Cabbage root infection. Coloured scanning electron micrograph (SEM) of a cross-section through one of the roots of a cabbage (Brassica sp.) infected with the parasitic slime mould Plasmodiophora brassicae (yellow spheres). This is the cause of club root. This pathogen attacks cruciferous plants and is especially damaging to brassicas (such as cabbages, cauliflowers and sprouts). The infection stimulates cell division, resulting in the characteristic clubbing of the roots. As the roots decay, resting spores are released into the soil, where they can remain viable for many years. Magnification: x510 when printed 10cm wide.
