Arachis inflata: A New B Genome species of Arachis (Fabaceae)

Bonplandia, 2021
Great efforts have been done to collect germplasm of the Arachis genus in South America, however, many regions still remain underexplored. Under the hypothesis that these regions have new and diverse populations/species of Arachis, several expeditions ...

First Report of Successful Hybridization between Arachis vallsii and Arachis dardani [PDF]

Agrosystems, Geosciences & Environment, 2019
Core Ideas Development of drought tolerance has become a priority in many crops, including peanut. Germplasm collection data show there is variation among wild relatives of peanut for drought tolerance.

Successful crosses between fungal-resistant wild species of Arachis (section Arachis) and Arachis hypogaea [PDF]

Genetics and Molecular Biology, 2015
Peanut (Arachis hypogaea) is the fifth most produced oil crop worldwide. Besides lack of water, fungal diseases are the most limiting factors for the crop. Several species of Arachis are resistant to certain pests and diseases. This study aimed to successfully cross the A-genome with B-K-A genome wild species previously selected for fungal disease ...

Arachis [PDF]

, 2010
Cultivated groundnut (Arachis hypogaea) has a narrow genetic base, probably because of the bottlenecks associated with its origin. Wild Arachis presents a unique opportunity to exploit the underutilised reservoir of potentially useful alleles to broaden the genetic base of A. hypogaea.

Cytological features of penaut genome [PDF]

, 2017
The genus Arachis is composed of 82 species (Krapovickas and Gregory 1994; Valls and Simpson 2005; Valls et al 2013; Santana and Valls 2015) mainly distributed within a large region of South America, which extends from the eastern foothills of the Andes ...

Crossability of Arachis valida and B genome Arachis species

Genetics and Molecular Research, 2015
The peanut (Arachis hypogaea) is an important food crop in much of the tropical and semi-tropical parts of the world. The peanut is an allotetraploid with an AABB genome formula derived from diploids A. duranensis (A genome) and A. ipaënsis (B genome).

Spontaneous generation of diversity inArachisneopolyploids (Arachis ipaënsis×Arachis duranensis)4x replays the early stages of peanut evolution [PDF]

G3 Genes|Genomes|Genetics, 2021
AbstractPolyploidy is considered a driving force in plant evolution and domestication. Although in the genus Arachis, several diploid species were traditionally cultivated for their seeds, only the allotetraploid peanut Arachis hypogaea became the successful, widely spread legume crop.

Cyclophilin A-mediated cis/trans isomerization modulates RIN4 to control intracellular rhizobial infection in legumes. [PDF]

New Phytol
Summary In most legume‐rhizobium symbioses, rhizobial colonization occurs through host‐derived intracellular infection threads, which enable rhizobial recruitment while presumably modulating the host immune system to prevent rejection. To investigate post‐translational regulation of immune responses during rhizobial infection, we focused on Cyclophilin

Inhibition of Aflatoxin Formation in Aspergillus Species by Peanut (Arachis hypogaea) Seed Stilbenoids in the Course of Peanut− Fungus Interaction [PDF]

, 2019
Common soil fungi, Aspergillus flavus and Aspergillus parasiticus, are opportunistic pathogens that invade preharvest peanut seeds. These fungi often produce carcinogenic aflatoxins that pose a threat to human and animal health through food chains and ...

Microbial and Fungal Contamination of Staple Foods in Port Harcourt, Nigeria: Special Attention to High Aflatoxin Risk

Journal of Food Quality and Hazards Control, 2022
Background: Microbial and fungal contamination of agricultural produce has been a health challenge over the years. The present study surveyed microbial and aflatoxin contamination in groundnut, maize, and cowpea collected from Port Harcourt, Nigeria ...
