Assay of tumour formation by Agrobacterium tumefaciens using potato tuber discs. Potato discs were inoculated with (A) A. tumefaciens A208, (B) no bacteria, (C) OlsE-deficient mutant MAV07, (D) OlsB-deficient mutant MAV08. Potato tuber discs were scored every 3 days for tumour formation. The tuber discs have a diameter of 1 cm. Images were taken 48 days after inoculation. Tuber discs were incubated at 28°C. The arrows highlight some tumours on the potato discs.
