Septum / Pore Cap
 |
Three-dimensional reconstruction of the septal pore apparatus of Wallemia sebi and two electron micrographs showing the adseptal extensions around the septal pore. AP, adseptal finger-like processes; Dm, electron-dense material; Edr, electron dense region; ER, endoplasmic reticulum; M, membrane; P, septal pore; se, septal pore swelling. |
Cell type: (XN) mycelium of unknown nuclear status
Component: Hypha excluding ascogenous hypha/ascus

| Notes | Septal pore ultrastructure of Wallemia sebi according to Terracina (1974), Can J. Bot 52: 2587-2590: Thick lamellate biconvex nonmembranous pore occlusion; electron-dense band within pore; folded endoplasmic reticulum associated with pore. Moore(1986) interprets the endoplasmic reticulum as a septal pore cap with saccules. This data is now replaced by AFTOL data (Padamsee et al., 2012, Fungal Genetics and Biology 49: 21-226. |
