Fig. 1From: Occurrence of plant pathogenic Pseudomonas syringae in the Danube River Basin: abundance and diversity assessmentSampling locations on the Danube River (D1–D12) and its tributaries (T1–T3). Pie charts associated with sampling sites show the percentage share of detected Pseudomonas syringae phylogroups in the total number of isolates from that site. The Psy population sizes are indicated next to the pie charts and estimated in CFU per L. The black arrowhead shows the direction of the river flowBack to article page
