25. Genomic dissection of inbreeding depression: a gate to new opportunities
ABSTRACT Inbreeding depression, reduction in performance of quantitative traits, including reproduction and survival, caused by inbreeding, is a well-known phenomenon observed in almost all experimental, domesticated, and natural populations. In spite of its importance to the fate of a small population and numerous research performed in the last century, the

26. Identification and validation of novel EST-SSR markers in olives
ABSTRACT: The olive (Olea europaea L.) is a leading oil crop in the Mediterranean area. Limited information on the inheritance of agronomic significant traits hinders progress in olive breeding programs, which encourages the development of markers linked to the traits. In this study, we report on the development of 46 olive simple sequence repeat (SSR) marke

27. Behavior of grape breeding lines with distinct resistance alleles to downy mildew (Plasmopara viticola)
Abstract Downy mildew (Plasmopara viticola) is the main grapevine disease in humid regions. In the present investigation, marker-assisted selection (MAS) was used to develop grapevine lines homozygous in loci Rpv1 and Rpv3 for resistance against P. viticola. The experimental populations UFSC-2013-1 (n = 420) and UFSC-2013-2 (n = 237) were obtained by self-po

29. Development and Application of Est-Ssr Markers in Quails
ABSTRACT Aiming at accelerating the application of molecular markers in the genetic improvement of quails, six EST-SSR markers were successfully developed using a bioinformatics method. Polymorphisms of three quail populations (Chinese yellow quail, China black quail and Korean quail) were detected. The results showed that there were 2-6 alleles in six EST-S

30. Microsatellite Analysis of Genetic Diversity in Quail Populations from China
ABSTRACT Polymorphism of three quail communities was analyzed by using 12 microsatellite markers in this paper, aiming to provide scientific references for the evaluation, protection and utilization of quail genetic resources in China. Results demonstrated that the number of observed alleles by 12 microsatellite markers ranges between 4~7. The average polymo

31. CONDICIONES DE CULTIVO DE LA PLANTA MATRIZ Y USO DEL ÁCIDO INDOLBUTÍRICO EN LA PROPAGACIÓN DEL MANDARINO ‘SUNKI’ BAJO ESTAQUILLA
ABSTRACT Citrus rootstocks are obtained from seeds, selecting the apomitic seedlings. However, there is risk of not making the correct selection, due to low level of polyembryony and high heterozygosity in some species or cultivars, such as ‘Sunki’ mandarin. Therefore, obtaining the citrus rootstocks through cuttings may solve the problem. The objective

32. Genetic Variability of Brycon hilarii in a Repopulation Program
ABSTRACT Brycon hilarii, popularly called piraputanga in Brazil, is a species distributed throughout the whole basin of the river Paraguay. In recent years, the species has been on a repopulation program due to its remarkable decline as a wild species in the region. Assessment of the genetic diversity of broodstock and fingerling stocks in repopulation progr

33. Molecular characterization of 'sweet' cassavas (Manihot esculenta) from a germplasm bank in Brazilian Eastern Amazonia
Abstract Genetic variability of a set of 81 accessions of 'sweet' cassavas (Manihot esculenta) collected mostly in the North region of Brazil was investigated with nine microsatellite loci. All loci were polymorphic, with mean of 6.33 alleles per locus. Analyses indicated that 35 multiloci profiles were represented by a single accession, and 46 showed non-un

34. Genetic diversity assessed by microsatellite markers in sweet corn cultivars
Information on genetic diversity is essential to the characterization and utilization of germplasm. The genetic diversity of twenty-two sweet corn cultivars (seventeen open-pollinated varieties, OPV, and five hybrids, H) was investigated by applying simple sequence repeat markers. A total of 257 primers were tested, of which 160 were found to be usable in te

35. Characterization of the complete mitochondrial genome and a set of polymorphic microsatellite markers through next-generation sequencing for the brown brocket deer Mazama gouazoubira
The complete mitochondrial genome of the brown brocket deer Mazama gouazoubira and a set of polymorphic microsatellite markers were identified by 454-pyrosequencing. De novo genome assembly recovered 98% of the mitochondrial genome with a mean coverage of 9-fold. The mitogenome consisted of 16,356 base pairs that included 13 protein-coding genes, two ribosom

36. Type 2 segmental glomangioma - Case report
AbstractGlomus tumors originate from modified perivascular muscle cells. The most common form is the solitary one. The multiple form may be associated with dominant genetic inheritance. We report a case of a patient with hemangiomatous lesions on the calcaneus and wrist since birth. In 6 years, there was progression of lesions throughout the body. Multiple g
