Authors: G.M.R. Lombardi, J.A.R. Nunes, R.A.C. Parrella, D.H.L. Teixeira1, A.T. Bruzi, N.N.L. Dur�£es and T.G. Fagundes
Sweet sorghum has considerable potential for ethanol production due to its succulent stalks that contain directly fermentable sugars. Since many traits need to be considered in the selection process to breed superior cultivars for ethanol production, then correlations between the traits might be of use to help the breeder define optimal improvement strate..

Rapid determination of transgene copy number in tobacco by competitive PCR using a pair of SSR primers
Authors: K.Y. Xu, S.H. Wang, L. Xi, Q.J. Wang, C. Dong, J.Y. Zhang, S.C. Qu and Z. Zhang
We developed a straightforward, rapid, and inexpensive method to determine transgene copy number in tobacco. The plasmid (pSSRCopy) used for tobacco transformation contains a simple sequence repeat (SSR) locus, PT1199, which was partially deleted in the middle, a homogenous SSR locus in tobacco K326. A 168-bp segment of the cl.. Read More»

Association of SSR markers with contents of fatty acids in olive oil and genetic diversity analysis of an olive core collection
Authors: M. Ipek, A. Ipek, M. Seker and M.K. Gul
The purpose of this research was to characterize an olive core collection using some agronomic characters and simple sequence repeat (SSR) markers and to determine SSR markers associated with the content of fatty acids in olive oil. SSR marker analysis demonstrated the presence of a high amount of genetic variation between the olive cultivars analyzed. A UPG.. Read More»

Stripe rust resistance and dough quality of new wheat - Dasypyrum villosum translocation lines T1DL�1V#3S and T1DS�1V#3L and the location of HMW-GS genes
Authors: W.C. Zhao, X. Gao, J. Dong, Z.J. Zhao, Q.G. Chen, L.G. Chen, Y.G. Shi and X.Y. Li
The transfer of agronomically useful genes from wild wheat species into cultivated wheat is one of the most effective approaches to improvement of wheat varieties. To evaluate the transfer of genes from Dasypyrum villosum into Triticum aestivum, wheat quality and disease resistance was evaluated in two new translocation lines, T1DL•1V#3S and T1DS&bul..

Tobacco serine/threonine protein kinase gene NrSTK enhances black shank resistance
Authors: Y.-L. Gao, B.-W. Wang, Z.-L. Xu, M.-Y. Li, Z.-B. Song, W.-Z. Li and Y.-P. Li
serine/threonine protein kinase gene (NrSTK) was cloned from Nicotiana repanda based on the sequence of a previously isolated resistance gene analog (RGA). Expression of RGA was induced by challenge with the pathogen black shank. The NrSTK gene was predicted to encode a protein kinase that contained an ATP binding site at residues 41-69 and a serine/threo.. Read More»

Genome wide selection in Citrus breeding
Authors: I.B. Gois, A. Bor�©m, M. Cristofani-Yaly, M.D.V. de Resende, C.F. Azevedo, M. Bastianel, V.M. Novelli2and M.A. Machado
Genome wide selection (GWS) is essential for the genetic improvement of perennial species such as Citrus because of its ability to increase gain per unit time and to enable the efficient selection of characteristics with low heritability. This study assessed GWS efficiency in a population of Citrus and compared it with selecti.. Read More»

Genome-wide expression analysis of a rice mutant line under salt stress
Authors: K.J. Lee, S.-J. Kwon, J.E. Hwang, S.M. Han, I. Jung, J.-B. Kim, H.-I. Choi, J. Ryu and S.-Y. Kang
Salinity is a major environmental stress to plants. In this study, the ability of plants to tolerate salt was investigated by studying growth, physiological characteristics, and expression levels of genes related to the salt-stress response in the salt-tolerant rice mutant (Till-II-877), which was derived from γ-ray irra..

Molecular marker-assisted selection of the ae alleles in maize
Authors: F. Chen, S.W. Zhu, Y. Xiang, H.Y. Jiang and B.J. Cheng
The ae (amylose extender) recessive mutant alleles in maize are an important genetic resource for the development of high-amylose cultivars. On the basis of ae allele sequences (from the National Center for Biotechnology Information), the ae mutant alleles were cloned from high-amylose maize and the allelic Ae gene from common..

Breeding of Acrocomia aculeata using genetic diversity parameters and correlations to select accessions based on vegetative, phenological, and reproductive characteristics
Authors: S.M. Coser, S.Y. Motoike, T.R. Corr�ªa, T.P. Pires and M.D.V. Resende
Macaw palm (Acrocomia aculeata) is a promising species for use in biofuel production, and establishing breeding programs is important for the development of commercial plantations. The aim of the present study was to analyze genetic diversity, verify correlations between traits, estimate genetic parameters, and select differen.. Read More»

Detection of genetically modified maize in processed products, dry grains, and corn ears intended for fresh consumption in South Brazil
Authors: C.A.M. Oliveira, C.M. Kommers, F.K.M. Lehmann, A.S.K. Fonseca, N. Ikuta and V.R. Lunge
Conventional and genetically modified (GM) maize cultivars have been widely planted in Brazil to produce grains for processed food, feed, or to be consumed fresh as corn ears. This study used real-time PCR to detect GM maize in processed products and fresh commercial corn ears produced in the last two years in South Brazil. Ei.. Read More»
