Average intercalary lengths of wild-type F. graminearum and the HEX1 mutants that were infected with FgV1 or virus free

Mutation and infection status of strain	Intercalary lengtha (μm)
WT-VFb	38.3 a
WT-VIc	20.9 c
Δhex1-VF	32.6 b
Δhex1-VI	18.7 c
HEX1 OE-VF	37.6 a
HEX1 OE-VI	12.1 d
Δhex1::HEX1-VF	37.8 a
Δhex1::HEX1-VI	19.9 c

^aIntercalary length is equivalent to cell length. The fungi were grown on solid agar medium (PDA). Values within a column with different letters are significantly different (P < 0.05) based on the Tukey test.

^bWT-VF, virus-free F. graminearum.

^cWT-VI, F. graminearum infected with FgV1.
