Different Types of Major Storage Seed Proteins in Fagaceae Species

Abstract
The seed proteins of Fagus sylvatica, Quercus Hex and Q. robur, of the Fagaceae family, were extracted by the sequential method of Koie and Nielsen (1977). The storage proteins of Fagns were found to be globulins as has previously been shown in Castanea, a member of the same family. Quercus was found to store glutdins. The amino acid composition and the preliminary characterization by electro-phoresis of Fagus globulins and Quercus glutelins, suggest that both contain proteins similar to the 1 IS globulins of leguminous plants. Both genera showed considerable differences in their albumins. Prolamins were found only in Fagus.
