The Five AhMTP1 Zinc Transporters Undergo Different Evolutionary Fates towards Adaptive Evolution to Zinc Tolerance in Arabidopsis halleri
Figure 3
Phylogenetic analysis of MTP1 gene sub-family from A. thaliana, A. lyrata, and A. halleri.
(A) Maximum likelihood tree of MTP1 protein sequences from A. thaliana, A. lyrata and A. halleri. Bootstrap values are indicated in percentage (100 replicates). (B) Alignment of predicted amino acid sequences of MTP1s from A. thaliana, A. lyrata and A. halleri. Sequences are represented in 80 amino acids long blocks. The AtMTP1 protein sequence is from accession NP_850459 and the AlMTP1 one was extracted from scaffold 4 of the A. lyrata sequencing project available on http://genome.jgi-psf.org/cgi-bin/runAlignment?db=Araly1&advanced=1. Identities with AtMTP1 are represented by a dot and differences are written in alphabets. Dashes (–) signify deletions. Six transmembrane domains (TMDI to TMDVI) predicted using TMHMM server v. 2.0 [34] are shaded. The histidine rich loop is located between TMDIV and TMDV.
