  1. a The number of transgenic plants regenerated from hygromycin selection culture
  2. b The number of transgenic plants resistant to Xoo strain PXO86. To test resistance, five to ten of the uppermost fully expanded leaves of each transgenic plant were inoculated using the leaf tip-clipping method at the booting stage. The plants were scored as resistant or susceptible based on the average lesion length at two weeks after inoculation
