“…A study of ITS and rDNA also produced a clade containing species from the taxonomic sections Procumbentes, Rhizomatosae, Erectoides, and Trierectoides joined with species from section Arachis (Bechara et al 2010). The reconstruction of phylogenetic relationships from previous studies (Friend et al 2010;Bechara et al 2010;Wang et al 2011) and this study based on DNA sequences show this divergent clade/group, and detailed genome affinity of species within this group needs further investigation using additional genic sequences representing different genome regions to help resolve their relationships.…”

“…Although A. dardani and A. retusa were alternatively at the base when using different genic sequences, the phylogenetic tree based on combined genic sequences of seven loci generated strong support for the basal clade. Species from section Extranervosae were also depicted as one of two terminal lineages in the studies of Friend et al 2010 andWang et al 2011 because they used several species from section Extranervosae and the same DNA sequences. We used only one species, A. retusa, from section Extranervosae, which was absent in their studies, making a slight difference for the basal clade in our study.…”

“…The genetic relationships among species from different sections have been analyzed using SRAP markers among six sections (Ren et al 2010) and SSR markers among seven sections (Koppolu et al 2010). Phylogeny of species of Arachis from all nine sections were reported by Hoshino et al (2006) using SSR markers, Friend et al (2010) using internal transcribed spacer (ITS) and plastid trnT-trnF sequences, Bechara et al (2010) using ITS and 5.8S rDNA sequences, and Wang et al (2011) using ITS. These studies have shown that the molecular phylogeny of species of Arachis was not always consistent with the conventional section classifications, as often, ambiguous or controversial species were assigned to different groups.…”

The genus Arachis (Fabaceae), which originated in South America, consists of 80 species. Based on morphological traits and cross-compatibility among the species, the genus is divided into nine taxonomic sections. Arachis is the largest section including the economically valuable cultivated peanut (A. hypogaea). Seven genic sequences were utilized to better understand the phylogenetic relationships between species of genus Arachis. Our study displayed four clades of species of Arachis. Arachis triseminata was genetically isolated from all other species of Arachis studied, and it formed the basal clade with A. retusa and A. dardani from the most ancient sections Extranervosae and Heteranthae, respectively. Species of section Arachis formed a separated single clade from all other species, within which species having B and D genome clustered in one subgroup and three species characterized with an A genome grouped together in another subgroup. A divergent clade including species from five sections was sister to the clade of section Arachis. Between the sister clades and the basal clade there was a clade containing species from the more advanced sections. Phylogenetic relationships of all the species of Arachis using multiple genic sequences were similar to the phylogenies produced with single-copy genes.

ABSTRACT. The primary gene pool of the cultivated peanut (Arachis hypogaea L., allotetraploid AABB) is very narrow for some important characteristics, such as resistance to pests and diseases. However, the Arachis wild diploid species, particularly those from the section Arachis, still have these characteristics. To improve peanut crops, genes from the wild species can be introgressed by backcrossing the hybrids with A. hypogaea. When diploid species whose genomes are similar to those of the cultivated peanut are crossed, sterile hybrids result. Artificially doubling the number of chromosomes of these hybrids results in fertile synthetic polyploids. The objectives of this study were: 1) to obtain progenies by crossing amphidiploids with the cultivated peanut, and 2) to characterize these two groups of materials (amphidiploids and progenies) so that they 16695 New interspecific hybrids of wild Arachis and A. hypogaea ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (4): 16694-16703 (2015) may be efficiently conserved and used. Using morphological, molecular, and pollen viability descriptors we evaluated one cultivar of A. hypogaea (IAC 503), eight synthetic amphidiploids, and the progenies resulting from four distinct combinations of crossing between IAC 503 and four amphidiploids.

“…On the other hand, PCR amplified fragment length polymorphism (AFLP) data have shown that at least three diploid species with the A genome and three with the non-A genome have small genetic distance compared with the cultigen whereas microsatellite markers have revealed that, although A. duranensis and A. ipae¨nsis are closely related to the cultigen, a small group of other species having the A or non-A genomes could also be possible genome donors (Moretzsohn et al 2004). Likewise, the inferences made on the relationships between the allopolyploids (A. monticola and peanut) and between them and the wild diploid species using ITS and 5.8 rDNA sequences are limited, because of the polytomies obtained in the dendrograms (Friend et al 2010;Bechara et al 2010;Wang et al 2010). Those interpretations were also hampered because the sequences obtained from the tetraploids could have represented only one of the genomes or may have even been a mixture of the sequences from both genomes, as pointed out by Bechara et al (2010).…”
