Table 3.

Populations of wild-type (WCS365 or PCL1239), complemented mutant (PCL1234), and mutant complemented with a deleted xerC (PCL1250), on potato root tips 14 days after inoculation of potato stem cuttings with a 1:1 mixture

Colonization test	Mean log₁₀(CFU + 1)/ cm of root tip
Colonization test	Wild type	Various xerC derivatives
WCS365 vs. PCL1233	4.6^a	2.9^b
	6.1^a	3.1^b
PCL1239 vs. PCL1234	4.6^a	4.6^a
	5.1^a	5.5^a
PCL1239 vs. PCL1250	5.6^a	3.8^b
	5.0^a	3.4^b
7NSK2 vs. SSS	5.3^a	1.6^b
	5.6^a	4.5^b

Statistical analysis was performed as described in Table 2.
