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
-
after 1 month of growth the activity is twice as high as in N-rich plants

higher activitiy values are found at the beginning of the tuberization, 3-months-old plants, and at the flowering phase, 7 months-old plants
additional information
developing from anthesis until maturity. When sucrose is the sole substrate, 1-kestotriose formation is highest during the first 9 days after anthesis, as well as 1-SST activity for 1-kestotriose formation from sucrose and 6G-kestotriose, after which the latter activity suddenly decreases. Little 1-kestotriose formation is seen in wheat kernels harvested between 9 and 28 days after anthesis whereas no such activity is observed later on during kernel development. 1+6G-kestotetraose formation follows a similar pattern to 1-kestotriose synthesis throughout kernel development although the formed 1+6G-kestotetraose levels are always lower
expression of the 1-SST gene can be observed in roots and leaves of stressed plants
-
higher levels of activity are found in leaf tissue of snow mold-resistant cultivar, which accumulates more fructan than other cultivars
Polymnia sonchifolia
-
activity increase up to 8 months of cultivation, decreasing to initial values at the end of the growth period
-
high 1-SST activity in the vegetative phase and low activity in the sprouting phase. In induced sprouting highest activity is detected in the median region
the onset of fructan synthesis coincides with the increase in 1-SST activity in roots. Expression of the 1-SST gene can be observed in roots and leaves of stressed plants
-
at the flowering stage. At the pre-flowering stage the 1-SST mRNA concentration and the 1-SST activity are higher in root phloem than in xylem
-
the level of the enzyme transcript increases from autumn to early winter in the crown-tissue of all field-grown wheat cultivars examined
