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.

Construction of an introgression line population for cultivated peanut (<i>Arachis hypogaea</i>) to facilitate breeding with wild relatives <i>Arachis batizocoi</i> and <i>Arachis stenosperma</i>. [PDF]

Front Plant Sci
Cultivated peanut is susceptible to several highly damaging pests, pathogens and abiotic stressors, largely due to its very narrow genetic base. However, a ploidy barrier exists between cultivated and highly resistant wild peanuts, which makes the process of interspecific hybridization relatively laborious and beyond the scope of ...

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.

Characterization and Comparative Analysis of RWP-RK Proteins from Arachis duranensis, Arachis ipaensis, and Arachis hypogaea

International Journal of Genomics, 2020
RWP-RK proteins are important factors involved in nitrate response and gametophyte development in plants, and the functions of RWP-RK proteins have been analyzed in many species. However, the characterization of peanut RWP-RK proteins is limited. In this study, we identified 16, 19, and 32 RWP-RK members from Arachis duranensis, Arachis ipaensis, and ...

Cytomorphological investigations in wide cross of Arachis involving Arachis hypogaea and an amphidiploid (Arachis correntina x Arachis helodes)

Electronic Journal of Plant Breeding, 2014
Inter-specific cross of Arachis hypogaea (2n=4x=40) and Arachis correntina x Arachis helodes (2n=2x=20) yielded the unstable triploid and sterile derivatives. The ploidy level of this triploid (3x) was then doubled with colchicine to get an unstable hexaploid derivative.

The genome sequences of Arachis duranensis and Arachis ipaensis, the diploid ancestors of cultivated peanut [PDF]

Nature Genetics, 2016
Cultivated peanut (Arachis hypogaea) is an allotetraploid with closely related subgenomes of a total size of ∼2.7 Gb. This makes the assembly of chromosomal pseudomolecules very challenging. As a foundation to understanding the genome of cultivated peanut, we report the genome sequences of its diploid ancestors (Arachis duranensis and Arachis ipaensis).
