FIGURE 2.
The lack of dnmA or fisA causes severe defects in sexual development. Strains TRV1 (WT), CVG1 (ΔdnmA), CVG2 (ΔfisA), and CVG3 (ΔdnmA ΔfisA) were induced to undergo sexual development as previously reported (Kawasaki et al., 2002). Intact (upper panel) or crushed Cleistothecia (middle and lower panels) from 8-day old cultures were isolated and observed under the microscope. White arrows point to ascogenous tissue (middle panel) and ascospores (lower panel).
