Genetic diversity among exotic cotton accessions as for qualitative and quantitative traits

Authors: L.P. de Carvalho, F.J.C. Farias, J.I.S. Rodrigues, N.D. Suassuna and P.E. Teodoro

Studying genetic diversity among a group of genotypes is important in genetic breeding because identifying hybrid combinations of greater heterotic effect also increases the chance of obtaining plants with favorable allele combinations in an intra-population selection program. The objective of this study was to compare differe.. Read More»

Chromosomal diversity in Hypostomus (Siluriformes, Loricariidae) with emphasis on physical mapping of 18S and 5S rDNA sites

Authors: J.B. Traldi D.R. Blanco M.R. Vicari J.F. Martinez R.L. Lui A.V. Barros R.F. Artoni O. Moreira-Filho

We examined chromosomes of three species of the genus Hypostomus, in order to contribute to the understanding of the karyotype evolution of this group. Specimens of H. ancistroides and H. nigromaculatus displayed differences in karyotype formulas, distribution and location of heterochromatin and nucleolus organizer regions when compared to other populations ..

Dynamics of 45S rDNA sites in the cell cycle: fragile sites and chromosomal stability in Lolium and Festuca

Authors: L.C. Rocha, G.A. Silva, F.O. Bustamante, R.A.D. Silveira,A. Mittlemann and V.H. Techio

Analyses carried out with fluorescence in situ hybridization (FISH) in C-metaphases of the Lolium-Festuca complex have shown the occurrence of spontaneous fragile sites (FSs) in 45S rDNA regions. FSs are expressed as gaps but they do not result in breaks or chromosomal fragments in these species. These gaps have high DNA conde.. Read More»

Iron translocation in Pleurotus ostreatus basidiocarps: production, bioavailability, and antioxidant activity

Authors: M.E. Yokota1, P.S. Frison1, R.C. Marcante1, L.F. Jorge1, J.S. Valle1, D.C. Dragunski2, N.B. Colauto1 and G.A. Linde10

Translocation of minerals from substrate to mushrooms can change the medicinal characteristics, commercial value, and biological efficiency of mushroom. In the present study, we demonstrated that addition of iron to the substrate reduces the yield of Pleurotus ostreatus mushroom. The biological efficiency of the mushroom varied from 36.53% on the unsupple.. Read More»

Evaluation of the antimutagenic activity and mode of action of the fructooligosaccharide inulin in the meristematic cells of Allium cepa culture

Authors: M.O. Mauro, J.R. Pesarini, M.A. Marin-Morales, M.T.F.D. Monreal, A.C.D. Monreal, M.S. Mantovani and R.J. Oliveira

This study evaluated the mutagenicity and antimutagenicity of inulin in a chromosomal aberration assay in cultures of the meristematic cells of Allium cepa. The treatments evaluated were as follows: negative control - seed germination in distilled water; positive control - aqueous solution of methyl methanesulfonate (.. Read More»

Improvement in the carcass traits and meat quality of growing-finishing Rongchang pigs by conjugated linoleic acid through altered gene expression of muscle fiber types

Authors: J.X. Huang, R.L. Qi, X.L. Chen, X.Y. You, X.Q. Liu, F.Y. Yang and Z.H. Liu

A total of 160 Rongchang pigs (26.76 ± 1.78 kg) were randomly assigned to 5 dietary treatment groups until their body weight (BW) reached 90 kg. The diets were supplemented with 0, 0.5, 1.0, 1.5, and 2.0% conjugated linoleic acid (CLA). Our results showed that the 1.0 to 2.0% CLA-fed pigs had less back fat deposition wh.. Read More»

A novel single-nucleotide polymorphism in the 5' upstream region of the prolactin receptor gene is associated with fiber traits in Liaoning cashmere goats

Authors: J.P. Zhou, X.P. Zhu, W. Zhang, F. Qin, S.W. Zhang and Z.H. Jia

The most important traits of Chinese Liaoning cashmere goat fiber are fiber diameter, weight, and length. We looked for polymorphisms and their possible association with cashmere fiber traits in the 5' upstream region (5' UTR) of the prolactin receptor gene (PRLR), which encodes an anterior pituitary peptide hormone involved i..

Regulation of cotton fiber elongation by xyloglucan endotransglycosylase/hydrolase genes

Authors: M.Y. Shao, X.D. Wang, M. Ni, N. Bibi, S.N. Yuan, W. Malik, H.P. Zhang, Y.X. Liu and S.J. Hua

Ligon lintless mutant (li1li1) with super-short fibers (5-8 mm in length) and its wild type (Li1Li1) with normal fibers (30 mm in length) were used to study the function of xyloglucan endotransglycosylase/hydrolase (XTH) genes during fiber elongation in cotton. Wild-type cotton attained the fiber elongation stage earlier (5 da.. Read More»

Authors: J.T. Shu, W.J. Xu, M. Zhang, W.T. Song, Y.J. Shan, C. Song, W.Q. Zhu, X.Y. Zhang and H.F. Li

The peroxisome proliferators-activated receptor-γ coactivator-1α (PGC-1α) is a candidate gene for meat quality traits because of its prominent role in muscle fiber type switching and determination. We investigated the effects of the PGC-1α gene on chicken skeletal muscle fiber type switching and on othe.. Read More»
