UvMsn2 is essential for pathogenicity of Ustilaginoidea virens. a Conidial suspensions collected from the wild-type HWD-2, ΔUvmsn2 and ΔUvmsn2/UvMSN2 strains were inoculated into rice panicles and photographed at 28 dpi. The number of false smut balls on each panicle was counted and analyzed. b Seeds of rice cultivar were incubated on filter papers soaked with blank control (liquid YT medium) or filtrates of 5-day-old YT cultures of the indicated strains. Shoot length was examined after incubation at 25 °C for 5 days. c Statistical analysis of the shoot length of the indicated strains. The mean values ± SD were calculated from three independent experiments, and asterisk indicates a statistically significant difference from the wild type (P < 0.01). d RT-qPCR analyses of the expression of ustilaginoidin biosynthetic genes in the indicated strains. The mean values ± SD were calculated from three independent experiments, and asterisk indicates a statistically significant difference from the wild-type strain (P < 0.01)
