Figure 2: Phylogenetic tree of SNAP from 22 plants species.

All SNAP proteins identified in six model plants; C. reinhardtii (algae), P. patens (moss), S. moellendorfii (lycophyte), Amborella (basal angiosperm), O. sativa (monocot), and A. thaliana (eudicot), in addition to G. max (soybean), were included in the phylogenetic analysis. However, only the SNAP proteins most similar to soybean GmSNAP18, were included from the rest of the other species. The phylogenetic tree was generated using MEGA4 software package and the ClustalW algorithm, and calculated using the neighbor-joining method. The tree bootstrap values are indicated at the nodes (n = 1000).
