Morphology and production of conidia and sclerotia by A. flavus ΔfluG strains on PDA. (A) Cultures were grown at 30°C under white light and in the dark for the specified numbers of days. Washed, conidia of the 7-day-old cultures were washed off to expose sclerotia (black aggregates). (B) Quantification of conidia and sclerotia. Gray bars, wild-type CA14; crosshatched bars, ΔfluG strains; open bars, fluG complemented strains. Conidiation and sclerotial production under light by the fluG complemented strains were not determined. The complemented strains shown are those putatively having the native fluG promoter (see Fig. S1 in the supplemental material). The numbers of conidia and sclerotia are the total count per plate. The error bars indicate standard deviations.
