Nine polymorphic STR loci in the HLA region in the Shaanxi Han population of China
Authors: H.B. Zhang, S.G. Wei, B. Yu, L. Li and J.H. Lai
A large number of microsatellite genetic markers have been identified in the human leukocyte antigen (HLA) region. We investigated genetic polymorphism of the nine short tandem repeat (STR) loci (D6S276, MOGCA, D6S265, MIB, D6S273, G51152, TAP1CA, RING3CA, and D6S291) in the HLA region in the Shaanxi Han population. Using a fluorescence-labeled multiplex-.. Read More»

Novel polymorphic microsatellite markers for Bellamya and their application in population genetics of three species
Authors: Q.H. Gu, Q.Q. Cheng, X.J. Li and C.J. Zhou
Bellamya is a widely distributed freshwater snail genus in China; however, its genetic diversity is completely unknown. Sixty-five novel microsatellite loci were isolated and characterized from a microsatellite-enriched library of Bellamya aeruginosa genomic DNA. Most of the 65 loci were successfully amplified. We fou.. Read More»

Population divergence and peculiar karyoevolutionary trends in the loricariid fish Hypostomus aff. unae from northeastern Brazil
Authors: J.A. Bitencourt, P.R.A.M. Affonso, L. Giuliano-Caetano, P.L.S. Carneiro and A.L. Dias
Loricariidae (Siluriformes, Hypostominae) is one of the most diverse catfish families. In spite of the wide distribution of loricariids in South America, cytogenetic reports are available for only a few species, mostly from southern and southeastern Brazil. We made the first chromosomal analysis of Hypostomus aff. unae from th.. Read More»

Methylation-sensitive amplified polymorphism-based genome-wide analysis of cytosine methylation profiles in Nicotiana tabacum cultivars
Authors: J. Jiao, J. Wu, Z. Lv, C. Sun, L. Gao, X. Yan, L. Cui, Z. Tang, B. Yan and Y. Jia
This study aimed to investigate cytosine methylation profiles in different tobacco (Nicotiana tabacum) cultivars grown in China. Methylation-sensitive amplified polymorphism was used to analyze genome-wide global methylation profiles in four tobacco cultivars (Yunyan 85, NC89, K326, and Yunyan 87). Amplicons with meth..

Genetic variability at 11 microsatellite markers was analyzed in five naturalized/local Brazilian horse breeds or genetic groups. Blood samples were collected from 328 animals of the breeds Campeira (Santa Catarina State), Lavradeira (Roraima State), Pantaneira (Pantanal Mato-Grossense), Mangalarga Marchador (Minas Gerais Stat..

An let-7 KRAS rs712 polymorphism increases hepatocellular carcinoma risk
Authors: D. Xiong1*, Y.P. Song2*, W. Xiong3 and Y.D. Liang2
KRAS, also known as V-Ki-ras2 Kirsten rat sarcoma viral oncogene homolog, acts as an intracellular signal transducer. The oncogenic KRAS mutation is an essential step in the development of many types of human cancers, including hepatocellular carcinoma. Here we aimed to investigate the relationship between KRAS rs712 polymorphisms and hepatocellular carci.. Read More»

Karyomorphology and karyotype asymmetry in the South American Caesalpinia species (Leguminosae and Caesalpinioideae)
Authors: P.S. Rodrigues, M.M. Souza and R.X. Corr�?ªa
With the purpose of addressing the pattern of karyotype evolution in Caesalpinia species, chromosome morphology was characterized in five species from Brazil, and karyotypic asymmetry was analyzed in 14 species from South America. All accessions had the chromosome number 2n = 24, which was first described here for Caesalpinia laxiflora Tul. and Cenostigma.. Read More»

Is there a relationship between polyploidy and stressful environments? A case study of inselbergs in northeastern Brazil
Authors: S.R. Pitrez, L.A. Andrade, F.N.M. Assis and L.P. Felix
The aim of this study was to examine the hypothesis that plants with higher ploidy levels are selected by environments under more extremely stressful conditions than the same (or closely related) species from less rigorous terrestrial or epiphytic habitats. Therefore, we analyzed the chromosome numbers of 26 species belonging to 21 genera and 13 families .. Read More»

Comparison between different selection indices in energy cane breeding
Authors: A.A.C. de Azeredo, L.L. Bhering, B.P. Brasileiro, C.D. Cruz,L.C.I. Silveira, R.A. Oliveira, J.C. Bespalhok Filho, E. Daros
Sugarcane breeding programs have been adapting to a new market demand: aside from high sucrose yield per hectare, the sector needs new cultivars with higher fiber percentages. The selection of sugarcane clones based on phenotype alone is a complex task. The selected clones should display high performance in a series of yield- .. Read More»
