FIG. 5.

Sporulation of S. coelicolor K113 aerial hyphae. Aerial hyphae of S. coelicolor K113 were grown on cellophane-covered coverslips for 36 h and transferred to imaging chambers. The mosaic image is composed of images taken at 30-min intervals while Movie S5 in the supplemental material is composed of images taken at 15-min intervals. The horizontal white bar represents 10 μm. White arrows show appearance of regular invaginations in the hyphal wall, characteristic of a forming spore chain. Black arrows show germinating spores.
