Metabolism of sucrose, glucose, malic acid and succinic acid: gene expression and metabolite content. Relative quantification of sucrose, α-glucose, malic acid and succinic acid is based on characteristic chemical shift (δ 5.39, δ 5, 17, δ 2.67 and δ 2, 62, respectively), and corresponding peak intensity. Malate and succinate contents are higher at pre-véraison stages peaking at EL 32 whereas contents in sucrose and α-glucose increase at post-véraison stages reaching maximal levels at EL 38. Expression levels of genes coding for sucrose synthase (VVTU16744_s_at), sucrose-phosphate synthase 1 (VVTU4280_at), sucrose phosphatase (VVTU21174_s_at), phosphoenolpyruvate carboxylases (VVTU12208_at, VVTU19092_at), glyoxysomal precursor of malate dehydrogenase (VVTU4095_at), succinate-semialdehyde dehydrogenase (VVTU35625_s_at) are based on microarray.
