Confocal microscopy imaging of G. cichoracearum haustoria. Haustoria installed in plant epidermal cells are visualized by staining with sulpho-rodamine B (SRB) and 1-anilinonaphthalene-8-sulfonic acid (ANS). Z-stack compilations are shown for samples isolated at different times post infection (hpi). Arrows indicate the haustorial nuclei (HN) identified by DAPI staining (Additional file 4). EHM: extra haustorial membrane; EHMx: extra haustorial matrix. Bars: 10 μm.
