Nitrate uptake by roots as regulated by nitrate reduction products of the shoot

AB Zioni, Y Vaadia, SH Lips - Physiologia plantarum, 1971 - Wiley Online Library

Correlations between nitrate reduction, protein synthesis and malate accumulation

A Ben‐zioni, Y Vaadia, S Herman Lips - Physiologia plantarum, 1970 - Wiley Online Library
The reduction of nitrate in leaves establishes an ‘excess’ of cations in the tissue which is
rapidly neutralized by the synthesis of malate. Malate synthesized in nitrate‐containing leaves …
