Authors: I.P.P. de Menezes, L.V. Hoffmann, T.H. de Lima, A.R. da Silva, V.S. Lucena and P.A.V. Barroso
Mocó cotton belong to the same species as the cultivated species, Gossypium hirsutum, and cultivated forms were mainly landraces but also developed as cultivars, bearing good fiber quality and drought tolerant when cropped as a perennial species. The northeast Brazil crop system based on this cotton type is finished, wi.. Read More»

Contemporary pollen and seed dispersal in natural populations of Bertholletia excelsa (Bonpl.)
Authors: A.B. Baldoni, L.H.O. Wadt, T. Campos, V.S. Silva, V.C.R. Azevedo, L.R. Mata, A.A. Botin, N.O. Mendes, F.D. Tardin, H. Tonini, E.S.S. Hoogerheide and A.M. Sebbenn
Due to the nutritional content and commercial value of its seeds, Bertholletia excelsa is one of the most important species exploited in the Amazon region. The species is hermaphroditic, insect pollinated, and its seeds are dispersed by barochory and animals. Because the fruit set is dependent on natural pollinator activity, g.. Read More»

Population genetic structure of three species in the genus Astrocaryum G. Mey. (Arecaceae)
Authors: N.P. Oliveira, M.S.P. Oliveira, L.C. Davide and S. Kalisz
We assessed the level and distribution of genetic diversity in three species of the economically important palm genus Astrocaryum located in Pará State, in northern Brazil. Samples were collected in three municipalities for Astrocaryum aculeatum: Belterra, Santarém, and Terra Santa; and in two municipalities for .. Read More»

Internal amplification control of PCR for the Glu1-Dx5 allele in wheat
Authors: H.N. Heim, E.S.N. Vieira, L.R.T. Polo, N.K. Lima, G.J. Silva, G.A. Linde, N.B. Colauto and I. Schuster
One of the limiting factors in using dominant markers is the unique amplification of the target fragment. Therefore, failures in polymerase chain reaction (PCR) or non-amplifications can be interpreted as an absence of the allele. The possibility of false negatives implies in reduced efficiency in the selection process in gene.. Read More»

Isolation and characterization of polymorphic microsatellite markers for the chub mackerel (Scomber japonicus) and cross-species amplification in the blue mackerel (S. australasicus)
Authors: F.F. Chen, C.Y. Ma, L.P. Yan, H. Zhang, W. Wang, Y. Zhang and L.B. Ma
In this study, 10 polymorphic microsatellite markers were developed in Scomber japonicus and were examined on 30 individuals collected from the North Pacific. The number of alleles per locus ranged from 4 to 17. The observed and expected heterozygosities per locus ranged from 0.2759 to 0.8621 and from 0.43071 to 0.9177, respec.. Read More»

Genetic diversity analysis in Malaysian giant prawns using expressed sequence tag microsatellite markers for stock improvement program
Authors: K.H. Atin, A. Christianus, N. Fatin, A.C. Lutas, M. Shabanimofrad and B. Subha
The Malaysian giant prawn is among the most commonly cultured species of the genus Macrobrachium. Stocks of giant prawns from four rivers in Peninsular Malaysia have been used for aquaculture over the past 25 years, which has led to repeated harvesting, restocking, and transplantation between rivers. Consequently, a stock impr.. Read More»

Farmer variety exchange along Amazonian rivers influences the genetic structure of manioc maintained in a regional Brazilian Gene Bank
Authors: S.B. Sousa, G.F. Silva, M.C. Dias, C.R. Clement and N.R. Sousa
Knowledge of agro-morphological and genetic variability of germplasm diversity is a prerequisite for its use in breeding. The aim of this study was to characterize the genetic diversity of the manioc (Manihot esculenta) Active Germplasm Bank (AGB) at Embrapa Amazônia Ocidental using microsatellite markers. We evaluated 4.. Read More»

Genetic variability in banana diploids and nonparametric statistics of fragments associated with natural fruit finger drop
Authors: M.A. Rodrigues, E.P. Amorim, C.F. Ferreira, C.A.S. Ledo and J.R.F. Santana
Natural fruit finger drop in bananas is one of the major concerns of producers as well as consumers. The aim of this study was to estimate the genetic diversity among 15 diploid bananas with different levels of resistance to finger drop (RFD) using SSR and ISSR (inter-simple sequence repeat) markers, and assess the possibility..

Authors: S.I.C. Carvalho, L.B. Bianchetti, C.F. Ragassi, C.S.C. Ribeiro, F.J.B. Reifschneider, G.S.C. Buso and F.G. Faleiro
Characterization studies provide essential information for the conservation and use of germplasm in plant breeding programs. In this study, 103 Capsicum frutescens L. accessions from the Active Germplasm Bank of Embrapa Hortaliças, representative of all five Brazilian geographic regions, were characterized based on morp..

Assessment of allelic diversity among drought-resistant cotton genotypes using microsatellite markers
Authors: A. Javaid, F.S. Awan, F.M. Azhar and I.A. Khan
Drought, in conjunction with high temperature, is an important environmental constraint to cotton production. Development of cotton varieties with increased tolerance against adverse environmental conditions has been proposed as effective strategy for ensuring reliable yields. In the present study, 30 simple sequence repeat (S.. Read More»
