Sucrose Metabolism: Gateway to Diverse Carbon Use and Sugar Signaling

Sucrose Metabolism: Gateway to Diverse Carbon Use and Sugar Signaling Sucrose metabolism plays pivotal roles in development, stress response, and yield formation, mainly by generating a range of sugars as metabolites to fuel growth and synthesize essential compounds (including protein, cellulose, and starch) and as signals to regulate expression of microRNAs, transcription factors, and other genes and for crosstalk with hormonal, oxidative, and defense signaling. This review aims to capture the most exciting developments in this area by evaluating ( a ) the roles of key sucrose metabolic enzymes in development, abiotic stress responses, and plant–microbe interactions; ( b ) the coupling between sucrose metabolism and sugar signaling from extra- to intracellular spaces; ( c ) the different mechanisms by which sucrose metabolic enzymes could perform their signaling roles; and ( d ) progress on engineering sugar metabolism and transport for high yield and disease resistance. Finally, the review outlines future directions for research on sugar metabolism and signaling to better understand and improve plant performance. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Annual Review of Plant Biology Annual Reviews

Abstract

Sucrose metabolism plays pivotal roles in development, stress response, and yield formation, mainly by generating a range of sugars as metabolites to fuel growth and synthesize essential compounds (including protein, cellulose, and starch) and as signals to regulate expression of microRNAs, transcription factors, and other genes and for crosstalk with hormonal, oxidative, and defense signaling. This review aims to capture the most exciting developments in this area by evaluating ( a ) the roles of key sucrose metabolic enzymes in development, abiotic stress responses, and plant–microbe interactions; ( b ) the coupling between sucrose metabolism and sugar signaling from extra- to intracellular spaces; ( c ) the different mechanisms by which sucrose metabolic enzymes could perform their signaling roles; and ( d ) progress on engineering sugar metabolism and transport for high yield and disease resistance. Finally, the review outlines future directions for research on sugar metabolism and signaling to better understand and improve plant performance.
