| Notes | Updated according the latest AFTOL data (Padamsee et al. 2012, Fungal Genetics and Biology 49:217-226. The earlier papers on the subject becomes supplemental. 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. Wallemia sebi possesses septal pores with and without septal pore caps. In order to differentiate this, Wallemia sebi1 and Wallemia sebi2 has been designated. Kindly refer the other Wallemia sebi too for complete data. |
