Figure 2From: Different evolutionary histories of two cation/proton exchanger gene families in plantsPhylogeny of the NHX family that indicates multiple independent duplication events throughout its evolutionary history. The reconciled NHX tree obtained using NOTUNG v2.6, has a duplication/loss score of 60.5 and shows 27 independent gene duplication and 40 gene loss (not shown) events.Back to article page
