The GSL metabolic pathway of I. indigotica. Numbers in brackets represent the numbers of genes homologous with Arabidopsis; Red, green and blue words or squares represent aliphatic, aromatic and indole GSL metabolism-related genes or products, respectively; Dashed lines indicate the predicted reaction or multiple-step reactions; BCAT: branched-chain amino acid aminotransferase; MAM: methylthioalkylmalate synthase; IPMI: isopropylmalate isomerase; IPMDH: isopropylmalate dehydrogenase; CYP: cytochrome P450 monooxygenase; GST: glutathione S-transferase; SUR: S-alkyl-thiohydroximate lyase; UGT: uridine 5′-diphospho-glucuronosyltransferase; ST: sulphotransferase; FMO: flavin-containing monooxygenase; AOP: alkenyl hydroxyalkyl producing; IGMT: indole glucosinolate O-methyltransferase; TGG: thioglucoside glucohydrolase; PEN2: penetration-resistance gene 2; BGLU: beta glucosidase; APS: adenosine 5′-phosphosulphate; APS: adenosine 5′-phosphosulphate; APK: APS kinase; GSH: glutathione; PAPS: 3′-phospho-adenosine-5′-phosphosulphate; PAP: 3′-phospho-adenosine 5′-phosphate
