Fig. 4From: Occurrence of plant pathogenic Pseudomonas syringae in the Danube River Basin: abundance and diversity assessmentAverage freezing temperature among ice-nucleation positive strains of Pseudomonas syringae from the Danube. INA positive strains are grouped into three types based on the average temperature of freezing (Type I < −4°C, Type II −4°C to −7°C, and Type III > −7°C)Back to article page
