Roscovitine reduces and colchicine increases the amounts of MsRBR and phospho-MsRBR proteins in alfalfa cells exposed to double synchronization. (A) Frequency data of G1, S, and G2 cells at various time points after removal of the inhibitor [hydroxyurea (HU) at 10 mM] and treatment with roscovitine or colchicine for the indicated time periods. Characteristic DNA histograms from flow cytometry are also shown. (B) Western blot of protein extracts with anti-AtRBR1 antibody (upper) and anti-human pRb phosphopeptide antibody (low). C, control, non-synchronized culture; BW, before washing out HU; AW, after washing out HU.
