Adaptation of cucumber seedlings to low temperature stress by reducing nitrate to ammonium during it’s transportation

Abstract

The higher net NH₄⁺ flux rate in leaves and young tissues may reflect the higher NRA_act in the stem and petiole, which may result in a higher proportion of NO₃^- being reduced to NH₄⁺ during the upward transportation of NO₃^-. The results contribute to an improved understanding of the mechanism of changes in nitrate transportation in plants in response to low-temperature stress.
