Genetic diversity strategy for the management and use of rubber genetic resources: more than 1,000 wild and cultivated accessions in a 100-Genotype core collection. Repositório Alice
SOUZA, L. M. de; LE GUEN, V.; CERQUEIRA-SILVA, C. B. M.; SILVA, C. C.; MANTELLO, C. C.; CONSON, A. R. O.; VIANNA, J. P. G.; ZUCCHI, M. I.; SCALOPPI JUNIOR, E. J.; FIALHO, J. de F.; MORAES, M. L. T. de; GONÇALVES, P. de S.; SOUZA, A. P. de.
Abstract - The rubber tree [Hevea brasiliensis (Willd. ex Adr. de Juss.) Muell. Arg.] is the only plant species worldwide that is cultivated for the commercial production of natural rubber. This study describes the genetic diversity of the Hevea spp. complex that is available in the main ex situ collections of South America, including Amazonian populations that have never been previously described. Genetic data were analyzed to determine the genetic structure of the wild populations, quantify the allelic diversity and suggest the composition of a core collection to capture the maximum genetic diversity within a minimal sample size. A total of 1,117 accessions were genotyped with 13 microsatellite markers. We identified a total of 408 alleles, 319 of which...

In-depth genome characterization of a Brazilian common bean core collection using DArTseq high-density SNP genotyping. Repositório Alice
VALDISSER, P. A. M. R.; PEREIRA, W. J.; ALMEIDA FILHO, J. E.; MÜLLER, B. S. F.; COELHO, G. R. C.; MENEZES, I. P. P. de; VIANNA, J. P. G.; ZUCCHI, M. I.; LANNA, A. C.; COELHO, A. S. G.; OLIVEIRA, J. P. de; MORAES, A. da C.; BRONDANI, C.; VIANELLO, R. P..
Background: Common bean is a legume of social and nutritional importance as a food crop, cultivated worldwide especially in developing countries, accounting for an important source of income for small farmers. The availability of the complete sequences of the two common bean genomes has dramatically accelerated and has enabled new experimental strategies to be applied for genetic research. DArTseq has been widely used as a method of SNP genotyping allowing comprehensive genome coverage with genetic applications in common bean breeding programs. Results: Using this technology, 6286 SNPs (1 SNP/86.5 Kbp) were genotyped in genic (43.3%) and non-genic regions (56. 7%). Genetic subdivision associated to the common bean gene pools (K = 2) and related to grain...
