Phylogenetic relationships among Saccharum clones in Pakistan revealed by RAPD markers

Authors: S. Nawaz, F.A. Khan, S. Tabasum, M. Zakria, A. Saeed and M.Z. Iqbal

Forty sugarcane genotypes (clones), including elite lines, commercial cultivars of Saccharum officinarum and S. barberi clones, were fingerprinted with 30 RAPD markers, using a PCR-based marker assay. The genetic distance for RAPD data was determined according to Nei, and relationships between accessions were graphed in a dend.. Read More»

Selectional versus mutational mechanism underlying genomic features of bacterial strand asymmetry: a case study in Clostridium acetobutylicum

Authors: H.-L. Zhao, Z.-K. Xia, Z.-G. Hua and W. Wei

Strand biases are widespread in bacterial genomes. In this review, we discuss 5 types of bias, including gene orientation, the number of open reading frames, nucleotide composition, substitution rate, and gene length, between leading and lagging strands during replication. For each type of strand bias, related studies were summarized and Clostridium aceto.. Read More»

Complete mitochondrial genome of a natural triploid crucian carp mutant, Carassius auratus var. pingxiangnensis, and phylogenetic analysis of different ploidies in crucian carp

Authors: J.Q. Sheng, J.H. Wang, S.H. He, L.G. Zeng, K. Peng and Y.J. Hong

Carassius auratus var. pingxiangnensis is a natural triploid crucian carp mutant. In order to understand its placement and genetic background at the gene level, the characteristics of mitochondrial DNA sequences and phylogenetic relationship were examined. The results showed that the mitochondrial DNA is a ci.. Read More»

Genetic polymorphisms of cytochrome P450 enzymes 2C9 and 2C19 in a healthy Mongolian population in China

Authors: Z.F. Yang, H.W. Cui, T. Hasi, S.Q. Jia, M.L. Gong and X.L. Su

We examined the distribution of major allelic variants of CYP2C9 and CYP2C19 in the Mongolian population of China and compared it with that of other populations. The polymorphisms of CYP2C9 (including the CYP2C9*1, CYP2C9*2 and CYP2C9*3 alleles) and CYP2C19 (including the CYP2C19*1, CYP2C19*2 and CYP2C19*3 alleles) were analyz.. Read More»

Remarkably low genetic variation but high population differentiation in the climbing perch, Anabas testudineus (Anabantidae), based on the mtDNA control region

Authors: A.F.J. Jamsari, Z.A. Muchlisin, M. Musri and M.N. Siti Azizah

Anabas testudineus (Anabantidae) is an important food fish in Southeast Asia. We analyzed the mitochondrial DNA control region sequence data to evaluate the genetic variability and population structure of this species. Sixty specimens were collected from four populations in Sumatra and two populations in Peninsular Malaysia. W.. Read More»

Variation characteristics of the nitrate reductase gene of key inbred maize lines and derived lines in China

Authors: J.J. Zhang, X.Q. Zhang, Y.H. Liu, H.M. Liu, Y.B. Wang, M.L. Tian and Y.B. Huang

Key inbred lines have played a fundamental role in maize genetics and breeding. Research on variation characteristics of key genes from key inbred lines and from derived lines is important for early identification and evaluation of inbred maize lines. The nitrate reductase (NR) gene, which plays a central role in nitrate acqui.. Read More»

Development of novel chloroplast microsatellite markers for Ginkgo biloba

Authors: M. Xu, L.A. Xu, F.L. Cao, H.J. Zhang and F.X. Yu

Ginkgo biloba is considered to be a living fossil that can be used to understand the ancient evolutionary history of gymnosperms, but little attention has been given to the study of its population genetics, molecular phylogeography, and genetic resources assessment. Chloroplast simple sequence repeat (cpSSR) markers are powerful tools for genetic studies .. Read More»

Genetic diversity of the endemic flat-needle pine Pinus krempfii (Pinaceae) from Vietnam revealed by SSR markers

Authors: D.T. Phong, T.T. Lieu, V.T.T. Hien and N.T. Hiep

Pinus krempfii Lecomte (Pinaceae) is an endemic tree to Vietnam with restricted habitats at higher altitudes in the highlands. In this study, genetic variation of four populations of P. krempfii was assessed using 17 microsatellite markers (single sequence repeats). Of these 17 markers, eight were polymorphic, and among the 42 putative alleles amplified, .. Read More»

Authors: W.F. Molina, D.E.O. Alves, W.C. Ara�ºjo, P.A. Martinez, M.F.M. Silva and G.W.W.F. Costa

Inoculation with bacterial or fungal antigens that stimulate cell proliferation has been widely used to obtain metaphases for cytogenetic studies of fish. We evaluated the potential of new pharmaceutical compounds as mitogenic agents in fish, testing the efficacy of Aminovac® (mixed antigens and epsilon-acetamidocaproic ac.. Read More»
