Cell cycle progression and cyclin levels differ in yeast and hyphae. G1-phase yeast daughter cells were synchronized by elutriation and then released into yeast (30°C) or hyphal (37°C, 5% serum) growth conditions. Cell morphology and levels of G1 cyclin Ccn1p, and B-cyclins Clb2p and Clb4p were followed using epitope tagged proteins. Ccn1p levels persisted longer and B-cyclins appeared later in hyphae, relative to yeast. Adapted from Bensen et al. 2005.
