Foliar-applied glyphosate substantially reduced uptake and transport of iron and manganese in sunflower (helianthus annuus L.) plants [PDF]

open access: yes, 2006
Evidence clearly shows that cationic micronutrients in spray solutions reduce the herbicidal effectiveness of glyphosate for weed control due to the formation of metal-glyphosate complexes.

Tripartite Symbiosis Between Legumes, Arbuscular Mycorrhizal Fungi and Nitrogen Fixing Rhizobia: Interactions and Regulation

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Legume plants can interact with nitrogen‐fixing rhizobia bacteria and arbuscular mycorrhizal fungi (AMF) simultaneously, forming a tripartite symbiotic association. Co‐inoculation studies performed on a variety of legumes have shown that rhizobia and AMF influence each other when they co‐occur in tripartite association and affect host plant ...

Drought and Herbivory Have Selective Transgenerational Effects on Soybean Eco‐Physiology, Defence and Fitness

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Soybeans, one of the most important legumes, face multiple stresses including drought and herbivory. But the potential transfer of the interactive effects of these stressors onto the transgenerational plants has not been understood. We hypothesised that progeny from stressed parents will have enhanced ecophysiology and defence traits through ...

Nitrogenase: A nucleotide-dependent molecular switch [PDF]

open access: yes, 1994
In the simplest terms, the biological nitrogen cycle is the reduction of atmospheric dinitrogen (N2) to ammonia with the subsequent reoxidation ammonia to dinitrogen (1).

Engineering an Anaerobic Microenvironment to Empower Hydrogenase‐Catalyzed Hydrogen Therapy for Diabetic Wound Healing

open access: yesAggregate, Volume 7, Issue 2, February 2026.
A smart peptide hydrogel integrated with light‐responsive silver nanoclusters establishes a localized anaerobic niche, enabling hydrogenase function in oxygen‐rich biological environments. The system achieves sustained visible‐light‐driven H2 production, effectively scavenges reactive oxygen species, modulates immune responses, and significantly ...

Diverse syntrophic partnerships from deep-sea methane vents revealed by direct cell capture and metagenomics [PDF]

open access: yes, 2008
Microorganisms play a fundamental role in the cycling of nutrients and energy on our planet. A common strategy for many microorganisms mediating biogeochemical cycles in anoxic environments is syntrophy, frequently necessitating close spatial proximity ...

Herbicide toxicity to Nitrospirillum amazonense: assessing bacterial survival and microbial functionality

open access: yesPest Management Science, Volume 82, Issue 2, Page 1842-1852, February 2026.
Herbicides elicit a spectrum of responses in Nitrospirillum amazonense, ranging from the stimulation of metabolic functions (biological nitrogen fixation, IAA production) to significant growth inhibition and acute toxicity. Abstract BACKGROUND Herbicides can exert significant toxicity on nontarget organisms, including plant growth‐promoting bacteria ...

Expression of \u3cem\u3eRhizobium leguminosarum\u3c/em\u3e CFN42 Genes for Lipopolysaccharide in Strains Derived from Different \u3cem\u3eR. leguminosarum\u3c/em\u3e Soil Isolates [PDF]

open access: yes, 1990
Two mutant derivatives of Rhizobium leguminosarum ANU843 defective in lipopolysaccharide (LPS) were isolated. The LPS of both mutants lacked O antigen and some sugar residues of the LPS core oligosaccharides.

Evolution of molecular communication in the permanent Azolla symbiosis

open access: yesNew Phytologist, Volume 249, Issue 4, Page 1666-1674, February 2026.
Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

Accessory Proteins of the Nitrogenase Assembly, NifW, NifX/NafY, and NifZ, Are Essential for Diazotrophic Growth in the Nonheterocystous Cyanobacterium Leptolyngbya boryana

open access: yesFrontiers in Microbiology, 2019
Since nitrogenase is extremely vulnerable to oxygen, aerobic or micro-aerobic nitrogen-fixing organisms need to create anaerobic microenvironments in the cells for diazotrophic growth, which would be one of the major barriers to express active ...
