Comparative analysis of amino acids by GC-MS.
Amino acids of WT were compared with that of transgenic tubers. Amino acids L-leucine (a), serine (b), valyl-valine (c), L-aspartic acid (d), phenylalanine (e), L-asparagine (f), alanine (g), glutamine (h), L-lysine (i), L-valine (j) and L-methionine (k) are shown. Data were normalized to the mean response calculated for WT levels of each replicate that allowed comparison among the replicates. Ribitol served as internal standard. Y-axis represents relative response ratio across WT and transgenic lines (COE-12 and TOE-1). Data represent the mean ± s.e.
