Additional file 4: Figure S3. of Genome-wide identification and characterization of the NF-Y gene family in grape (vitis vinifera L.)

Expression levels of VvNF-Ys and total sugar 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 The total content was relatively stable in three successive years (unpublished data), so values for 1 year are given as reference.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 blue broken lines indicate total sugar content in grape berries. (PDF 224 kb)
