Fig. 4From: Diurnal Changes in Transcript and Metabolite Levels during the Iron Deficiency Response of RicePrincipal component analyses of root metabolite profiles from Fe-sufficient and Fe-deficient rice roots. Metabolite profiles from Fe-sufficient (+Fe: green) and Fe-deficient (−Fe: red) rice roots were compared using 95% confidence regions within the collection times a 6:00–8:00, b 11:00–13:00, c 18:00–20:00 and d 22:00–24:00Back to article page
