Term Information

Accession: PO:0025352
Name: tubercle
Ontology: plant_anatomy
Synonyms: podaria (exact, plural), podarium (exact), 小塊茎、塊根 (Japanese, exact)
Alternate IDs: None
Definition: An enlarged leaf base (PO:0020040) that is fused with adjacent shoot axis (PO:0025029) tissue. Source: ISBN:9780881928501, JSTOR:3093870
Comment: Found in cacti and other succulents. The upper part of a leaf from which a tubercle develops is usually shed early in development. Tubercles are often conical, but they may merge with those directly above and below to form ribs, as in saguaro (Carnegiea), or they may elongate, as in species of pincushion cacti (Mammillaria). In species with tubercles, the areole bud (PO:0025353) is often found at the distal end of the tubercle. The areole bud originates in the leaf axil (PO:0009023) of the leaf that becomes the tubercle, but is displaced to the tip through elongation of the tubercle.
