Impact of MTHFR polymorphisms on methylation of MGMT in glioma patients from Northeast China with different folate levels
Authors: N. Liu1, J. Jiang1, Y.J. Song2, S.G. Zhao3, Z.G. Tong4, H.S. Song1, H. Wu1, J.Y. Zhu1, Y.H. Gu1, Y. Sun1, W. Hua1 and J.P. Qi1
Hypomethylation of the O6-methylguanine-DNA-methyltransferase (MGMT) promoter in glioma cells has been associated with temozolomide resistance. S-adenosylmethionine (SAM), which is produced during folate metabolism, is the main source of methyl groups during DNA methylation... Read More»

Genetic diversity and coefficient of parentage between clones and sugarcane varieties in Brazil
Authors: B.P. Brasileiro1, C.D. Marinho1, P.M.A. Costa1, L.A. Peternelli1, M.D.V. Resende2, D.E. Cursi3, H.P. Hoffmann3 and M.H.P. Barbosa4
The success of the development of new sugarcane varieties is associated with the ability to correctly select the genitor. The aim of this study was to evaluate the genetic diversity between 113 clones and sugarcane varieties using the Ward-modified location model procedure with added information about the coefficient of parentage and endogamy. In this stu.. Read More»

Simple sequence repeat-based association analysis of fruit traits in eggplant (Solanum melongena)
Authors: H.Y. Ge1, Y. Liu1, J. Zhang2, H.Q. Han1, H.Z. Li1, W.T. Shao1 and H.Y. Chen1
Association mapping based on linkage disequilibrium (LD) provides a promising tool to identify quantitative trait loci (QTLs) in plant resources. A total of 141 eggplant (Solanum melongena L.) accessions were selected to detect simple sequence repeat (SSR) markers associated with nine fruit traits. Population structure analysis was performed with 105 SSR .. Read More»

Comparison of period-3 correlation amplitudes in genomic DNA sequences
Authors: J.C.O. Guerra1, P. Licinio2 and P.C.P. Andrade1
Period-3 oscillations in genome composition can be detected through correlation functions. Since these oscillations are closely related to the genetic code structure, we developed methods for quantitative comparison of genomic and exonic oscillation amplitudes and decay. In contrast to genomic correlations, exonic period-3 oscillation amplitudes are persi.. Read More»

Role of MshQ in MSHA pili biosynthesis and biofilm formation of Aeromonas hydrophila
Authors: Y.X. Qin1,2, Q.P. Yan1,2 , X.X. Mao1,2, Z. Chen1,2 and Y.Q. Su3
Biofilm formation of pathogen bacterium is currently one of the most widely studied topics; however, little is known regarding pathogen bacteria biofi lms in aquaculture. Aeromonas hydrophila is a representative species of the genus Aeromonas, which has been recognized as a common pathogen, is associated with many diseases in aquatic animals, and causes s.. Read More»

Molecular characterization and tissue-specific expression of invariant chain isoform in Muscovy Duck (Cairina moschata)
Authors: S.J. Liu1,2, F.F. Chen2, C. Wu2, Q.S. Ni2 and W.Y. Yu2
Invariant chain (Ii) isoform, through its thyroglobulin-like (Tg) domain, inhibits cysteine proteases during antigen presentation in vertebrates. In birds, the Ii of Muscovy Duck (MDIi) has 2 forms: MDIi-1 and MDIi-2 (MDIi isoform). To understand the genetic information and expression characteristics of MDIi-2, polymerase chain reaction, and bioinformatic.. Read More»

Mutational analysis of AXIN2, MSX1, and PAX9 in two Mexican oligodontia families
Authors: Y.D. Mu1,2, Z. Xu1, C.I. Contreras1, J.S. McDaniel1, K.J. Donly1 and S. Chen1
The genes for axin inhibition protein 2 (AXIN2), msh homeobox 1 (MSX1), and paired box gene 9 (PAX9) are involved in tooth root formation and tooth development. Mutations of the AXIN2, MSX1, and PAX9 genes are associated with non-syndromic oligodontia. In this study, we investigated phenotype and AXIN2, MSX1, and PAX9 gene variations in two Mexican famili..

Selfing confirmation in sugarcane by using simple sequence repeat markers: an individual reciprocal recurrent selection scheme
Authors:
Superior inbred clones selected in S1 families can integrate an individual reciprocal recurrent selection program in sugarcane by eliminating the genetic load of the population and exploring superior hybrid combinations. Molecular markers can be used for reliable identification of the true selfing-derived clones in these S1 populations. The objective of t.. Read More»

Genetic variability in accessions of the acerola germplasm bank of Universidade Federal Rural de Pernambuco, Brazil
Authors: R.M. Moraes Filho1, L.S.S. Martins2, R.S. Musser3, A.V.V. Montarroyos3 and E.F. Silva2
Brazil is the world’s largest producer of acerola, Malpighia emarginata (Malpighiaceae); the Northeast is responsible for 60% of the national production. The culture of acerola in Brazil has great genetic variability; plantings have high phenotypic diversity and are not very productive, often originating from propagation by seed. We evaluated the ge..

Evaluation of genetic diversity in Pampus argenteus using SSR markers
Authors: Y. Qin, G. Shi and Y. Sun
In order to evaluate the germplasm resources of Pampus argenteus silver pomfret, the genetic diversity and population structure of 132 silver pomfret samples collected from the three regions (the East China Sea, the Yellow Sea and the Bohai Sea) were examined using 13 polymorphic microsatellite loci. Results indicated a high level of genetic diversity. Th.. Read More»
