Asparagine: an amide of particular distinction in the regulation of symbiotic nitrogen fixation of legumes

S Sulieman, LSP Tran - Critical Reviews in Biotechnology, 2013 - Taylor & Francis
Symbiotic nitrogen fixation is tightly regulated by a range of fine processes at the nodule
level, over which the host plant has overall control through the whole life of the plant. The …

Nodule growth and activity may be regulated by a feedback mechanism involving phloem nitrogen

Recovery of nitrogen fixation after short-term flooding of the nodulated root system of soybean

GC Justino, L Sodek - Journal of Plant Physiology, 2013 - Elsevier
Nitrogen fixation of terrestrial legumes is strongly and rapidly diminished under flooding.
Although recovery is possible with the formation of aerenchyma, information is scarce …
