physiological function | fructan accumulation occurs mainly in the first 2 weeks after anthesis, and a maximal fructan concentration of 2.5 mg fructan per kernel is reached at 16 days after anthesis. Fructan synthesis is catalyzed by 1-SST (sucrose:sucrose 1-fructosyltransferase) and 6-SFT (sucrose:fructan 6-fructosyltransferase), and to a lesser extent by 1-FFT (fructan:fructan 1-fructosyltransferase). Despite the presence of 6G-kestotriose in wheat kernel extracts, the measured 6G-FFT (fructan:fructan 6G-fructosyltransferase) activity levels are low | Triticum aestivum |
