Root Induction by Ngrol or Rirol genes. The frequency of root production was determined by calculating the number of segments that formed roots as a percentage of the total number of segments in each flask. Binary vector pMM454-Km was used as the control. (A) Leaf segments were infected with A. tumefaciens harboring constructs of Ngrol and Rirol genes. Sixty leaf segments in ten flasks were used for each construct. Bars indicate SE (n = 10). (B) Leaf segments were inoculated with the constructs of rolB homologues. Fifty-four leaf segments in nine flasks were examined for each construct. Bars indicate SE (n = 9).
