Autoradiogram of TLC-separated, labeled products of endo-β-mannanase digestion of 70% (v/v) methanol-insoluble products formed on incubating microsomal membrane preparations from developing tobacco seeds with GDP-(¹⁴C)-Man (80 μm) and unlabeled UDP-Gal (0.8 mm). C, Membranes from developing seeds of control plant (CTR A, self pollination) 20 d after anthesis. T₁, Membranes from developing seeds of primary transformant FGT 3 (T₁ generation, self-pollination) 20 d after anthesis. M, Man; O, galactomannan octasaccharides; N, galactomannan nonasaccharides; H, higher galactomannan oligosaccharides.
