FIG. 3.

Morphologies of Myxococcus xanthus DK1622 and deletion mutant fruiting bodies on TPM agar (LS2500, ΔMXAN_3852; LS2501, ΔMXAN_5522; LS2502, ΔMXAN_4569). Cells were grown in liquid CYE to approximately 5 × 10⁸ cells ml⁻¹ and concentrated to 8 × 10⁹ cells ml⁻¹ in CYE. For analysis of aggregation, 10 μl was spotted on TPM agar and incubated at 32°C. Pictures were taken at indicated times. Bar, 1 mm.
