  • K+-responsive groups of functionally related genes were identified by iGA based on RP lists of root genes sorted for down-regulation over six experiments (6 h K+ resupply, three replicates with two controls each). Significantly affected gene groups up to a FDR of 10% are shown. For rank and evidence details, see footnote of Table IV.
