Beyond the bacterium: planctomycetes challenge our concepts of …
2011年5月16日 · It has been proposed that planctomycetes should be included in new coarse-level bacterial clades, such as Negibacteria (which encompass Gram-negative bacteria) or Gracilicutes (which include...
Determining the bacterial cell biology of Planctomycetes - PMC
Several unusual features have been reported for bacteria of the phylum Planctomycetes, such as cytosolic compartmentalization and an endocytosis-like process. Here, Boedeker et al. provide evidence supporting a Gram-negative cell plan and the absence of endocytosis-like processes in these organisms.
The Planctomycetia: an overview of the currently largest class …
2022年1月17日 · The phylum Planctomycetes comprises bacteria with uncommon features among prokaryotes, such as cell division by budding, absence of the bacterial tubulin-homolog cell division protein FtsZ and complex cell plans with invaginations of the cytoplasmic membrane.

In the cladogram below, yellow=pseudopeptidoglycan monoderms (Gram variable), red=thick peptidoglycan monoderms (Gram positive), blue=thin peptidoglycan diderms (Gram negative), green=atypical, see note in parentheses).
The Phylum Planctomycetes - SpringerLink
2014年10月19日 · The Planctomycetes is a bacterial phylum with multiple distinctive, and often unique, morphological, structural, metabolic, and genomic characteristics. Historically, microscopic observation of the rosette-forming Planctomycetes was reported as early as 1924 when Geimsei observed peculiar rosette formations in freshwater ponds in Budapest ...
Planctomycetes - an overview | ScienceDirect Topics
In Wadden Sea sediments, Planctomycetes can account for up to 7% of the bacterial community on individual sand grains, while they form on average 5.7% of the bacterial community. On marine macroscopic detrital aggregates known as marine snow 22% of the bacteria can be Planctomycetes.
History, Classification and Cultivation of the Planctomycetes
2013年1月1日 · Here we trace the history of the planctomycetes from their initial discovery as planktonic microcolonies in lake water, to their recognition as an evolutionarily diverse phylum encompassing three classes with a vast array of unique and unusual features.
Cultivation and functional characterization of 79 planctomycetes ...
2019年11月18日 · Planctomycetes have been shown to be phylogenetically distinct and to cluster together with the biotechnologically and medically important phyla Verrucomicrobia and Chlamydiae within the PVC...
On the maverick Planctomycetes | FEMS Microbiology Reviews
2018年7月24日 · Surprisingly, Planctomycetes were found to possess a peptidoglycan cell wall and to comprise a cell plan comparable to other Gram-negative bacteria as the nucleus-like structure is rather an invagination of the cytoplasmic membrane than a cohesive compartment.
Planctomycetes: Cell Structure, Origins and Biology
Planctomycetes, and their relatives within the PVC superphylum of domain Bacteria, including verrucomicrobia and chlamydia, challenge our classical concept of the bacterium and its modes of life and provide new experimental models for exploring evolutionary cell biology and the full diversity of how living cells can be organized internally.
