Phenotypes of the cap1 mutant in growth, conidiation, and plant infection.

aGrowth rate and conidiation were measured on complete medium (CM). Mean and standard deviation were calculated with results from three replicates.bAppressorium formation is expressed as the percentage of germ tubes producing appressorium.cLesion formation was examined on infected rice leaves 7 days post-inoculation.Means and SD values were calculated from at least three independent experiments.dAppressorium penetration was assayed on onion epidermis at 48 h after inoculation.*The same letter indicated there was no significant difference. Different letters were used to mark statistically significant differences (P = 0.05).
