lax2-2	60	17.8 ± 2.8***	9.9 ± 0.9***	0.0 ± 0.0***	36.3 ± 4.0***
Wild type (Norin 8)	60	18.7 ± 4.3	9.4 ± 0.7	13.6 ± 2.2	92.5 ± 8.8
lax2-3	60	17.8 ± 3.2*	10.7 ± 0.8***	0.1 ± 0.2***	54.0 ± 4.3***

Average values ± sd are shown. Asterisks (*** and *) indicate that the differences between the mutants and their corresponding parental wild types are statistically significant at P < 0.001 and < 0.05, respectively, according to the Student's t test.
