Sucrose Synthase in Legume Nodules Is Essential for Nitrogen Fixation
TL;DR: The role of sucrose synthase in the fixation of N was examined in the rug4 mutant of pea (Pisum sativum L.) plants in which SS activity was severely reduced, and the mutant plants were not viable and appeared to be incapable of effective N fixation, although nodule formation was essentially normal.

Stress-Induced Legume Root Nodule Senescence. Physiological, Biochemical, and Structural Alterations
Manuel A. Matamoros,Lisa M. Baird,P. R. Escuredo,David A. Dalton,Frank R. Minchin,Inaki Iturbe-Ormaetxe,Maria C. Rubio,Jose F. Moran,A. J. Gordon,Manuel Becana +9 more
TL;DR: Nitrate-fed and dark-stressed bean and pea plants were used to study nodule senescence and thiol tripeptides of untreated nodules, indicating sugar deprivation as the primary cause of activity loss.
Stress-Induced Declines in Soybean N2 Fixation Are Related to Nodule Sucrose Synthase Activity
TL;DR: It is proposed that N2 fixation in soybean nodules is mediated by both the oxygen-diffusion barrier and the potential to metabolize sucrose via SS, and the response to environmental perturbation may involve down-regulation of the nodule SS gene.

TL;DR: Common beans (Phaseolus vulgaris L.) were exposed to continuous darkness to induce nodule senescence, and several nodule parameters were investigated to identify factors that may be involved in the initial loss of N2 fixation.

Esther M. González,Pedro M. Aparicio-Tejo,A. J. Gordon,Frank R. Minchin,Mercedes Royuela,Cesar Arrese-Igor +5 more
TL;DR: The effects of water-deficit stress on carbon and nitrogen of Pisum sativum nodules and the activities of phosphoenol pyruvate carboxylase and aspartate aminotransferase) were investigated.
