2.4.1.10 levansucrase pseudostem the relative expression of the fructan biosynthetic genes 1-SST and 6-SFT, encoding sucrose:sucrose 1-fructosyltransferase and sucrose:fructan 6-fructosyltransferase, respectively, and 6G-FFT/1-FFT isoform 6G-FFT 2 correlates positively with the accumulation of fructans in both blades and pseudostems. Isoform 6G-FFT 2 is highly expressed in cultivar E, that accumulatss the highest levels of fructans in this study 2.4.1.99 sucrose:sucrose fructosyltransferase pseudostem the relative expression of the fructan biosynthetic genes 1-SST and 6-SFT, encoding sucrose:sucrose 1-fructosyltransferase and sucrose:fructan 6-fructosyltransferase, respectively, and 6G-FFT/1-FFT isoform 6G-FFT 2 correlates positively with the accumulation of fructans in both blades and pseudostems. Isoform 6G-FFT 2 is highly expressed in cultivar E, that accumulatss the highest levels of fructans in this study 2.4.1.243 6G-fructosyltransferase pseudostem expression of isoform 6G-FFT1 is associated with low fructan concentrations and positively correlated with fructan exohydrolase gene expression 2.4.1.243 6G-fructosyltransferase pseudostem the relative expression of the fructan biosynthetic genes 1-SST and 6-SFT, encoding sucrose:sucrose 1-fructosyltransferase and sucrose:fructan 6-fructosyltransferase, respectively, and 6G-FFT/1-FFT isoform 6G-FFT 2 correlates positively with the accumulation of fructans in both blades and pseudostems.
