Peanut is widely used as an oilseed crop around the world and as a direct source of human food in the United States and in many other regions the seeds are planted and harvested by hand. Expand
Species relationships among the wild B genome of Arachis species (section Arachis) based on FISH mapping of rDNA loci and heterochromatin detection: a new proposal for genome arrangement
It is confirmed that Arachis ipaensis was the most probable B genome donor for A. hypogaea, and a group of other closely related species are identified. Expand
Molecular analysis of Arachis interspecific hybrids
RAPD marker analysis of 40–chromosome interspecific hybrid derivatives from the four crosses supported previous reports that reciprocal recombination and/or translocations are the predominant mechanisms for exchange of chromosomal segments. Expand
Further Cytogenetic Information on Arachis stenosperma (Leguminosae)
This work sampled a broader area of geographic distribution, represented by an increased number of accessions, and provides further information on karyotypic characteristics of A. stenosperma, finding the potential cytogenetic distinction between coastal and continental populations has vanished.

Genomic affinities in Arachis section Arachis (Fabaceae): molecular and cytogenetic evidence
Sequence data of the trnT-F region provided genome-specific information and showed for the first time that the B and D genomes are more closely related to each other than to the A genome. Expand
An analysis of the B genome speciesArachis batizocoi (Fabaceae)
The presence of translocations is the most likely cause of multivalent formation in A. batizocoi hybrids and Cytological evolution via translocations has apparently been an important mechanism for differentiation in the species. Expand
Diversity of seed storage protein patterns in wild peanut (Arachis, Fabaceae) species
The study showed that great diversity exists for protein profiles and seed storage proteins have potential for aiding species classification and for serving as markers for interspecific hybridization studies. Expand
Genomic in situ hybridization inArachis (Fabaceae) identifies the diploid wild progenitors of cultivated (A. hypogaea) and related wild (A. monticola) peanut species
The results confirm the allopolyploid nature of Arachis hypogaea and strongly support the view that wild A. monticola and cultivated A. ipaensis are the diploid wild progenitors of the tetraploid species studied. Expand
Phylogenetic relations in section Arachis based on seed protein profile
Seed protein profiles of nine diploid species, ten tetraploid accessions, two synthetic amphidiploids and two autotetraploids studied using SDS-polyacrylamide gel electrophoresis suggested considerable homology among these taxa in spite of speciation and ploidy differences. Expand
