Rai, AN/ Rowell, P/ Stewart, WDP 1981: 15N2 incorporation and metabolism in the lichen Peltigera aphthosa Willd. - Planta152: 544-552. [RLL List # 114-69 / Rec.# 15206] Keywords: 15N2/ NITROGEN FIXATION/ PELTIGERA/ METABOLISM/ NOSTOC/ PHYCOBIONT/ GLUTAMATE/ GLUTAMINE/ PHYSIOLOGY
Abstract: 3 tables. 8 figures. [Nitrogen fixation by cephalodial Nostoc was transferred to the mycobiont and phycobiont and the initial product was NH4+. Labelled nitrogen also incresed in the amide group of gltamine and glutamate. "When total incorporation of 15N-label was calculated, the overall pattern was found to be rather similar except that, throughout the experiment, the total 15N incorporated into glutamatge was about six times greater than that into the amide group of glutamine."]
