Fig. 1From: Genome-wide identification and expression profile analysis of metal tolerance protein gene family in Eucalyptus grandis under metal stressesPhylogenetic relationship of MTP proteins family members of Eucalyptus grandis, Populus trichocarpa, Arabidopsis thaliana, and Oryza sativa. The MTP protein sequences were aligned by ClustalX 2.0.8, and the phylogenetic trees were constructed based on the analysis of bootstrap with 100 replicates by neighbor-joining method using the MEGA 6.0 program. The identified proteins were classified into three sub-families (Fe/Zn-MTPs, Mn-MTPs, and Zn-MTPs) and seven groups based on the previous reports of phylogenetic relationships. The Zn-MTP group (violet line) contains MTP1 to MTP4, MTP5, and MTP12 groups; the Mn- MTP group (blue line) contains MTP8 and MTP9 to MTP11 groups; and the Zn/Fe- MTP group (red line) contains MTP6 and MTP7 groupsBack to article page
