Are phloem amino acids involved in the shoot to root control of NOuptake in plants?
- Authors
Tillard, P; Tillard, Pascal; Passama, L; Passama, Lucien; Gojon, A; Gojon, Alain
- Abstract
Investigates the putative role of phloem amino acids as negative feedback signals for root nitrate ion uptake in Ricinus communis. Effect of nitrogen (N) deprivation on ion influx and downward phloem amino acid transport; Variation in the decrease of individual amino acids; Effect of localized N-deprivation in whole and split-root plants; Differential transport of amino acids.
