From: Regulation of multiple tip formation by caffeine in cellular slime molds
Effect of caffeine on multiple tip formation in different Dictyostelids. A) In P. pallidum, secondary tip formation was monitored at 6 h, 9 h, 12 h and 20 h of development. B) In D. aureostipes and D. minutum, ectopic tips were observed at 2 h and 3 h, respectively after transferring the slugs in plate containing 5 mM caffeine. Arrow indicates multiple tip formation at respective time intervals in different Dictyostelids. Scale bar = 200 μm.
