6.3.1.2 leaf in mature flag leaves, large amounts of isoenzyme GS1 are detected in the connections between the mestome sheath cells and the vascular cells. Parallel to leaf senescence, an increase of a GS1 polypeptide (GS1b) is detected in the mesophyll cytosol of senescing leaves, while the content of another polypeptide (GS1a) in the phloem companion cells remains practically constant in both leaves and stem Triticum aestivum
