35 have shown that VvSK1, a protein kinase with sugar signaling function during berry development, positively affects sugar accumulation in grape cells and controls glucose transport through regulating four genes encoding the hexose transporters VvHT3, VvHT4, VvHT5 and VvHT6. Here, VvSK1 (Vitvi15g00840) was not significantly modulated by leafroll viral infections (Fig. 6 and Supplementary Table S6). Here, WEE1 is linked to viral infectious disease.
