Flagellar gliding in choanoflagellates

Year: 2025

Type: article

Abstract: ). Here, we show that choanoflagellates engage in gliding motility under mild confinement. Choanoflagellate gliding is abolished by flagellum ablation and by treatment with chemical inhibitors of intraflagellar transport (IFT), suggesting that it is mediated by flagella and requires IFT. Gliding is conserved in at least two choanoflagellate species - Choanoeca flexa and Salpingoeca rosetta. These findings expand the known motility repertoire of choanoflagellates and enrich our understanding of the evolution of cell motility.
