Sucrose Synthase and Fructokinase Are Required for Proper Meristematic and Vascular Development Open
Sucrose synthase (SuSy) and fructokinase (FRK) work together to control carbohydrate flux in sink tissues. SuSy cleaves sucrose into fructose and UDP-glucose; whereas FRK phosphorylates fructose. Previous results have shown that suppressio…

An Overview of Sucrose Synthases in Plants Open
Sucrose is the end product of photosynthesis and the primary sugar transported in the phloem of most plants. Sucrose synthase (SuSy) is a glycosyl transferase enzyme that plays a key role in sugar metabolism, primarily in sink tissues. SuS…

Plant Fructokinases: Evolutionary, Developmental, and Metabolic Aspects in Sink Tissues Open
Sucrose, a glucose-fructose disaccharide, is the main sugar transported in the phloem of most plants and is the origin of most of the organic matter. Upon arrival in sink tissues, the sucrose must be cleaved by invertase or sucrose synthas…

Suppression of sucrose synthase affects auxin signaling and leaf morphology in tomato Open
Metabolic enzymes have been found to play roles in plant development. Sucrose synthase (SUS) is one of the two enzyme families involved in sucrose cleavage in plants. In tomato, six SUS genes have been found. We generated transgenic tomato…

Arabidopsis Fructokinases Are Important for Seed Oil Accumulation and Vascular Development Open
Sucrose (a disaccharide made of glucose and fructose) is the primary carbon source transported to sink organs in many plants. Since fructose accounts for half of the hexoses used for metabolism in sink tissues, plant fructokinases (FRKs), …

The tomato plastidic fructokinase <i>Sl<span>FRK</span>3</i> plays a role in xylem development Open
Summary Plants have two kinds of fructokinases ( FRK s) that catalyze the key step of fructose phosphorylation, cytosolic and plastidic. The major cytosolic tomato FRK , Sl FRK 2 , is essential for the development of xylem vessels. In orde…
