Shiraz Focus V4 [Full Version] VERIFIED

At the metabolite level, a cluster of mono- and disaccharides was first detected in both cultivars at veraison stage, followed by the monosaccharide cluster of fructose, glucose and fructose, which increased at post-veraison. In both cultivars, sucrose peaked at post-veraison stage and showed no further changes thereafter. These results are in accordance with previous reports [ 41 ] and confirm sugar accumulation in maturing berry skin [ 39 ]. The exceptions were glucose-6-phosphate (G6P) and fructose-6-phosphate (F6P) that displayed very little change throughout the ripening. This suggests that higher amount of the hexose phosphates might derive from the fermentative pathway, otherwise it might be reused for biosynthesis of polyphenolic compounds [ 17 ]. Chlorogenic acid derivatives dominated in both cultivars with only the peak of F3,5CQA displayed at veraison in CS, while no peaks were observed in Shiraz. The later is in accordance with previous reports [ 16 ].

In the present study, a total of 57 transcripts involved in the primary metabolism changed significantly from veraison to post-veraison stage (Kruskal-Wallis test, p
