doi: 10.3389/fpls.2014.00113 Sugar sensing and signaling in plants

Sugars are ubiquitous and critical components for general metabolism. These primary products from photosynthesis affect most, if not all, processes in plant cells by providing skeletons for organic compounds and storing energy for chemical reactions. Sugars also serve as critical signaling molecules in relation to both cellular metabolic status and biotic and abiotic stress response (Rolland et al., 2006; Lastdrager et al., 2014). The diverse and complex networks sugars are involved in warrant a detailed com-prehension of their impact on regulatory and metabolic processes at the cellular and the whole plant level. The current research topic on “Sugar Signaling and Sensing in Plants ” is a combina-tion of primary research articles and review work, and provide novel insights and detailed overviews on the current knowledge of sugars as metabolites and signal molecules.
