Authors: J. Lin, X.C. Wang, Y.H. Chang and J.G. Fang
Accurate and reliable cultivar identification of crop species is essential to guarantee plant material identity for purposes of registration, cultivar protection and production. To facilitate identification of plant cultivars, we developed a novel strategy for efficient recording of DNA molecular fingerprints in genotyped plan.. Read More»

Verification of specific selection SNPs between broiler and layer chicken in Chinese indigenous chicken breeds
Authors: D. Lan, Y.D. Hu, Q. Zhu, D.Y. Li and Y.P. Liu
The direction of production for indigenous chicken breeds is currently unknown and this knowledge, combined with the development of chicken genome-wide association studies, led us to investigate differences in specific loci between broiler and layer chicken using bioinformatic methods. In addition, we analyzed the distribution of these seven identified lo.. Read More»

Genetic diversity of Brazilian and introduced olive germplasms based on microsatellite markers
Authors: A.D.B. do Val, J.L. Ferreira, J. Vieira Neto, M. Pasqual, A.F. de Oliveira, A. Bor�©m and G.M.A. Can�§ado
Olive trees have been grown since the beginning of civilization, and the consumption of olives and olive products is increasing worldwide, due to their health benefits and organoleptic qualities. To meet the growing market for olives, commercial cultivation of this species is expanding from traditional areas to new regions. Al.. Read More»

Genetic variation in a wild population of the �sleep� passion fruit (Passiflora setacea) based on molecular markers
Authors: C.B.M. Cerqueira-Silva, E.S.L. Santos, L.D.H.C.S. Concei�§�£o, C.B. Cardoso-Silva, A.S. Pereira, A.C. Oliveira and R.X. Corr�ªa
Little is known about the molecular genetic diversity of most Passiflora species. We used RAPD markers to evaluate the genetic diversity of 24 genotypes of the ‘sleep’ passion fruit (Passiflora setacea). Twelve primers generated 95 markers, 88% of which were polymorphic. The genetic distance estimated by the comple.. Read More»

Polymorphisms in the leptin gene promoter in Brazilian beef herds
Authors: R.C. Guimar�£es, J.S.N. Azevedo, S.C. Corr�ªa, J.E.G. Campelo, E.M. Barbosa, E.C. Gon�§alves and E. Silva Filho
Brazil is the world’s largest producer of beef cattle; however, the quality of its herds needs to be improved. The use of molecular markers as auxiliary tools in selecting animals for reproduction with high pattern for beef production would significantly improve the quality of the final beef product in Brazil. The leptin.. Read More»

Search for methylation-sensitive amplification polymorphisms in mutant figs
Authors: M.G.F. Rodrigues, A.B.G. Martins, B.W. Bertoni, A. Figueira and S. Giuliatti
Fig (Ficus carica) breeding programs that use conventional approaches to develop new cultivars are rare, owing to limited genetic variability and the difficulty in obtaining plants via gamete fusion. Cytosine methylation in plants leads to gene repression, thereby affecting transcription without changing the DNA sequence. Previous studies using random amp.. Read More»

Comparative analysis of soybean genotype resistance to Heterodera glycines and Meloidogyne species via resistance gene analogs
Authors: P.M.H. Vieira, F.A.S. Ar�ªdes, A. Ferreira and M.F.S. Ferreira
Nematodes are important pests of soybean throughout the world and cause high yield losses. As a control strategy, the identification of resistance genes is an important aim of breeding studies. Plants possess resistance genes (R), which are responsible for the recognition of pathogens and activation of the defense system. R ge.. Read More»

Maintaining and restoring cytoplasmic male sterility systems in pepper (Capsicum annuum L.)
Authors: Y. Ma, W. Huang, J.-J. Ji, Z.-H. Gong, C.-C. Yin, S.S. Ahmed and Z.-L. Zhao
We studied the efficiency of maintaining and restoring cytoplasmic male sterility (CMS) systems in pepper (Capsicum annuum L.). An Rf-linked molecular marker was employed to analyze the interaction between 6 CMS lines (A), 5 maintainers (B), and 6 restorers (C). Sterility was maintained in the matings of lines 201A x 200B, 203A x 200B, 206A x 200B, 200A x.. Read More»

Increased relatedness among the neighboring plants from seedling to adult stages in carna�ºba wax palm
Authors: F.A. Vieira, R.F. Sousa, C.G. Fajardo and M.M. Brand�£o
The objective of this study was to assess the spatial genetic structure (SGS) at different life stages (cohorts) in a remnant population (N = 101) of Copernicia prunifera in the semiarid region of northeastern Brazil. Using seven inter-simple sequence repeat molecular markers, we were able to analyze 93 loci with 100% polymorp.. Read More»
