Summary
| Description | X 400 English: Hyphea of Hyaloperonospora parasitica (downy mildew) growing within the leaf of a compatible (susceptible) Arabidopsis thaliana (cf.wikipedia) observed by bright-field microscopy. The staining with trypan blue makes the cytoplasm of H. parasitica dark blue. The long structure is the hyphea, whereas the little spheres are haustoria. Bigger dark spheres are Oospores, the long term storage form of H. parasitica. This is the mating step of the short life cycle of H. parasitica. Français : Hyphes de Hyaloperonospora parasitica (Mildiou) dans une feuille d'Arabidopsis thaliana (cf.wikipedia) susceptible (compatible) observée au microscope optique. La coloration au bleu de trypan donne une couleur bleue foncée au cytoplasme de H. parasitica. La longue structure est l'hyphe, tandis que les petites sphères sont les haustoria. Les sphères plus grosses et très sombres sont les Oospores, la forme de stockage à long terme de H. parasitica. C'est l'étape reproductive du cycle court de H. parasitica. |
