in Phe-supplied poplars, decreased enzymatic activities of nitrate reductase, glutamate synthase and glutamate dehydrogenase and elevated activities of nitrite reductase, phenylalanine ammonia lyase, glutamine synthetase and asparagine synthase are found in the Phe-treated roots. Accordingly, reduced concentrations of NH4+, NO3- and total N, and enhanced N-use efficiencies are detected in Phe-supplied poplars. The mRNA levels of nitrite reductase, glutamine synthetase 2, NADH-dependent glutamate synthase, glutamate dehydrogenase and asparagine synthetase 2 are downexpressed in Phe-treated roots and/or leaves |
