Phylogenetic analysis of the relationships among chitinases from different bacteria.
The phylogenetic tree was constructed using the neighbor-joining method (MEGA6.0). All chitinase sequences were obtained from GeneBank and PDB (http://www.rcsb.org/pdb/home/home.do) and the accession numbers of chitinase were listed in the form of “AAM48520”, except for pachi. These chitinases were reported to infect multiple phytopathogenic organisms such as fungi, insects and nematodes.
