Biological nitrogen fixation in soybean under water restriction and exposed to 1-methylcyclopropene [PDF]
Pesquisa Agropecuária Brasileira, 2016 : The objective of this work was to assess the effects of 1-methylcyclopropene (1-MCP) on traits related with biological nitrogen fixation on 'BRS 268' soybean (Glycine max) subjected to water restriction. Plants were either exposed to drought between 32

GuaB Activity Is Required in Rhizobium tropici During the Early Stages of Nodulation of Determinate Nodules but Is Dispensable for the Sinorhizobium meliloti–Alfalfa Symbiotic Interaction [PDF]
, 2005 The guaB mutant strain Rhizobium tropici CIAT8999-10T is defective in symbiosis with common bean, forming nodules that lack rhizobial content. In order to investigate the timing of the guaB requirement during the nodule formation on the host common ...

Glutaredoxin GRXS17 associates with the cytosolic iron-sulfur cluster assembly pathway [PDF]
, 2016 Cytosolic monothiol glutaredoxins (GRXs) are required in iron-sulfur (Fe-S) cluster delivery and iron sensing in yeast and mammals. In plants, it is unclear whether they have similar functions.

The metabolic fate of doubly labelled lactose-[13C, 15N]ureide after pre-dosing with different ureides [PDF]
European Journal of Clinical Nutrition, 2010 To date, the measurement of the orocaecal transit time (OCTT) with lactose-[(13)C]ureide usually requires a pre-dosing with the analogous substrate in its unlabelled form.In this study, the enzyme induction provoked by different unlabelled sugar ureides in OCTT measurements when using doubly labelled lactose-[(13)C, (15)N]ureide (DLLU) was evaluated ...
