^aPercentage referred to the number of shoots displaying symptoms of desiccation on the total number of shoots (approximately 25–30 per plant).

^bSamples consisted of leaves taken from the shoots harbouring the inoculation points; the leaves were collected 25–30 cm above the inoculation points.

^cThree shoots were randomly selected to determine if the bacterium spread from the inoculated shoots to the rest of the plants.

^dSee Fig. 5.

^eTen mock-inoculated plants.
