Última Genetic diversity in section Rhizomatosae of the genus Arachis (Fabaceae) based on microsatellite markers Genet. Mol. Biol. Angelici,Carla M.L.C.D.; Hoshino,Andrea Akemi; Nóbile,Paula Macedo; Palmieri,Dario Abel; Valls,José F. Montenegro; Gimenes,Marcos A.; Lopes,Catalina Romero. The genus Arachis (Fabaceae) native to South America, contains 80 species divided into nine sections, three of which contain species of special economic importance such as the cultivated peanut (Arachis hypogaea), belonging to the section Arachis, and some perennial forage species from sections Caulorrhizae and Rhizomatosae. We used microsatellite markers to assay genetic variability among 77 accessions of four species from section Rhizomatosae, the diploid Arachis burkartii (2n = 2x = 20) and the tetraploid Arachis glabrata, Arachis pseudovillosa and Arachis nitida (2n = 4x = 40). A total of 249 alleles were found in the fifteen loci analyzed and a high degree of intra and interspecific polymorphism was detected. The lowest intraspecific variation...

Ano: 2008 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-47572008000100016 Heterologous microsatellite primer pairs informative for the whole genus Arachis Genet. Mol. Biol. Hoshino,Andrea Akemi; Bravo,Juliana Pereira; Angelici,Carla M.L.C.D.; Barbosa,Andréa V. Gobbi; Lopes,Catalina Romero; Gimenes,Marcos A.. The genus Arachis currently comprises 69 described species, some of which have potential and real value as human and animal foods. These Arachis species have been collected and maintained in germplasm banks to provide material that can be used as sources of genes in breeding programs and for the selection of new cultivars. One of the principal objectives of germplasm conservation is the evaluation of genetic variability, which is best conducted using molecular markers. We investigated the use of heterologous primers to amplify microsatellite loci that could be used to evaluate genetic variability in Arachis germplasm. Fifteen microsatellite primer pairs were tested in 76 accessions of 34 species from the nine Arachis sections. The data indicated that...

Ano: 2006 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1415-47572006000400016 Transferability and use of microsatellite markers for the genetic analysis of the germplasm of some Arachis section species of the genus Arachis Genet. Mol. Biol. Bravo,Juliana Pereira; Hoshino,Andrea Akemi; Angelici,Carla Maria Lara C.D.; Lopes,Catalina Romero; Gimenes,Marcos Aparecido. The Arachis section is the most important of the nine sections of the genus Arachis because it includes the cultivated peanut, Arachis hypogaea. The genetic improvement of A. hypogaea using wild relatives is at an early stage of development in spite of their potential as sources of genes, including those for disease and pests resistance, that are not found in the A. hypogaea primary gene pool. Section Arachis species germplasm has been collected and maintained in gene banks and its use and effective conservation depends on our knowledge of the genetic variability contained in this material. Microsatellites are routinely used for the analysis of genetic variability because they are highly polymorphic and codominant. The objective of this study was to...
