Proposed diagram showing the changes in metabolic pathways along with metabolites and genes induced by P. indica after colonization. Metabolites involved in the pyruvate metabolism are altered after 7 days of P. indica colonization in Chinese cabbage root. Elevation of metabolites involved in pyruvate metabolism consequently trigger (1) fatty acid biosynthesis and (2) TCA cycle, which produces 2-oxo-glutarate and elevates GABA. P. indica-induced GABA promotes abiotic stress acclimation and impedes growth of plants; whereas, L-glutamine or glutamate that could be produced via P. indica-induced pyruvate and –activated TCA cycle negates such effect as proposed49. List of genes induced by P. indica (marked in red) from previous EST-library7 ASP: aspartate aminotransferase. GAD: glutamate decarboxylase. MDH: malate dehydrogenase. 2-OAD: 2-oxaloacetic dehydrogenase. PDH: pyruvate dehydrogenase.
