Introducción. Se ha informado que los hongos fitopatógenos representan las principales pérdidas económicas a nivel global en diferentes tipos de cultivos, entre los que se encuentran hortalizas como Brassica Oleracea var. capitata. Objetivos. Identificar los posibles hongos fitopatógenos asociados a...

Draft genome sequence of a halotolerant plant growth-promoting bacterium Pseudarthrobacter oxydans NCCP-2145 isolated from rhizospheric soil of mangrove plant Avicennia marin

BACKGROUND Limited knowledge exists regarding the diversity of mangrove plant-associated Pseudarthrobacter species. This study presents the first draft genome and phylogenetic analysis of a Pseudarthrobacter oxydans NCCP-2145, isolated from the rhizospheric soil of Aviciana marina, a native mangrove plan...

Arbuscular mycorrhizal fungi activity in the rhizosphere of tree seedlings subjected to residual herbicides

Braz. j. biol; 83 (), 2023
Abstract Trees occurring on the margins of agricultural areas can mitigate damage from residual herbicides. Rhizospheric microbial activity associated with trees is one of the main remedial capacity indicators. The objective of this study was to evaluate the rhizospheric microbiological activity in tree ...

Antagonic and plant growth-promoting effects of bacteria isolated from mine tailings at El Fraile, Mexico

Rev. argent. microbiol; 52 (3), 2020
Abstract Mine tailings contain high concentrations of heavy metals such as As, Pb, Cu, Mn, andFe, which are detrimental to the health of humans and the environment. In tailings at the ElFraile mine in Guerrero, Mexico, some plant species are apparently tolerant of heavy metals andcan be found growing in ...

Adaptation of plants to high-calcium content kart regions: possible involvement of symbiotic microorganisms and underlying mechanisms

Braz. j. biol; 80 (1), 2020
Abstract Rhizosphere microorganisms and endophytes can help their hosts absorb nutrients and regulate the levels of plant hormones. Moreover, they can modulate the expressions of host genes, assist hosts in eliminating reactive oxygen species (ROS) and secreting volatile organic compounds. Therefore, rhi...

Evaluation of leaf and root absorptions of glyphosate in the growth of coffee plants

Arq. Inst. Biol; 87 (), 2020
Intoxication by dispersion of glyphosate droplets in coffee seedlings is common and, in addition to the problem of drift, there are reports of contamination of this herbicide to a nontarget plant via the rhizosphere. Hydroponics allows the comparison of the translocation of the glyphosate absorbed by the...

Petroleum contamination and bioaugmentation in bacterial rhizosphere communities from Avicennia schaueriana

Braz. j. microbiol; 49 (4), 2018
ABSTRACT Anthropogenic activity, such as accidental oil spills, are typical sources of urban mangrove pollution that may affect mangrove bacterial communities as well as their mobile genetic elements. To evaluate remediation strategies, we followed over the time the effects of a petroleum hydrocarbon deg...

Trichoderma harzianum MTCC 5179 impacts the population and functional dynamics of microbial community in the rhizosphere of black pepper (Piper nigrum L )

Braz. j. microbiol; 49 (3), 2018
Abstract Employing Illumina Hiseq whole genome metagenome sequencing approach, we studied the impact of Trichoderma harzianum on altering the microbial community and its functional dynamics in the rhizhosphere soil of black pepper (Piper nigrum L.). The metagenomic datasets from the rhizosphere with (tre...

Arbuscular mycorrhizal fungal communities in the rhizosphere of a continuous cropping soybean system at the seedling stage

Braz. j. microbiol; 49 (2), 2018
Abstract Arbuscular mycorrhizae (AM) fungi play a crucial role in the growth of soybean; however, the planting system employed is thought to have an effect on AM fungal communities in the rhizosphere. This study was performed to explore the influence of continuous soybean cropping on the diversity of Arb...

Reintroducing plant coverage in a tropical wetland contaminated with oil and sulfate: rhizosphere effects on Desulfovibrio populations

Rev. biol. trop; 66 (2), 2018
Abstract The Mexican tropical wetland is a coastal system with capacity to support the contamination derived from the extractive industry and the transformation of crude oil, due to its high plant biodiversity and the presence of rhizospheric reducing sulphate bacteria from plants tolerant to crude oil. ...
