From: Bioinformatic analyses to uncover genes involved in trehalose metabolism in the polyploid sugarcane
Plant trehalose metabolism. (a) Enzymes involved in trehalose synthesis and degradation. (b) The number of genes encoding trehalose-6-phosphate synthase (TPS), trehalose-6-phosphate phosphatase (TPP), and trehalase (TRE) in Arabidopsis thaliana, Oryza sativa, and Zea mays. Trehalose-6-phosphate (T6P) is a central sugar sensor in plant metabolism. Its biosynthesis occurs from UDP-glucose (UDPG) and glucose-6-phosphate (G6P) by TPS activity. Subsequently, the T6P is converted to trehalose by TPP. Trehalose is hydrolyzed into two molecules of glucose by TRE. Multigenic families encode TPS and TPP.
