A cell shape in which an organism is flat and circular.

Disc-shape anisotropic cell-wall growth

DOI-backed graph linking anisotropic, planar peptidoglycan or S-layer growth and suppressed axial extension to flat disc-shaped cell geometry.

Disc-shape anisotropic cell-wall growth Interactive directed graph showing evidence-backed causal relationships for disc shaped.

Edge evidence

  • planar envelope growth causes flat disc geometry biolink:causes

    Planar envelope growth produces a 2D-expanded cell body.

    • DOI:10.1099/ijs.0.65431-0 flat square or disc-shaped cells Supports planar envelope growth producing flat morphology in disc-shaped halophiles.
  • axial extension suppression contributes to flat disc geometry RO:0002326

    Suppression of axial extension keeps cells thin.

    • DOI:10.1146/annurev-cellbio-101011-155745 cell shape is genetically determined Supports anisotropic growth as a control mechanism for cell shape.
  • flat disc geometry manifests as disc shaped METPO:2007400

    Flat geometry manifests the disc-shaped trait.

    • DOI:10.1099/ijs.0.65431-0 disc-shaped cells Supports the trait endpoint.
  • S-layer glycoprotein C-terminal processing and lipid anchoring enables flat disc geometry RO:0002327

    C-terminal processing and lipid anchoring of the S-layer glycoprotein is required for stable flat plate-shaped cell formation.

    • DOI:10.1099/mic.0.001012 Required for the C-terminal processing and covalent lipid attachment of S-layer glycoprotein, required for effective and stable plate-shaped cell formation.
  • disc shaped interconverts with rod-shaped morphology

    Disc/plate cell type interconverts with the rod cell type as part of regulated shape switching.

    • DOI:10.1038/nature13983 H. volcanii exhibits interconvertible plate and rod cell types; transition from a disk-shape to a rod-shape.
