Phylogenetic tree of Arachis duranensis and Arachis ipaensis aquaporins along with Arabidopsis thaliana and Glycine max. The analysis grouped aquaporins into five different clusters. The genes from A. duranensis, A. ipaensis, A. thaliana and G.max are preceded by the prefixes Adu, Aip, At, and Gm, respectively. The number next the branches represents bootstrap values ≥50% based on 1000 resamplings
