  1. Target numbers were calculated using the CT values and the corresponding calibration curves. Data highlighted in bold font, indicate data outside the linear range. Data represent 2 ligation replicates (n = 2), each with 4 qPCR replicates (n = 4). Nd: not detectable. E.c.c.:Erwinia carotovora carotovora
