They were able to successfully predict new, previously unknown metabolic pathways. The work is published June 18 in the journal\u00a0<a style=\"color: #000000;\" href=\"http:\/\/dx.doi.org\/10.1038\/s42003-019-0440-4\"><em>Communications Biology<\/em><\/a>.<\/span><\/div>\n<div><span style=\"color: #000000;\">\u00a0<\/span><\/div>\n<div><span style=\"color: #000000;\">David Toubiana, a research specialist working with Professor Eduardo Blumwald at the UC Davis Department of Plant Sciences, began by collecting existing, known metabolic pathways from public databases. He also constructed \u201ccorrelation-based networks\u201d of metabolites \u2013 biochemicals known to be present in a line of specially-bred tomato plants. These networks link similar molecules, without saying anything about actual pathways between them.<\/span><\/div>\n<div><span style=\"color: #000000;\">\u00a0<\/span><\/div>\n<div><span style=\"color: #000000;\">Toubiana and colleagues mapped the known pathways on to the correlation networks to create a set of partial metabolic networks. They used these networks to train machine-learning algorithms to identify new pathways. In machine learning, a computer system \u201clearns\u201d a new skill without being explicitly programmed for it.<\/span><\/div>\n<div><span style=\"color: #000000;\">\u00a0<\/span><\/div>\n<div><span style=\"color: #000000;\"><strong>Four new pathways identified<\/p>\n<p><\/strong><\/span><\/div>\n<div><span style=\"color: #000000;\">Based on this training and raw data from analyzing all the biochemicals in tomato fruit, the machine was able to identify four entirely new pathways in tomato. They were: beta-alanine degradation-I, tryptophan-degradation-VII-via-indole-3-pyruvate (previously unknown in plants), beta-alanine biosynthesis-III, and melibiose degradation. The existence of the melibiose degradation pathway was confirmed in wet lab experiments.<\/span><\/div>\n<div><span style=\"color: #000000;\">\u00a0<\/span><\/div>\n<div><span style=\"color: #000000;\">The combination of correlation network analysis and machine learning is a powerful new tool for discovering metabolic pathways and networks, even when there is incomplete knowledge of all the genes and molecules involved, the researchers predict.<\/span><\/div>\n<div><span style=\"color: #000000;\">\u00a0<\/span><\/div>\n<div><span style=\"color: #000000;\">Additional authors on the study are: Rami Puzis, Lingling Wen, Noga Sikron, Assylay Kurmanbayeva, Aigerim Soltabayeva, Aaron Fait, Moshe Sagi and Yuval Elovici, Ben-Gurion University of the Negev, Israel; and Nir Sade and Maria del Mar Rubio Wilhelmi, UC Davis Department of Plant Sciences.
