FIG. 1.

Cluster dendrogram of DAPG-producing Pseudomonas strains, isolated from different crops and soils worldwide, based on RAPD analyses with two 10-mer primers. The pairwise coefficients of similarity (Dice) were clustered with the UPGMA algorithm of the NTSYS numerical taxonomy and multivariate analysis system (41). Characteristics of the strains can be found in Table 1. P. fluorescens strains 2-79RN₁₀ and Q69c-80 do not produce DAPG and were included as controls.
