Fig. S1. Effects of the isolates in planta. Arabidopsis Col-0 seedlings were pre-

pared on agar-solidified medium at 5 d post-germination; 2 μl of microbial sus-

pension was dropped on the opposite side of the plate at a 5 cm distance from the

root tip. Photographs were taken after 7 d of co-cultivation.

Fig. S2. Agarose gel electrophoresis showing RAPD bands of KB1, KB5, KB10 and KB11,

produced by each indicated primers. The molecular weight standard (lane M) is a 1 kb plus

DNA ladder (Nano helix. Co.). a; inoculated strain, b; re-isolated strain from leaves.
