Fig. 1. Frequency and phylogenetic affiliation of isolates possessing various metabolic activities in: (A) total population of 123 morphotypes, (B) NR population (rhizosphericisolates obtained on nutrient agar) of 51 morphotypes, (C) MR population (rhizospheric isolates obtained on M9 minimal medium) of 54 morphotypes, and (D) E population(root endophytes) of 18 morphotypes. The column of total isolates shows phylogenetic affiliation of each population for comparison.
