A Specific Sinorhizobium Flagellin Suppresses Legume Nodulation Through Immune Activation
Plant Biotechnology Journal, EarlyView.ABSTRACT Bacterial flagellin‐activated immunity plays a crucial role in shaping plant‐microbe interactions, leading to either parasitism, mutualism, or commensalism. In the legume‐rhizobium symbiosis, while it has been hypothesized that rhizobial infection involves avoidance of plant immunity following flagellin perception, direct evidence supporting ...

Scientific Reports, 2017 Heterocysts are differentiated cells formed by some filamentous, diazotrophic (dinitrogen-fixing) cyanobacteria. The heterocyst is the site of dinitrogen fixation providing the oxygen-sensitive nitrogenase with a low-oxygen environment.

Hopanoid lipids may facilitate aerobic nitrogen fixation in the ocean. [PDF]
, 2019 Cyanobacterial diazotrophs are considered to be the most important source of fixed N2 in the open ocean. Biological N2 fixation is catalyzed by the extremely O2-sensitive nitrogenase enzyme.

Plant Biotechnology Journal, EarlyView.ABSTRACT Allelopathic rice is increasingly recognised as a promising strategy for sustainable weed management. Resistance to the herbicide quinclorac is widespread in barnyardgrass, but it remains unclear whether allelopathic rice exerts the same defence against herbicide‐susceptible and ‐resistant barnyardgrass. We conducted integrated transcriptomic,

Energy Transduction in Nitrogenase [PDF]
Accounts of Chemical Research, 2018 Nitrogenase is a complicated two-component enzyme system that uses ATP binding and hydrolysis energy to achieve one of the most difficult chemical reactions in nature, the reduction of N2 to NH3. One component of the Mo-based nitrogenase system, Fe protein, delivers electrons one at a time to the second component, the catalytic MoFe protein.

Diversity and Functional Analysis of the FeMo-Cofactor Maturase NifB
Frontiers in Plant Science, 2017 One of the main hurdles to engineer nitrogenase in a non-diazotrophic host is achieving NifB activity. NifB is an extremely unstable and oxygen sensitive protein that catalyzes a low-potential SAM-radical dependent reaction.

Complete Genomes of Symbiotic Cyanobacteria Clarify the Evolution of Vanadium-Nitrogenase. [PDF]
, 2019 Plant endosymbiosis with nitrogen-fixing cyanobacteria has independently evolved in diverse plant lineages, offering a unique window to study the evolution and genetics of plant-microbe interaction.

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.

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 ...

Frontiers in Microbiology, 2018 As inorganic nitrogen compounds are essential for basic building blocks of life (e.g., nucleotides and amino acids), the role of biological nitrogen-fixation (BNF) is indispensible.
