WebA recent study by Lin et al. has made an interesting attempt to connect SUMOylation to cell-cycle control in Chlamydomonas. Chlamydomonas normally performs cell enlargement during a prolonged G1 phase before undergoing multiple cell fission events in a series of rapid alternating S phases and mitoses (S/M), to produce uniform daughter cells ... WebThe Chlamydomonas cell cycle consists of a long G1 during which cells can grow >10-fold, followed by multiple rapid cycles of DNA replication and segregation. CDKA and CDKB execute nonoverlapping functions: CDKA promotes transition between G1 and entry into the division cycle, while CDKB is essential specifically for spindle formation and ...
