Characterization of a source of resistance to aflatoxin accumulation in maize

Agrosystems, Geosciences & Environment, 2021
Aflatoxinproduced by the fungus Aspergillus flavus (Link:Fr) can accumulate in maize (Zea mays L.) and poses serious human health and economic concerns, especially in sub‐Saharan Africa. Genetic resistance against A.

Diversification of Sinorhizobium populations associated with Medicago polymorpha and Medicago lupulina in purple soil of China

Frontiers in Microbiology, 2023
The double selection of environment adaptation and host specificity forced the diversification of rhizobia in nature. In the tropical region of China, Medicago polymorpha and Medicago lupulina are widely distributed, particularly in purple soil. However,

Genes and genetic mechanisms contributing to fall armyworm resistance in maize

The Plant Genome, 2023
Maize (Zea mays L.) is a crop of major economic and food security importance globally. The fall armyworm (FAW), Spodoptera frugiperda, can devastate entire maize crops, especially in countries or markets that do not allow the use of transgenic crops ...

Mapping Quantitative Trait Loci Associated With Resistance to Aflatoxin Accumulation in Maize Inbred Mp719

Frontiers in Microbiology, 2020
Aflatoxins are carcinogenic and toxic compounds produced principally by fungal species Aspergillus flavus (Link: Fries) and A. parasiticus (Speare), which are common contaminants of food and feed.

Weeds as Reservoirs of Plant Pathogens Affecting Economically Important Crops

EDIS, 2019
Weeds are a major contributor to yield loss and reduction in yield quality in an agricultural setting, competing with the crop for resources like light, water, and nutrients.

Aflatoxin Accumulation in a Maize Diallel Cross Containing Inbred Lines with Expired Plant Variety Protection

Agronomy, 2021
In-field infection of maize (Zea mays L.) ears by the fungus Aspergillus flavus Link:Fr causes pre-harvest aflatoxin contamination of maize grain. Germplasm lines with host-plant resistance to aflatoxin accumulation are available to breeders, but these ...

Comparative Analysis of Multiple GWAS Results Identifies Metabolic Pathways Associated with Resistance to A. flavus Infection and Aflatoxin Accumulation in Maize

Toxins, 2022
Aflatoxins are carcinogenic secondary metabolites produced by several species of Aspergillus, including Aspergillus flavus, an important ear rot pathogen in maize. Most commercial corn hybrids are susceptible to infection by A.

Specificity of salt marsh diazotrophs for vegetation zones and plant hosts

Frontiers in Microbiology, 2012
Salt marshes located on the east coast of temperate North America are highly productive, typically nitrogen-limited, and support diverse assemblages of nitrogen fixing (diazotrophic) bacteria.

Respiratory and Intramuscular Immunization With ChAdOx2-NPM1-NA Induces Distinct Immune Responses in H1N1pdm09 Pre-Exposed Pigs

Frontiers in Immunology, 2021
There is a critical need to develop superior influenza vaccines that provide broader protection. Influenza vaccines are traditionally tested in naive animals, although humans are exposed to influenza in the first years of their lives, but the impact of ...
