Definition

  • according to Hottinger (2006):

PORE PLUG is an organic structure plugging a pore funnel. It is produced by the coalescence of the organic cell envelope and the organic median layer over the pore lumen. May be partially calcified by minutely perforated platelets called abaxialpore sieve plates.
