Term Information

Accession: PO:0005039
Name: primary thickening meristem
Ontology: plant_anatomy
Synonyms: PTM (exact), collar meristem (exact), meristema de engrosamiento primario (Spanish, exact), 一次肥厚（膜）分裂組織 (Japanese, exact), meristematic cap (related)
Alternate IDs: None
Definition: A shoot lateral meristem (PO:0006344) that is part of a shoot axis (PO:0025029) and has a parts multiple layers of meristematic cells (PO:0004010) located near the shoot apical meristem (PO:0020148). Source: JSTOR:4354165, ISBN:0471245208
Comment: Contributes to primary thickening of a shoot axis (PO:0025029), adventitious (shoot-borne) root (PO:0000042) formation, and formation of linkages between shot axis (PO:0000039), leaf (PO:0000036), and root (PO:0003011) vascular systems. Contiguous with the shoot apical meristem (PO:0020148) in some species, but not all. Produces more or less distinct vascular bundles (PO:0005020) surrounded by ground tissue (PO:0025059), as opposed to the more or less continuous xylem (PO:0005352) and phloem (PO:0005417) produced by a vascular cambium (PO:0005598). A primary thickening meristem is a multi-layered structure, compared to the single layer of a cambium. Found in many monocotyledons.
