Fig. 7

The GreenCut can be divided in ancestral, core and land specific sets. a Proteins with unknown functions (white), known functions (light grey) and predicted functions (dark grey) are depicted based on [73]. ‘Other’ refers to a domain or motif suggesting a general function but not a specific functional category. b Cellular location of A. thaliana protein families in the Ancestral and Core (essential) sets based on TargetP analysis. Mixed: members of an ortholog group show different targeting signals. c Functional categories of core and ancestral genes [73], showing that proteins involved in pigment synthesis, carbohydrate metabolism, and cofactors are all maintained in the core set and do not appear to have undergone differential losses
