Medicago-Sinorhizobium
Confocal image showing early nodule development in Medicago
truncatula roots at 2 days post-inoculation with Sinorhizobium
melitoi.
The bacterial cells (green) are bound to the epidermal surface of the
roots (blue), which are undergoing deformation showing branching and
curling. Courtesy of Janine Haynes, University of Delaware, USA.

Laccaria bicolor. Courtesy of Pascale Frey-Klett, INRA-Nancy, France.
Puccinia–Berberis
Aecidia of Puccinia graminis (wheat stem rust) on leaves of its alternate
host, Barberry (Berberis sp.) (magnification 40X), Amance Arboretum,
Champenoux, France. Courtesy of Pascal Frey, INRA-Nancy, France.
Lotus–Glomus
Roots of Lotus japonicus cv. Gifu colonized by the arbuscular mycorrhizal
fungus Glomus intraradices. 7 µm cross sections were stained
with Acridine Orange. RNA in intraradical fungal structures (hyphae,
arbuscules and vesicles), the phloem and the outer root cell layers
stains orange; autofluorescence (cell walls of xylem, endodermis, and
walls of fungal vesicles) appears yellow.

vulgaris) (magnification 7X). Rougimont, Vosges Mountains, France.
