Following germination of the castor bean (Ricinus communis L.) seed, levels of phytin decline in both the endosperm and the embryo. However, as seedling growth continues, phytin increase in the latter to a level exceeding that present in the mature dry embryo, while phytin declines concomitantly in
Energy dispersive x-ray analysis was used to study the composition of certain protein body components in Cucurbita maxima cotyledons. The globoid crystal was rich in phosphorus, potassium, and magnesium. This elemental composition provides further evidence that the globoid crystal in squash
The degradation of phytin in germinating mung bean seeds has been found to be associated with the increased activity of phytase in the cotyledon. In the differentiated embryo the increase of this activity is very low all throughout the growth periods studied. Phytase appears in the cotyledon during
The elemental composition of globoids in the protein bodies of Protea compacta cotyledons was studied by means of energy dispersive X-ray analysis. The globoid crystal was rich in phosphorus and calcium with lesser amounts of magnesium and potassium suggesting the presence of phytin in these
