Fig. 1From: The Arabidopsis phytohormone crosstalk network involves a consecutive metabolic route and circular control units of transcription factors that regulate enzyme-encoding genesStructural connectivity of the enzyme-based Arabidopsis phytohormones crosstalk network (EAPCN) at the biosynthesis level. Green nodes represent eight phytohormones (abscisic acid, auxin, brassinosteroid, cytokinin, ethylene, gibberellin, jasmonic acid, and salicylic acid). The other nodes represent enzymes involved in synergistic or antagonistic crosstalk between the phytohormones. Red nodes represent enzymes for which there are experimental data (see Additional file 3, section I for details). Yellow nodes represent enzymes that are inferred to be involved in synergistic or antagonistic crosstalk. Edges represent nodes that exhibit either synergistic or antagonistic interactionsBack to article page
