Host-Pathogen Interactions : XXIV. Fragments Isolated from Suspension-Cultured Sycamore Cell Walls Inhibit the Ability of the Cells to Incorporate [C]Leucine into Proteins.

abstract：:Nitrate reductase activity was induced by nitrate in green corn (Zea mays) leaves in either light or darkness. The induction process required oxygen in darkness but not in light. A light treatment was required before the enzyme could be induced in etiolated leaves.The capacity for nitrate reductase induction by nitrat...
