Benzimidazole Anthelmintic Compounds Albendazole and Fenbendazole Show Distinct Toxicity on the Nitrogen Fixing Bacterium Mesorhizobium loti and Its Symbiosis With Lotus japonicus

Environmental Toxicology, EarlyView.
ABSTRACT Veterinary medicines, which reach the soil mostly through the application of contaminated manures, can affect beneficial soil microorganisms, such as nitrogen‐fixing rhizobia bacteria, which engage in important symbiotic associations with plants.

Determination of abundance and symbiotic effectiveness of native rhizobia nodulating soybean and other legumes in Rwanda

Plant-Environment Interactions
Rhizobia diversity in the rhizosphere is one of the key promoters of biological nitrogen fixation between host legumes and microsymbionts, although related complex interaction may depend on various factors.

Diversity of nifH Gene in Culturable Rhizobia from Black Locust (Robinia pseudoacacia L.) Grown in Cadmium-Contaminated Soils

Biology
(1) Background: Rhizobia can promote plant growth by providing essential nutrients such as NH4+ and PO43−; thus, rhizobia that can tolerate the stress of heavy metals will be conducive to the phytoremediation of heavy-metal-contaminated soils. Therefore,

Biochemical analysis of induced resistance in chickpea against broomrape (Orobanche foetida) by rhizobia inoculation

Phytopathologia Mediterranea, 2016
This study examined the capacity of Rhizobium sp. strain PchAZM to reduce parasitism of chickpea by Orobanche foetida under greenhouse conditions, and assessed the relative impact of rhizobia on the expression of chickpea defense response against ...

Crystal structure and biochemical analysis of the polyester‐degrading carboxylesterase SM0281 from the symbiotic legume‐associated rhizobacterium Sinorhizobium (Ensifer) meliloti

The FEBS Journal, EarlyView.
The microbial degradation of synthetic polyesters such as polyethylene terephthalate (PET) is mediated by diverse α/β‐hydrolases, many of which remain poorly characterized. In this study, we investigated the α/β‐hydrolase SM0281 from Sinorhizobium meliloti and found that it exhibits robust carboxylesterase and polyesterase activities toward PET, PCL ...

The costs and benefits of symbiotic interactions: variable effects of rhizobia and arbuscular mycorrhizae on Vigna radiata accessions

BMC Plant Biology
Background The symbiosis among plants, rhizobia, and arbuscular mycorrhizal fungi (AMF) is one of the most well-known symbiotic relationships in nature.

Differential Varietal Responses in Faba Bean Concerning Pea Aphid and Pea Necrotic Yellow Dwarf Virus (PNYDV) When Intercropped With Oat

Journal of Applied Entomology, EarlyView.
ABSTRACT The pest status of pea aphid (Acyrthosiphum pisum H.) in faba bean (Vicia faba L.) cultivation has gained importance because it transmits Pea necrotic yellow dwarf virus (PNYDV), a novel nanovirus in Europe. This study evaluated two faba bean varieties, ‘Fuego’ and ‘GL Sunrise’, grown under sole crop (SC) and intercrop (IC) conditions with oat

In vitro rhizobia response and symbiosis process under aluminum stress [PDF]

, 2018
Aluminium (Al) toxicity is a major problem affecting soil fertility, microbial diversity, and nutrients uptake of plants. Rhizobia response and legume-interaction under Al conditions are still unknown and it is important to understand how to develop and ...

Saprophytic Competence of Inoculated Strain of Groundnut Rhizobium

Madras Agricultural Journal, 1981
Several workers have stressed the use of efficient strains of rhizobia for fuller exploitation of the legumerhizobia symbiosis (Kandasamy and Prasad, 1971; Gasser et al, 1972) Often the successful establishment uf the inoculant rhizobia in soil is ...

Phenolic exudates from orchid seeds as nutrients chemically attract fungi

Journal of Integrative Plant Biology, EarlyView.
Most orchid species require fungi for natural germination, but the molecular mechanism of this symbiosis is poorly understood. Cremastra appendiculata seeds secrete phenolic acids before fungal contact, acting as nutrient molecules to chemically attract its symbiotic fungus Coprinellus disseminatus.
