Expression levels of VvNF-Ys and fructose content in different grape varieties. VvNF-YAs (a) VvNF-YBs (b) and VvNF-YCs (c) are divided into three groups. Soluble sugars were extracted from five grape varieties (S1-S5) and then analyzed by HPLC with water as eluent. The fructose content was relatively stable in three successive years (unpublished data), so values for 1 year are given as reference. Black broken lines denote transcript levels of NF-Y genes, and green broken lines indicate fructose content in grape berries
