title: Zeatin Metabolism in Fruits of Phaseolus: Comparison between Embryos, Seedcoat, and Pod Tissues.
abstract: Zeatin metabolites were isolated from seedcoats and pod tissues of Phaseolus vulgaris and P. lunatus. The differences observed previously between P. vulgaris and P. lunatus embryos, i.e. the formation of O-ribosyl derivatives in the former and O-glucosyl derivatives in the latter, could also be detected in seedcoats, although the levels of these metabolites were much lower and there was a concomitant increase of breakdown products (adenine, adenosine and AMP). Inner pod wall tissues of both genotypes metabolized zeatin at a slow rate and the major metabolite was the mononucleotide of zeatin. The array of metabolites recovered was not influenced by the extraction method (cold ethanol or modified Bieleski solution).
