kernel | developing from anthesis until maturity. 1+6G-Kestotetraose is formed at 5 days after anthesis with both sucrose and 1-kestotriose as substrate and also with sucrose as a single substrate | Triticum aestivum | - |

additional information | 6G-kestotriose is formed by enzyme 6G-FFT, transferring fructose from 1-kestotriose to sucrose, while the 6G-kestotriose levels formed in the assays with added 1-kestotriose and sucrose are rather small. Rapid chain elongation of 6G-kestotriose into 1+6G-kestotetraose and possibly other higher degree of polymerization fructans | Triticum aestivum | ? | - |

General Information | Comment | Organism |
---|---|---|
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 |
