Fig. 2From: Genome-wide investigation and expression analysis of Sodium/Calcium exchanger gene family in rice and ArabidopsisPhylogenetic relationships among Arabidopsis, rice, Brachypodium, foxtail millet, poplar and potato NCX proteins. Multiple sequence alignment of NCX proteins was done using ClustalW2 and the phylogenetic tree was generated using MEGA6 software by the Neighbor-joining method with 1000 bootstrap replicates. NCX proteins were categorized into five different clades depending upon the relative sequence homology of each member of the clades. NCX proteins from Arabidopsis, poplar, potato, rice, Brachypodium and foxtail millet are denoted by different shapes viz. circle, triangle, rectangle, solid triangle, solid circle and solid rectangle, respectivelyBack to article page
