Ciliary Secretion: Switching the Cellular Antenna to 'Transmit'

Cilia are microtubule/membrane-based protrusions that mediate cell motility or transduce sensory information. New work in Chlamydomonas demonstrates that cilia can also act as secretory organelles by budding enzyme-containing vesicles from the flagellar membrane for post-mitotic hatching of daughters from the mother cell wall.
