abstract：:We have studied the movement and metabolism of oligogalacturonides through shoots of tomato (Lycopersicon esculentum L. cv Rutgers). Oligomers of polygalacturonic acid were prepared by enzyme digestion and gel filtration. These were end-reduced with [(3)H]NaBH4, using an improved reaction method, to yield oligoalditol...
