Conserved binding of eIF4E 1 (CBE1) is a conserved plant-specific protein with a predicted eIF4E-binding motif. A, phylogenetic tree of predicted CBE1 proteins from representative plant species. The phylogenetic tree was generated using the http://www.phylogeny.fr/ pipeline (39) with alignment by MUSCLE and tree construction by PhyML using 500 bootstrap replicates.

B, alignment of the N-terminal eIF4E-binding motif (Y(x)₄Lφ) of selected CBE1 proteins in blue (eIF4G and eIFiso4G motifs shown for comparison in green).
