Nitrate Reductase in Barley Roots under Sterile, Low Oxygen Conditions 1

Abstract

Levels of nitrate reductase activity (EC 1.9.6.1.) as high as 11 μmoles nitrite produced/hour gram fresh weight were found in barley (Hordeum vulgare cv. Compana) roots grown under low oxygen conditions. Roots of plants given identical treatment under sterile conditions did not develop the high levels of nitrate reductase activity. The results suggest that the buildup of particulate, reduced viologen-utilizing nitrate reductase reported in barley roots may be caused by bacterial contamination. The nitrate reductase activity in roots grown under low oxygen conditions was not specific for reduced nicotinamide adenine dinucleotide like the assimilatory nitrate reductase (EC 1.6.6.1.) normally found in aerated plant roots.
