Fig. 7From: Genome-wide identification and characterization of the NF-Y gene family in grape (vitis vinifera L.)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 The fructose content was relatively stable in three successive years (unpublished data), so values for 1Â year are given as reference. Black broken lines denote transcript levels of NF-Y genes, and green broken lines indicate fructose content in grape berriesBack to article page
