Hda1 and Hda2, are not redundant with Hos2 in the control of dimorphism and virulence.

<p>(A) Quantification of infection symptoms caused by the indicated strains on maize plants 14 dpi. Mean values of three independent experiments are shown. Total number of infected plants are indicated above each column. Statistically significant differences are indicated with asterisks (Mann-Whitney test; the number of asterisks are used for the following <i>p</i>-values: * for p<0.05, ** for p<0.01, *** for p<0.001 and **** for p<0.0001. Asterisks placed above each column and bellow the total number of infected plants correspond to comparisons with the SG200 wild-type strain. (B) Representative image of tumours induced by wild-type and <i>hos2</i> mutant strains 14 dpi. Scale bar = 1 cm. (C) Filamentation on PD charcoal plates of the indicated strains after 48 hours incubation at 25°C.
