In budding yeast, growth at the neck region connecting the mother and daughter cell is prevented by a septin ring inside the cell membrane and a chitin ring in the cell wall. Cabib and Arroyo describe recent work supporting the hypothesis that the attachment of the chitin ring to β-1,3-glucan is crucial for the control of morphogenesis at the neck.
