Possible origins of B chromosomes in Rineloricaria pentamaculata (Loricariidae, Siluriformes) from the Paran�¡ River basin
Authors: F.E. Porto, A.L.B. Portela-Castro and I.C. Martins-Santos
We made a cytogenetic study of Rineloricaria pentamaculata from the Tauá Stream, in the Pirapó River sub-basin in Paraná State, Brazil, focused on the occurrence and origins of the B chromosomes. The diploid number varied from 2n = 56 to 2n = 59, due to the presence of 0 to 3 B microchromosomes of the acro.. Read More»

Preponderance of GC-rich sites in silver-stained nucleolus organizing regions of Rita rita (Hamilton) and Mystus gulio (Hamilton) (Bagridae, Pisces), as revealed by chromomycin A3-staining technique and scanning electron microscopic studies
Authors: Das JK and Khuda-Bukhsh AR
The karyotypes of two species of catfish, Rita rita (Hamilton) (2n = 54; 14m + 34sm + 6st; NF = 102) and Mystus gulio (Hamilton) (2n = 58; 30m + 12sm + 2st + 14t, NF = 100) were studied through Giemsa-, silver- and chromomycin A3-staining techniques. The silver-stained karyotypes in both sexes of R. rita and M. gulio revealed .. Read More»

Isolation and characterization of novel microsatellite markers from the sika deer (Cervus nippon) genome
Authors: Y.M. Li, C.Y. Bai, W.P. Niu, H. Yu, R.J. Yang, S.Q. Yan, J.Y. Zhang, M.J. Zhang and Z.H. Zhao
Microsatellite markers are widely and evenly distributed, and are highly polymorphic. Rapid and convenient detection through automated analysis means that microsatellite markers are widely used in the construction of plant and animal genetic maps, in quantitative trait loci localization, marker-assisted selection, identification of genetic relationships, ..

Transcriptomic identification of chemoreceptor genes in the red palm weevil Rhynchophorus ferrugineus
Authors: W. Yan, L. Liu, W.Q. Qin, C.X. Li and Z.Q. Peng
Olfaction is crucial for insects’ survival because it enables them to recognize various environmental information. It is primarily mediated by a large family of chemoreceptors, including olfactory receptors (ORs), gustatory receptors (GRs), and ionotropic receptors (IRs). Here, we assembled the transcriptome of the economically important pest of pal.. Read More»

Effects of acrylonitrile on the pathological morphology and apoptosis of neurons in rats
Authors: C.Z. Li, L.A. Tse, Y.L. Zhou, W. Fan, M. Li, I.T.S. Yu and T.Y. Jin
This study aimed to evaluate the effects of acrylonitrile (ACN) on neuronal morphology and apoptosis in rats. An ACN solution was administered to Wistar rats by gavage at doses of 0, 5, 10, or 20 mg/kg, 5 days a week for 13 weeks. The morphology of neurons and the presence of apoptosis was examined by light and electron micros.. Read More»

Evaluation of three different promoters driving gene expression in developing chicken embryo by using in vivo electroporation
Authors: C.Q. Yang1, X.Y. Li2, Q. Li3, S.L. Fu2, H. Li2, Z.K. Guo3, J.T. Lin2,3 and S.T. Zhao1
To investigate the variance of exogenous gene expression driven by different promoters by in vivo electroporation, 3 plasmid vectors carrying different promoters were selected, and their driving strength was compared in developing chicken embryos. The 3 promoters included: 1) the CAG promoter (containing the cytomegalovirus (C.. Read More»

Genetic parameter estimates for buffalo milk yield, milk quality and mozzarella production and Bayesian inference analysis of their relationships
Authors: R.R. Aspilcueta-Borquis, R. Di Palo, F.R. Araujo Neto, F. Baldi, G.M.F. de Camargo, L.G. de Albuquerque, L. Zicarelli and H. Tonhati
Buffalo milk has excellent physical and chemical qualities as a consequence of the high percentage of constituents. This milk property is desirable for the dairy industry because it facilitates manufacture of mozzarella cheese. We estimated genetic parameters for milk yield, milk fat and protein and their effects on mozzarella.. Read More»

Analysis of skin color change and related gene expression after crossing of Dongxiang black chicken and ISA layer
Authors: X.D. Zhang, H.H. Wang, C.X. Zhang, Q.H. Li, X.H. Chen and L.F. Lou
This study evaluated the effects of the autosomal dominant Fm gene in conjunction with the sex-linked Id gene on skin color and related gene expression. Ten Dongxiang black cocks were selected to build ten families by mating 60 individuals of ISA B-line layers. The skin color of the F1 generation was observed at different time points. At 126 days, 36 chic.. Read More»
