Chromosome number and cytogenetics of Euphorbia heterophylla L.

Authors: J.R. Aarestrup, D. Karam and G.W. Fernandes

Euphorbia heterophylla L. (Euphorbiaceae) is a herbaceous species of great economic importance due to its invasive potential and consequent damage to agriculture and pasture land. For the first time, we provide information on its chromosome number, morphology, and behavior of mitotic chromosomes. Seeds were germinated and subm.. Read More»

Estimation of taurindicine hybridization of American Zebu cattle in Brazil

Authors: P. Ripamonte, M. Baccaglini, A.S.M. Cesar, L.G.G. Figueiredo, J.C.C. Balieiro, A.R. Caetano and F.V. Meirelles

Our objective was to estimate Bos primigenius taurus introgression in American Zebu cattle. One hundred and four American Zebu (Nellore) cattle were submitted to mtDNA, microsatellite and satellite analysis. Twenty-three alleles were detected in microsatellite analysis, averaging 4.6 ± 1.82/locus. Variance component com.. Read More»

Characterization of Fusarium species section Liseola by restriction analysis of the IGS region

Authors: M.H. Heng, S. Baharuddin and Z. Latiffah

Fusarium species section Liseola namely F. fujikuroi, F. proliferatum, F. andiyazi, F. verticillioides, and F. sacchari are well-known plant pathogens on rice, sugarcane and maize. In the present study, restriction analysis of the intergenic spacer regions (IGS) was used to characterize the five Fusarium species isolated from .. Read More»

Characterization of nine novel microsatellite loci for the Venus clam (Cyclina sinensis)

Authors: J.X. Wang, T.J. Xu, L. Wei, F.X. Meng and R.X. Wang

The Venus clam, Cyclina sinensis, is one of the most important bivalves in China marine aquaculture. Using (CA)15-enriched genomic libraries of this species, nine novel polymorphic microsatellite loci were isolated and characterized. The mean number of observed alleles per locus was 16 (range 8-24). The observed and expected h.. Read More»

Development of novel polymorphic microsatellite markers for the silver fox (Vulpes vulpes)

Authors: S.Q. Yan, C.Y. Bai, S.M. Qi, Y.M. Li, W.J. Li and J.H. Sun

The silver fox (Vulpes vulpes), a coat color variant of the red fox, is one of the most important fur-bearing animals. To date, development of microsatellite loci for the silver fox has been limited and mainly based on cross-amplification by using canine SSR primers. In this study, 28 polymorphic microsatellite markers were isolated and identified for sil.. Read More»

Pattern of silver nitrate-staining during meiosis and spermiogenesis in testicular lobes of Antiteuchus tripterus (Heteroptera: Pentatomidae)

Authors: H.V. Souza, M.M.U. Castanhole, H.E.M.C. Bicudo and M.M. Itoyama

The pattern of silver nitrate (Ag)-staining differed among testicular lobes of Antiteuchus tripterus. In general, these differences are in regard to the number, size, shape, coloring intensity, and location of the stained bodies or masses, observed during meiosis and spermiogenesis. These characteristics were similar in lobes .. Read More»

Expression of hypoxia-inducible factor-1�± during ovarian follicular growth and development in Sprague-Dawley rats

Authors: Z.H. Zhang, L.Y. Chen, F. Wang, Y.Q. Wu, J.Q. Su, X.H. Huang, Y. Cheng and Z.C. Wang

Hypoxia-inducible factor-1α (HIF-1α) has been identified as a transcription factor that is involved in diverse physiological and pathological processes in the ovary. In this study, we examined whether HIF-1α is expressed in a cell- and stage-specific manner during follicular growth and development in the mammalian ovaries. Using immunohi.. Read More»

Position effect variegation and epigenetic modification of a transgene in a pig model

Authors: Z. Yin, Q.R. Kong, Z.P. Zhao, M.L. Wu, Y.S. Mu, K. Hu1 and Z.H. Liu

Sequences proximal to transgene integration sites are able to regulate transgene expression, resulting in complex position effect variegation. Position effect variegation can cause differences in epigenetic modifications, such as DNA methylation and histone acetylation. However, it is not known which factor, position effect or.. Read More»

Cloning and molecular modeling of Litopenaeus vannamei (Penaeidae) C-type lectin homologs with mutated mannose binding domain-2

Authors: F.H.F. Costa, N.S.M.S. Valen�§a, A.R.B.P. Silva, G.A. Bezerra4, B.S. Cavada and G. R�¡dis-Baptista

C-type lectins are animal proteins that contain at least one carbohydrate recognition domain (CRD) capable of mediating sugar and calcium binding. Carbohydrate recognition is directly required for some biological functions, including the innate immune response. We cloned two novel C-type lectin (CTL) precursors from the commer.. Read More»

Positions of pluripotency genes and hepatocyte-specific genes in the nucleus before and after mouse ES cell differentiation

Authors: K. Udagawa and T. Ohyama,

Spatial positioning of genes in the cell nucleus plays an important role in the regulation of genomic functions. Evidence for changes in gene positioning associated with transcriptional activity has been reported. However, our understanding of this phenomenon is still quite limited. We examined how pluripotency genes and hepat.. Read More»
