Stepwise Evolution of Insertion Sequences in VAMP72 Proteins Across the Green Plant Lineage

Caption

A phylogenetic tree (left) illustrates the major green plant lineages, from chlorophyte algae to angiosperms. Aligned amino acid sequences (right) show the insertion regions in VAMP72 and VAMP727 homologs from representative species. The emergence of key sequence motifs—such as tyrosine-based and acidic dileucine motifs—occurred in a stepwise fashion during evolution, ultimately giving rise to VAMP727.
