Carbon cycling in Anabaena sp. PCC 7120. Sucrose synthesis in the heterocysts and possible role in nitrogen fixation
(American Society of Plant Biologist, 2007-03)
Nitrogen (N) available to plants mostly originates from N2 fixation carried out by prokaryotes. Certain cyanobacterial species contribute to this energetically expensive process related to carbon (C) metabolism. Several ...
Sucrose is involved in diazotrophic metabolism of the heterocyst-forming cyanobacterium Anabaena sp
(Elsevier Science, 2002-02)
Sucrose synthase (SuS) expression was studied in the filamentous, nitrogen-fixing cyanobacterium Anabaena sp. PCC 7119. SuS activity, SusA polypeptide, and susA mRNA levels were lower in cells cultured diazotrophically ...
Comportamiento de inoculantes para soja en la zona sur de la provincia de Santa Fe, Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2007)
La soja fija el nitrógeno atmosférico en simbiosis mutualista con Bradyrhizobium japonicum y/o Sinorhizobium, mediante la Fijación Biológica del Nitrógeno (FBN). El uso de especies capaces de nodular vigorosamente y de ...
Sucrose synthase is involved in the conversion of sucrose to polysaccharides in filamentous nitrogen-fixing cyanobacteria
(Springer, 2008-06)
Higher plants and cyanobacteria metabolize sucrose (Suc) by a similar set of enzymes. Suc synthase (SuS, UDP-glucose: D-fructose 2- -D-glucosyl transferase, EC 2.4.1.13) catalyses the synthesis and cleavage of Suc, and in ...
Drivers of cyanobacteria dominance, composition and nitrogen fixing behavior in a shallow lake with alternative regimes in time and space, Laguna del Sauce (Maldonado, Uruguay)
(Springer, 2018-05-03)
Laguna del Sauce, one of the main drinking water sources in Uruguay, is an eutrophic shallow lake with high temporal variation of inorganic turbidity caused by extreme wind events. During low turbidity periods, high ...
Effects of forest preservation, livestock exclusion and use of shrubs as potential nurses on planting success of an endangered tree
(Wiley Blackwell Publishing, Inc, 2021-05-27)
Domestic livestock are widespread in seasonally dry forests, likely causing forest degradation and limiting tree seedling establishment. Shrubs can play an important role in facilitating tree regeneration, by protecting ...
The importance of denitrification performed by nitrogen-fixing bacteria used as inoculants in South America
(Springer, 2020-06)
Replacing synthetic fertilizers by biological nitrogen fixation (BNF) is regarded as an environmentally sound practice, but some diazotrophic bacteria are capable of emitting N2O by denitrification. The ability to use ...
Metabolic features involved in drought stress tolerance mechanisms in peanut nodules and their contribution to biological nitrogen fixation
(Elsevier Ireland, 2017-10)
Legumes belong to the most important crops worldwide. They increase soil fertility due their ability to establish symbiotic associations with soil microorganisms, known as rhizobia, capable of fixing nitrogen from the ...
Exploring the Ancestral Mechanisms of Regulation of Horizontally Acquired Nitrogenases
(Springer, 2015-10)
The vast majority of Pseudomonas species areunable to fix atmospheric nitrogen. Although severalstudies have demonstrated that some strains belonging tothe genus Pseudomonas sensu stricto do have the ability tofix nitrogen ...
