abstract：:We compared the response of NO 3 (-) -induced nitrate-reductase (NR) and nitrite-reductase (NIR) levels in virtually carotenoid-free far-red-light-grown mustard (Sinapis alba L.) cotyledons following a photooxidative treatment of the plastids. The cytosolic localization of NR and the plastidic localization of NIR were...
