Previous work has shown that, in cla4Δ cells of budding yeast, where septin ring organization is compromised, the chitin ring at the mother-daughter neck becomes essential for prevention of neck widening and for cytokinesis. Here, we show that it is not the chitin ring per se, but its linkage to β(1-3)glucan that is required for control of neck growth. When in a cla4Δ background, crh1Δ crh2Δ mutants, in which the chitin ring is not connected to β(1-3)glucan, grew very slowly and showed wide and… CONTINUE READING
