Variation in the ureide content of Jack Bean during the reproductive stages in response to nitrate [PDF]
Nitrogen is frequently the limiting mineral nutrient for plant productivity and it is essential to obtain an understanding of how this element is assimilated and its metabolism regulated, in crop plants.

Local inhibition of nitrogen fixation and nodule metabolism in drought-stressed soybean [PDF]
Drought stress is a major factor limiting symbiotic nitrogen fixation (NF) in soybean crop production. However, the regulatory mechanisms involved in this inhibition are still controversial.

Carbon dioxide level and form of soil nitrogen regulate assimilation of atmospheric ammonia in young trees. [PDF]
The influence of carbon dioxide (CO2) and soil fertility on the physiological performance of plants has been extensively studied, but their combined effect is notoriously difficult to predict.

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]
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 ...

Expression of Some Molybdoenzyme Genes under Salt Stress Conditions in Chickpea, Bean and Lentil Plants [PDF]
The objective of this work is to isolate mARC, XDH1, AAO3, NIA1, SO and ABA3/LOS5 genes in three legume species submitted to salt stress with molybdenum and nitrogen, the growth conditions (T1: control, T2: both molybdenum and nitrogen added, T3: sodium ...

Glutaredoxin GRXS17 associates with the cytosolic iron-sulfur cluster assembly pathway [PDF]
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.

Plant growth regulators induced urease activity in Cucurbita pepo L. cotyledons [PDF]
This study is aimed to investigate the activity of urease (EC 3.5.1.5, urea amidohydrolase) that catalyzes the hydrolysis of urea in 5-day-old Cucurbita pepo cotyledons subjected to various concentrations of different growth regulators.
