The aim of this study was to analyze genetic diversity and population structure among varieties of White (N = 40), Red (N = 32), and Black (N = 31) Morada Nova hair sheep from flocks in the northeastern Brazilian semiarid region. Fifteen nuclear microsatellite markers and two regions of mitochondrial DNA were used. The intra-p.. Read More»

Auxin response factors (ARFs) participate in the transcriptional regulation of a series of biological processes related to growth and development. The ARF genes comprise a large multigene family in plants. Recently, a draft of the full cucumber (Cucumis sativus) genome assembly has been released; however, none of the ARF genes have been characterized. We .. Read More»

We analyzed meat samples of nine pure lines of rabbit and its 37 hybrid combinations by sequencing and single-strand conformation polymorphism techniques to explore genetic polymorphisms of all the three exon regions and part of the 5'-regulatory region of the myostatin (MSTN) gene. Thus, we detected a single nucleotide mutati.. Read More»

For genetic evaluation of beef cattle, univariate or bivariate analyses are often performed as an alternative to decrease the complexity of matrices and mathematical models compared to multivariate analysis, which considers a larger number of joint traits. The use of bivariate methods to calculate genetic predictors may cause .. Read More»

The phylogeny of a phylogenetically poorly known family, Phytolaccaceae sensu lato (s.l.), was constructed for resolving conflicts concerning taxonomic delimitations. Cladistic analyses were made based on 44 sequences of the internal transcribed spacer of nuclear ribosomal DNA from 11 families (Aizoaceae, Basellaceae, Didiereaceae, Molluginaceae, Nyctagin..

This study investigated 5 single nucleotide polymorphism (SNP) haplotypes in susceptibility genes for coronary artery disease (CAD) and the putative involvement of these SNPs in CAD in the Chinese Han population. From March 2008 to June 2009, we selected 119 CAD patients and 115 subjects not related to the CAD of Chinese Han o.. Read More»

Testicular seminoma has become the most common solid malignancy in young men, especially in the 20s group. We obtained the gene expression profile of human testicular seminoma cells from NCBI, identified the differentially expressed genes of testicular seminoma cells of different stages, and constructed the regulation networks of different stages of testi..

Numerous studies have evaluated the association between the maternal C677T polymorphism in the methylenetetrahydrofolate reductase (MTHFR) gene and congenital heart defect (CHD) risk in the Chinese Han population. However, the specific association is still controversial. Six separate studies with 1089 subjects in the Chinese Han population on the relation.. Read More»

We examined the genetic diversity of papaya (Carica papaya) based on morpho-agronomic and molecular data. Twenty-seven genotypes grown in Brazil were analyzed with 11 AFLP primer combinations, 23 ISSR markers, 22 qualitative, and 30 quantitative descriptors. For the joint analyses, we used the Gower algorithm (Joint Gower) and the average value of the ind.. Read More»

The aim of this study was to determine whether single nucleotide polymorphisms (SNPs) of bovine Dickkopf homolog 4 (DKK4) are associated with body measurement traits in Qinchuan cattle. By using PCR-SSCP technology and DNA sequencing, we discovered 5 DKK4 SNPs in Qingchuan cattle, including -65G>A and -77G>T in the 5êÂ?Â?-untranslated region, 1532C.. Read More»
