Organ-Specific Arabinogalactan-Proteins of Lycopersicon peruvianum (Mill) Demonstrated by Crossed Electrophoresis

Extracts of style, petal, leaf, petiole, stem, and callus derived from stems of wild tomato (Lycopersicon peruvianum) contain characteristic sets of arabinogalactan-proteins. This is demonstrated by crossed electrophoresis in which Yariv reagent, which specifically binds to and precipitates arabinogalactan-proteins, is incorporated into the second gel.
