The maize cDNA sequence (ZmPRL) homologous to the Arabidopsis thaliana PROLIFERA or to the different MCM7 genes (yeast cdc47, as an example) has been identified by differential display due to its increased mRNA accumulation in the apical region of the maize immature embryo. Probably two sequences coding for ZmPRL exist in the maize genome and when comparing the different MCM protein sequences available, the protein clusters with other MCM7 proteins already described. Analysis by in situ hybridization shows that the pattern of ZmPRL mRNA accumulation is in agreement with the pattern observed for genes related to cell cycle in plants and that the expression is mostly found in the apical meristem. It is proposed that this is a consequence of the mechanisms that control the formation of the apical-basal pattern in plant embryo acting upon the regulation of the cell cycle. |
