Sugars and metabolite levels in tubers with
altered expression of the AATP. Tuber material was frozen in liquid
nitrogen and then extracted in trichloroacetic acid to analyze the
levels of Suc (A), Glc (B), Fru (C), Glc1P (D), Glc6P (E), Fru6P (F),
triose-P (G), 3PGA (H), PEP (I), pyruvate (J), isocitrate (K),
α-ketoglutarate (L), malate (M), and PPi (N). Results are means
± se (n = 5).
