SummaryEdit

Description
Čeština: Moneses uniflora, má jako i další zástupci z podčeledi hruštičkovitých-Pyroloideae semena mikroskopických rozměrů téměř bez zásobních lítek. Pro to musí být alespoň ze začátku života vyživovány jinak-parazitují na houbě, která je nedobrovolně živí. Tomuto jevu se říká mykoheterotrofie. Obrázek pořízen florescenčním mikroskopem. Objekt nabarven propidiumiodidem a fluorescíndiacetátem, excitace modrým světlem.
Français : Moneses uniflora (comme d'autres représentants de la sous-famille des Pyroloideae) produit des graines en forme de poire, microscopiques et presque sans stock énergétique. Pour cela, au moins dès le début de la vie, la plantule qui émerge de l'embryon végétal doit se nourrir différemment - elle le fait en parasitant d'autres espèces vivantes via un champignon symbiote (mycohétérotrophie). Image prise au microscope à fluorescence. Objet coloré avec de l'iodure de propidium et du diacétate de fluorescéine, excité avec de la lumière bleue
English: Moneses uniflora, as well as other representatives of the subfamily of the pear-shaped Pyroloideae, the seeds of microscopic dimensions are almost free of stockpiles. For this, at least from the beginning of life, they have to be nourished differently - they parasite on a sponge that is involuntarily alive. This phenomenon is called mycoheterotrophy. Image taken by florescence microscope. Object stained with propidium iodide and fluorescein diacetate, excitation with blue light
