Effect of snt2 disruption on developmental parameters of Fusarium oxysporum f.sp. melonis (FOM). Different letters (in parentheses) define significantly different groups.

Isolate	Radial growth rate (mm/day)*	Conidia production (×104 conidia/cm2 colony)	Biomass accumulation (mg/25 mL)
Wild‐type	7.2 ± 1.0 (a)	12.7 ± 1.7 (a)	94.6 ± 8.2 (a)
D122	4.3 ± 1.2 (b)	6.2 ± 1.2 (b)	65.7 ± 5.2 (b)
Δsnt2	3.5 ± 1.1 (b)	2.0 ± 0.7 (b)	62.8 ± 7.7 (b)
3(15)	3.4 ± 0.2 (b)	0.6 ± 0.1 (b)	58.7 ± 4.8 (b)

^* Comparative analyses of the linear growth rate and conidial production of FOM snt2 mutants [D122 and the Δsnt2 mutant, as well as an additional confirmed snt2 disruptant, 3(15)] and the wild‐type isolate were performed on cultures grown on potato dextrose agar (PDA) medium. Biomass accumulation was examined after incubation in Fusarium minimal liquid medium (FMM). Standard errors and statistical differences [(P≤ 0.05) in parentheses] were calculated on the basis of three independent experiments by the Least Significant Difference (LSD) Tukey‐Kramer multiple comparison test.
