The Common Viridiplantae Pathway (CVP) list contains pathways that are expected to be present in all or most Viridiplantae species including algae. The CVP is a subset of the UPP. 
The CVP list can be used to:

• validate pathways that have been predicted for non-Embryophyta Viridiplantae species using Pathologic
• import pathways from MetaCyc that were NOT predicted for non-Embryophyta Viridiplantae species, likely due to genome or proteome annotation problems
