Fig. 7From: Metabolic alterations provide insights into Stylosanthes roots responding to phosphorus deficiencyFlavonoid metabolism pathway in stylo roots response to P deficiency. The pathway was designed based on KEGG pathways (http://www.kegg.jp/kegg/pathway.html) as described by Zhang et al. [51] and Kc et al. [43]. The light red, blue, yellow and grey colors indicate up-regulated, down-regulated, no response and no identified metabolites in metabolome, respectively. The solid arrows show direct and dotted arrows represent indirect and speculated steps in the pathway. Important genes are marked on the metabolic procedureBack to article page
