Other claims from this paper (4)

Observation The ∆CR-4 mutant did not produce tabtoxin, unlike ∆GI-1.
Intervention effect The ∆CR-4 mutant grew to a lesser extent than the wild-type strain.
Mechanism The tabtoxin biosynthetic gene cluster in GI-1 is required for virulence but not for establishment of compatibility.
Observation The ∆CR-4 mutant caused no disease symptoms in tobacco.
