Exine Resistance to Fungal Infestations in Strelitziaceae

旅人蕉科(Strelitziaceae)花粉外壁抗阻真菌的感染

摘要


鶴望蘭屬(Strelitzia)和旅人蕉屬(Ravenala)花藥開裂後,常見花粉壁與細胞質受到真菌菌絲的感染。厚度很少超過0.1μm的花粉外壁不因此種感染而瓦解。真菌菌絲是經由花粉外壁受到原生質體滲透壓變異,或是因機械性外力的破壞所形成的裂縫進入花粉粒的細胞質中。我們並沒有找到真菌酵素或其他微生物破壞此科植物之花粉外壁的證據。

並列摘要


Fungal infestation of pollen wall and cytoplasm is common in Strelitzia and Ravenala (Strelitziaceae) after anther dehiscence. The exine, rarely more than 0.1 μm thick, is not degraded by these infestations. Fungal hyphae enter the pollen grain cytoplasm through ruptures in the exine caused by osmotically shocked protoplasm or mechanical damage. We find no evidence that fungal enzymes or other microbes breach the thin exines of this family.
