FIG. 1.

LPS profiles and colonization of the roots of Zea mays by the parental H. seropedicae strain SmR1 and ampG mutant MHS05. (A) Sodium deoxycholate-PAGE electrophoresis patterns of LPS isolated from the parental strain (lane 1) and the mutant derivative (lane 2) grown in NFbHPN-malate medium. (B) Colonization of Z. mays roots. Results are shown as the average numbers of bacteria·g−1 fresh root ± standard deviations. The values above the columns represent the difference in colonization between parental and mutant strains. Asterisks indicate statistically (Student t test) significant differences between the parental strain and the ampG mutant in colonization of maize roots. *, P < 0.005; **, P < 0.01.
