Nitrate Reduction by Cassava

摘要

Nitrate reductase (NR) was assayed in vivo in cassava (Manihot esculentaCrantz). Activity in the leaves ranged from 0 to 2.51μmole of NO3−reduced g−1h−1, with no activity in the younger leaves (leaf 1 on top). NR activity was localized in the sides and toward the tip of the lobes of th
