The Phospholipid Composition of Nuclear Subfractions from Germinating Wheat Embryos

The Phospholipid Composition of Nuclear Subfractions from Germinating Wheat Embryos The content of phospholipids in chromatin, nuclear matrix, and nuclear membrane from wheat (Triticum aestivum L.) embryos was studied. Subfractions of intact nuclei from dry embryos were shown to differ in the content and composition of particular phospholipids. Embryo germination resulted in the redistribution of phospholipid between nuclear subfractions. A functional role of structural changes in the nuclear membrane due to this phospholipid redistribution is discussed. It is supposed that these rearrangements change nuclear membrane permeability and its surface charge. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

The content of phospholipids in chromatin, nuclear matrix, and nuclear membrane from wheat (Triticum aestivum L.) embryos was studied. Subfractions of intact nuclei from dry embryos were shown to differ in the content and composition of particular phospholipids. Embryo germination resulted in the redistribution of phospholipid between nuclear subfractions. A functional role of structural changes in the nuclear membrane due to this phospholipid redistribution is discussed. It is supposed that these rearrangements change nuclear membrane permeability and its surface charge.
