To maintain ploidy, unidirectional progression through the phases of the cell cycle (G1 → S → G2 → M → G1) is essential. To keep cells from regressing, the transitions of the mitotic cell ...

Therefore, their cell cycles, which lack G1 and G2 phases and checkpoints, are totally controlled by the cytoplasm. The simplest cell cycle reveals the essential minimum of cell-cycle control.

This sequential expression followed the phases of the traditional cell cycle: G0/G1 (the cell grows larger), S (the cell replicates its DNA), and G2/M (the cell prepares for division and then splits).

New research from an international team of plant biologists, led by researchers at the VIB-UGent Center for Plant Systems Biology, has revealed crucial insights into the role ...
