Fig 10. Two transcription factors targeted by Ros1 are involved in the regulation of spore development.

Maize seedlings were inoculated with the indicated strains. Typical tumors induced by wild type and corresponding deletion strains are shown in the left panels. Tumor tissue was collected at 12 dpi, dispersed in water and spore structures were observed with a light microscope (middle panels). Enlarged parts of the middle panel are depicted in the right panel. Bar = 10 μm.
