Molecular cloning and characterization of gene coding for �³-tocopherol methyltransferase from lettuce (Lactuca sativa)
Authors: Y.L. Tang, W.W. Ren, L. Zhang and K.X. Tang
γ-tocopherol methyltransferase is an important rate-limiting enzyme involved in tocopherol biosynthesis. The full-length cDNA encoding γ-tocopherol methyltransferase (designated as LsTMT) was cloned from Lactuca sativa for the first time by rapid amplification of cDNA ends and characterized by means of quantitative..

Structural model and ligand interactions of the Xanthomonas axonopodis pv. citri oligopeptide-binding protein
Authors: A. Moutran, A. Balan, L.C.S. Ferreira, A. Giorgetti, A. Tramontano and R.C.C. Ferreira
The oligopeptide-binding protein, OppA, ushers oligopeptide substrates to the membrane-associated oligopeptide permease (Opp), a multi-component ABC-type transporter involved in the uptake of oligopeptides by several bacterial species. In the present study, we report a structural model and an oligopeptide docking analysis of t.. Read More»

Cassava genetic resources and their utilization for breeding of the crop
Authors: Nagib M.A. Nassar
Wild cassava relatives are perennials and vary in growth pattern from nearly acaulescent subshrubs to small trees. They have been used as a source of useful characters such as high protein content, apomixis, resistance to mealybug and mosaic disease, and tolerance to drought. Indigenous clones are a potential source of β-.. Read More»

Analysis of genetic relationships and identification of lily cultivars based on inter-simple sequence repeat markers
Authors: G.F. Cui*, L.F. Wu*, X.N. Wang, W.J. Jia, Q. Duan, L.L. Ma, Y.L. Jiang and J.H. Wang
Inter-simple sequence repeat (ISSR) markers were used to discriminate 62 lily cultivars of 5 hybrid series. Eight ISSR primers generated 104 bands in total, which all showed 100% polymorphism, and an average of 13 bands were amplified by each primer. Two software packages, POPGENE 1.32 and NTSYSpc 2.1, were used to analyze the.. Read More»

Optimization of chloroplast microsatellite PCR conditions and primer screening for endangered Rheum officinale, Rheum palmatum, and Rheum tanguticum
Authors: Y. Zhou, Z.J. Guo, L. Han, Y. Li and X.M. Wang
Chloroplast microsatellite primers were developed in order to provide more population genetic information of endangered Rheum officinale, R. palmatum, and R. tanguticum for conservation. The dried roots and rhizomes of these plants are important in traditional Chinese medicine. The results showed that the optimum concentrations .. Read More»

Genetic diversity of Qatari date palm using SSR markers
Authors: K. Elmeer and I. Mattat
The genetic diversity in the date palm germplasm of 59 female accessions representing 12 cultivars from different locations in Qatar was investigated using 14 loci of simple-sequence repeat (SSR) primers. A total of 94 alleles, with a mean of 6.7 alleles per locus, were scored. The number of alleles per locus varied from 3 (primer mPdCIR090) to 11.. Read More»

Genetic diversity, population structure, and association mapping of agronomic traits in waxy and normal maize inbred lines
Authors: K.J. Sa, J.Y. Park, S.H. Choi, B.W. Kim, K.J. Park and J.K. Lee
Understanding genetic diversity, population structure, and linkage disequilibrium is a prerequisite for the association mapping of complex traits in a target population. In this study, the genetic diversity and population structure of 40 waxy and 40 normal inbred maize lines were investigated using 10 morphological traits and 200 simple sequence repeat (S..

Mapping quantitative trait loci for sheath blight disease resistance in Yangdao 4 rice
Authors: Z.H. Wen, Y.X. Zeng, Z.J. Ji and C.D. Yang
Rice sheath blight (ShB), which is caused by Rhizoctonia solani, has become the most serious rice disease in China. Yangdao 4, a cultivar with partial resistance to ShB, was crossed with Lemont, a susceptible cultivar, to develop mapping populations that were used to analyze quantitative trait loci (QTL) that confer resistance to ShB. QTL analysis were pe.. Read More»

Molecular characterization of Ephedra species found in Pakistan
Authors: S. Ghafoor, M.M. Shah, H. Ahmad, Z.A. Swati, S.H. Shah, A. Pervez and U. Farooq
Ephedra, also known as “ma huang”, is a dioecious, drought- and frost-resistant, perennial, evergreen shrub with compelling medicinal value. The genus is represented by 42 species around the world, 9 of which were provisionally reported from Pakistan. Species of the genus have a controversial taxonomy due to their .. Read More»

A novel random amplified polymorphic DNA-based strategy for genetic diversity analysis and identification of tomatoes
Authors: X. Cao, Z. Wu, R. Zhou, F.L. Jiang and Z.E. Yang
Cultivar identification diagrams (CIDs) provide a rapid and efficient approach for identifying cultivars based on random amplified polymorphic DNA (RAPD) markers. In this paper, 64 tomato cultivars were identified using a CID. Using RAPD profiles, clustering analysis was performed to analyze genetic diversity. The results showed that 8 RAPD primers could ..
