New Phytologist, EarlyView.Summary To address a critical gap in understanding amino acid transport in legume–Rhizobium symbiosis, we investigated the role of symbiosis‐associated USUALLY MULTIPLE ACIDS MOVE IN AND OUT TRANSPORTERS (UMAMITs) in Medicago truncatula nodulation.

Input of nitrogen from N2 fixation to northern grasslands [PDF]
, 2005 Forage legumes form N2-fixing symbioses with rhizobia and may thus make substantial contributions to the N pool in grasslands. However, to optimize their use as sources of N, it is important to elucidate the effects of management factors that influence ...

Acetylene reduction associated with zostera novazelandica Setch. and Spartina alterniflora Loisel., in Whangateau harbour, North Island, New Zealand [PDF]
, 1990 Nitrogen fixation (acetylene reduction) was investigated in Zostera novazelandica Setch. and Spartina alterniflora Loisel., in the North Island of New Zealand.

Science, 2011 Evolution![Figure][1] CREDIT: DR. RACHEL A. FOSTER On early Earth, abiotic processes formed the initial supply of fixed (bioavailable) nitrogen necessary to maintain basic metabolic functions. As life began to flourish, this supply probably couldn't meet demand, and evolutionary pressures selected for a means of biological nitrogen fixation. How did

Natural Variation of a PPR Coding Gene SST1 Confers Salt Tolerance During Soybean Domestication
Plant Biotechnology Journal, EarlyView.ABSTRACT Soil salinity is one of the constraints that adversely affect seedling growth and limit soybean yield. Identifying salt tolerance genes and profiling their allele variants are crucial for elucidating the mechanisms underlying salt tolerance in soybean and enabling the genetic improvement of salt‐tolerant cultivars.

Deep-Sea Archaea Fix and Share Nitrogen in Methane-Consuming Microbial Consortia [PDF]
, 2009 Nitrogen-fixing (diazotrophic) microorganisms regulate productivity in diverse ecosystems; however, the identities of diazotrophs are unknown in many oceanic environments. Using single-cell–resolution nanometer secondary ion mass spectrometry images of ^(

Plant Biotechnology Journal, EarlyView.ABSTRACT Soybean is a critical source of protein and vegetable oil worldwide. Expanding its cultivation into salinity lands represents a promising strategy for increasing production; however, soil salinity severely limits soybean growth by disrupting physiological and metabolic homeostasis.

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 ...

Biosynthesis of Nitrogenase Metalloclusters [PDF]
Chemical Reviews, 2013 Nitrogenase is a complex metalloenzyme that is best known for its function in biological nitrogen fixation.1,2 Harbored in a group of microbes called diazotrophs, nitrogenase catalyzes the reduction of nitrogen (N2) to ammonia (NH3) in a reaction that is usually depicted as N2 + 8H+ + 16MgATP + 8e− → 2NH3 + H2 + 16MgADP + 16Pi.

Comparative proteomics analysis of root and nodule mitochondria of soybean
Plant, Cell &Environment, EarlyView.Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...
