Discs of outer pericarp were excised from mature green tomato (Lycopersicon esculentum Mill.) fruit and kept in sterile tissue culture plates for 4 d, including 2 d of incubation with D-[U-13C]glucose. Cell walls were prepared and the water-soluble, pectic, and hemicellulosic polymers were extracted...
