Association of single nucleotide polymorphisms in the bovine leptin and leptin receptor genes with growth and ultrasound carcass traits in Nellore cattle

Authors: R.C.G. da Silva J.B.S. Ferraz F.V. Meirelles J.P. Eler J.C.C. Balieiro D.C. Cucco E.C. Mattos F.M. Rezende S.L. Silva

Given the important role of leptin in metabolism, we looked for a possible association of leptin and leptin receptor polymorphisms with carcass and growth traits in Nellore cattle. We examined associations of leptin and leptin receptor SNPs with ultrasound carcass (longissimus dorsi muscle area (ribeye area), backfat thickness and rump fat thickness and grow.. Read More»

A missense mutant of the PPAR-�³gene associated with carcass and meat quality traits in Chinese cattle breeds

Authors: Y.Y. Fan G.W. Fu C.Z. Fu L.S. Zan W.Q. Tian

The peroxisome proliferator-activated receptor gamma (PPAR-Ã?³) is a key molecule in adipocyte differentitation; it transactivates multiple target genes in lipid metabolic pathways. Using PCR-SSCP and DNA sequencing, we evaluated a potential association of an SNP (72472 Gï¹¥T in exon7) of the bovine PPAR-Ã?³gene with carcass and meat quality traits in 6.. Read More»

Molecular markers in commercial Bombyx mori (Lepidoptera: Bombycidae) hybrids susceptible to multiple nucleopolyhedrovirus

Authors: L.F.C. Ribeiro D.B. Zanatta J.P. Bravo R.M.C. Brancalh�£o M.A. Fernandez

The silkworm Bombyx mori L. is particularly susceptible to virus diseases, especially B. mori nucleopolyhedrovirus (BmNPV). Disease resistance, along with high productivity, are important selection criteria for developing commercial hybrids of B. mori. We used bioassays and molecular markers linked to susceptibility/resistance.. Read More»

Single primer-based DNA amplification as a suitable and low-cost tool for assessing genetic diversity in mangrove crabs

Authors: F.B. Britto, D.S.F. Mendes, M. Ogawa, I.H.A. Cintra and F.M. Diniz

We used single primer-based DNA markers to assess genetic variability of the mangrove crab, Ucides cordatus, collected from four different localities from Pará to Santa Catarina States in Brazil (almost 5000 km distant). Five primers were chosen based on the consistency of the amplified bands and the polymorphism of eac.. Read More»

Associations between single nucleotide polymorphisms and carcass traits in Nellore cattle using high-density panels

Authors: R. Espigolan, F. Baldi, A.A. Boligon, F.R.P. Souza, G.A. Fernandes J�ºnior, D.G.M. Gordo, G.C. Venturini, G.M.F. de Camargo, F.L.B. Feitosa, D.A. Garcia, H. Tonhati, L.A.L. Chardulo, H.N. Oliveira and L.G. Albuquerque

The objective of this study was to evaluate associations between single nucleotide polymorphism (SNP) markers and carcass traits measured postmortem in Nellore cattle. Records of loin eye area (LEA) and backfat thickness (BF) from 740 males and records of hot carcass weight (HCW) from 726 males were analyzed. All of the animals were genotyped using the Bo..

Evaluation of genetic diversity in Piper spp using RAPD and SRAP markers

Authors: Y. Jiang and J.-P. Liu

Random amplified polymorphic DNA (RAPD) and sequence-related amplified polymorphism (SRAP) analysis were applied to 74 individual plants of Piper spp in Hainan Island. The results showed that the SRAP technique may be more informative and more efficient and effective for studying genetic diversity of Piper spp than the RAPD te.. Read More»

Assessment of genetic diversity and variation of Robinia pseudoacacia seeds induced by short-term spaceflight based on two molecular marker systems and morphological traits

Authors: C.Q. Yuan Y.F. Li P. Sun Y.H. Sun G.J. Zhang M.S. Yang Y.Y. Zhang Y. Li L. Wang

The black locust (Robinia pseudoacacia) is a forest legume that is highly valued as a honey plant and for its wood. We explored the effect of short-term spaceflight on development of R. pseudoacacia seedlings derived from seeds that endured a 15-day flight; the genetic diversity and variation of plants sampled from space-mutagenized seeds were compared to pl..

Evaluation of genetic variability in in vitro sodium azide-induced Dendrobium �Earsakul� mutants

Authors: A. Wannajindaporn, O. Poolsawat, W. Chaowiset and P.A. Tantasawat

In vitro mutagenesis of Dendrobium ‘Earsakul’ was carried out by incubating the protocorm-like bodies in 0-5 mM sodium azide for 1 h. Twenty-eight putative mutants were evaluated for genetic variability compared to untreated control plants using inter-simple sequence repeat (ISSR) analysis. Polymo.. Read More»

The present study was undertaken to detect and map the quantitative trait loci (QTL) related to soybean oil content. We used 244 progenies derived from a bi-parental cross of the Lineage 69 (from Universidade Estadual Paulista “Júlio de Mesquita Filho”/Faculdade de Ciências Agrárias e Veterinárias - Breeding Program)..
