

Many Planctomycetota occur in relatively high abundance as biofilms, often associating with other organisms such as macroalgae and marine sponges.

Planctomycetota are included in the PVC superphylum along with Verrucomicrobiota, Chlamydiota, Lentisphaerota, Kiritimatiellaeota, and Candidatus Omnitrophica.

The phylum Planctomycetota is composed of the classes Planctomycetia and Phycisphaerae.

Early examination of members of the Planctomycetota suggested a cell plan differing considerably from other bacteria, although they are now confirmed as Gram-negative bacteria, but with many unique characteristics.

Bacteria in the Planctomycetota are often small, spherical cells, but a large amount of morphological variation is seen.

Interest is growing in the Planctomycetota regarding biotechnology and human applications, mainly as a source of bioactive molecules.

Many Planctomycetota have a holdfast, or stalk, which attaches the cell to a surface or substrate.

Early examination of the Planctomycetota suggested that their cell plan differed considerably from both Gram-positive and Gram-negative bacteria.

Until recently, bacteria in the Planctomycetota were thought to lack peptidoglycans in their cell walls, and were instead suggested to have proteinaceous cell walls.

Planctomycetota were once thought to display distinct compartmentalization within the cytosol.

In marine environments, Planctomycetota are often suspended in the water column or present as biofilms on the surface of macroalgae, and are often exposed to harmful ultraviolet radiation.

Bacteria in the Planctomycetota that are anammox-capable form the order Brocadiales.

Planctomycetota often perform a lifestyle switch between both a sessile stalked stage and a free-swimming stage.

Planctomycetota is one of the only known phyla whose members lack FtsZ proteins.

The species Kolteria novifilia forms a distinct clade of Planctomycetota, and is the only known species to divide by lateral budding at the middle of the cell.

Planctomycetota are known for their unusual cellular characteristics, and their distinctness from all other bacteria is additionally supported by the shared presence of two conserved signature indels .

Planctomycetota contain an important conserved signature protein that has been characterized to play an important housekeeping function that is exclusive to members belonging to the PVC superphylum.

When comparing under a microscope, a defining characteristic for some Planctomycetota is that a single unlinked rRNA operon can be identified near the origin.

Some Planctomycetota thrive in regions containing highly concentrated nitrate, and have genes that are required for heterotactic acid fermentation.

Planctomycetota were originally believed to exist exclusively in aquatic environments, but they are noe known to be abundant in soils and hypersaline environments.

Some Planctomycetota were found in the digestive systems of marine lifeforms, while others tend to live among eukaryotes.

Planctomycetota have a significant impact on global biogeochemistry and climate, with their ability to mineralize and break down detritus particles in the water column.

Many Planctomycetota have the ability to breakdown extremely complex carbohydrates, making these nutrients available to other organisms.

Some Planctomycetota are suggested to be capable of breaking down carrageenan.

Planctomycetota have often been observed in association with many organisms, including, macroalgae, microalgae, marine sponges, and plants such as lichens and bryophytes.

Planctomycetota are often associated with marine surfaces high in nutrients.

Almost 150 Planctomycetota species have been isolated from the bio?lms of macroalgae, and these communities associated with macroalgae are mainly independent of changes in geographical distribution.

The seaweed Caulerpa taxifolia was incubated under higher CO2 conditions, and the abundance of Planctomycetota increased substantially, as much as 10 times in some species.

Planctomycetota species are often associated with the surfaces of marine sponges.

The symbiotic relationship among sponges and Planctomycetota contributes to the health of the sponge, and the sponge often provides suitable habitat and nutrients to the Planctomycetota.

Planctomycetota were found to be highly abundant in lichen communities throughout northwestern Siberia and displayed extremely high diversity.

Planctomycetota have been associated with lichen communities and Sphagnum wetlands.

The growth of many Planctomycetota is often supported by the essential nutrients provided by other bacteria within the community, and some Planctomycetota rely strongly on symbiotic relationships with other bacteria.

Yet it has been demonstrated that the Planctomycetota can survive on high-molecular-weight polysaccharides as their only source of carbon, meaningthey must have the ability to incorporate complex carbon substrates into their cytoplasm.

Second, the complex substrates become anchored to the outside of Planctomycetota, which are then able to slowly break down these substrates into oligosaccharides, which are able to be transported into the periplasm of Planctomycetota by specialized proteins.

Planctomycetota are unique in that they have large invaginations of their cytoplasmic membrane, pulling away from the peptidoglycan cell wall and leaving room for the periplasm.

Planctomycetota are the most dominant phylum of bacteria capable of performing anammox, thus the Planctomycetota capable of performing anammox play an important role in the global cycling of nitrogen.

Sterol synthesis is suggested to be associated with regulation of membrane fluidity in Planctomycetota, and has been described as essential to the proper growth and reproduction of G obscuriglobus.

Recently, interest has arisen in examining the Planctomycetota regarding their potential roles in biotechnology, mainly as a source of bioactive molecules, of interest mainly to the pharmaceutical industry.

Planctomycetota species are worthwhile considerations in challenging the current models for the origin of the nucleus, along with other aspects of origin and evolution of the eukaryotic endomembrane system.

Planctomycetota species were recently identified as being an opportunistic human pathogen, but a lack of culture media limits studies on the bacteria in the Planctomycetota as pathogens of humans.
