Glutamine synthetase (GS) was detected by immunogold localization in the cytosol and plastids of roots of 7-d-old barley (Hordeum vulgare L. cv Klaxon) seedlings grown in the presence or absence of NO3- (15 mM) or NH4+ (30 mM). The number of GS polypeptides changed during root development, and this was affected by N nutrition. There was no evidence of a NO3--inducible root plastid GS.In apical 5- to 10-mm regions of the root the concentration of immunogold labeling of cytosolic GS was higher in… CONTINUE READING
