Beyond Mycorrhizae: A Multi-Kingdom Community in Epiphytic Orchid Roots Reveals Cyanobacteria Intracellular and a Velamen Microbial Refuge. [PDF]
This study redefines orchid ecology by revealing Cattleya purpurata roots host a multi‐kingdom microbiota. We report the first intracellular cyanobacteria in orchids, coexisting with mycorrhizal fungi in the cortex. The velamen functions as a structured refuge for specific, highly diverse microbial communities. ChatGPT (OpenAI) was used only for visual

Diazotrophic bacteria respond to Saharan dust additions [PDF]
Three bioassay experiments were performed to study the effects of nutrient and Saharan dust additions on natural diazotrophic communities in the tropical North Atlantic Ocean. Samples for nucleic acid analysis were collected at the beginning and end of 48 h incubations. TaqMan probes specific to 7 diazotrophic phylotypes, viz. filamentous cyanobacteria

Phosphate solubilizing bacteria stimulate wheat rhizosphere and endosphere biological nitrogen fixation by improving phosphorus content [PDF]
Phosphate (P) availability often limits biological nitrogen fixation (BNF) by diazotrophic bacteria. In soil, only 0.1% of the total P is available for plant uptake.

Genomic and evolutionary comparisons of diazotrophic and pathogenic bacteria of the order Rhizobiales [PDF]
Abstract Background Species belonging to the Rhizobiales are intriguing and extensively researched for including both bacteria with the ability to fix nitrogen when in symbiosis with leguminous plants and pathogenic bacteria to animals and plants. Similarities between the strategies adopted by pathogenic and symbiotic

Characterization of associative diazotrophic bacteria in torch ginger
Associative diazotrophic bacteria perform several processes that promote increased plant development and production, allowing a reduction in the use of agricultural inputs and costs. However, for some species, such as torch ginger, there are still no reports of studies aimed at identifying diazotrophic bacteria associated with this species.

Molecular Characterization of Diazotrophic and Denitrifying Bacteria Associated with Mangrove Roots [PDF]
ABSTRACT An analysis of the molecular diversity of N 2 fixers and denitrifiers associated with mangrove roots was performed using terminal restriction length polymorphism (T-RFLP) of nifH (N 2 fixation) and nirS and nirK
