Virulence assay comparing C4Δcga1 mutant to the wild-type line C4 from which it was derived^a

Strain and leaf	Avg lesion area ± SE (mm2) after infection with:
	Mycelia	Spores
WT C4
1	19 ± 3.1	19 ± 0.9
2	14 ± 2.4	17 ± 1.3
C4Δcga1 mutant
1	4.5 ± 1.3	6 ± 0.8
2	4.2 ± 1.4	3.6 ± 0.8

^aMycelial inocula or conidial suspensions of the mutant or the wild type (WT) were used to infect the upper third of the first (1) and second (2) leaves. Values represent an average for at least seven leaves.
