Quantitative trait locus analysis of leaf morphological characters, yield-related traits, and secondary metabolite contents in Eucommia ulmoides
Authors: Y. Li, J.K. Wei, Z.Q. Li, A.N. Lei and M.H. Liu
Eucommia ulmoides is cultivated for the production of eucommia rubber and Chinese herbal drugs. Molecular breeding methods, such as marker-assisted selection (MAS), have the potential to improve the efficiency of E. ulmoides breeding. Quantitative trait locus (QTL) analysis was applied to identify marker-trait associations for E. ulmoides using an F1 mapp.. Read More»

A minimal DNA cassette as a vector for genetic transformation of soybean (Glycine max)
Authors: G.R. Vianna, F.J.L. Arag�£o and E.L. Rech
Currently, the market demands products committed to protecting human health and the environment, known as clean products. We developed a protocol using DNA fragments containing only the gene sequence of interest, to replace the circular vectors containing genes for antibiotic resistance and other undesirable sequences, for obt..

Genetic diversity and differentiation in Prunus species (Rosaceae) using chloroplast and mitochondrial DNA CAPS markers
Authors: S. Ben Mustapha,H. Ben Tamarzizt,G. Baraket,D. Abdallah and A. Salhi Hannachi
Chloroplast (cpDNA) and mitochondrial DNA (mtDNA) were analyzed to establish genetic relationships among Tunisian plum cultivars using the polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) technique. Two mtDNA regions (nad 1 b/c and nad 4 1/2) and a cpDNA region (trnL-trnF) were amplified and digested using restriction enzymes... Read More»

Chromosome stickiness impairs meiosis and influences reproductive success in Panicum maximum (Poaceae) hybrid plants
Authors: C. Pessim,M.S. Pagliarini,N. Silva and L. Jank
Chromosome stickiness has been studied in several species of higher plants and is characterized by sticky clumps of chromatin resulting in sterility. Chromosome stickiness was recorded in Panicum maximum hybrid plants that were cultivated in the field. In the meiocytes affected, chromosomes clumped into amorphous masses that did not orient themselves on t.. Read More»

DNA variation and polymorphism in Tunisian plum species (Prunus spp): contribution of flow cytometry and molecular markers
Authors: H. Ben Tamarzizt, D. Walker, S. Ben Mustapha, D. Abdallah, G. Baraket, A. Salhi Hannachi and S. Zehdi Azzouzi
Plums (Prunus spp) are among the most important stone fruit crops in the world. European (Prunus domestica) and Japanese (Prunus salicina) plums are characterized by different levels of ploidy. Because genetic variability is the prerequisite for any plant-breeding program, we aimed to establish the taxonomic status of Tunisian plums and study their geneti.. Read More»

Agro-ecological variations of sheath rot disease of rice caused by Sarocladium oryzae and DNA fingerprinting of the pathogen�s population structure
Authors: M. Tajul Islam Chowdhury, M. Salim Mian, M.A. Taher Mia, M.Y. Rafii and M.A. Latif
To examine the impact of regional and seasonal variations on the incidence and severity of sheath rot, a major seed-borne disease of rice caused by Sarocladium oryzae, data on incidence and severity were collected from 27 selected fields in the Gazipur, Rangpur, Bogra, Chittagong, Comilla, Gopalgonj, Jessore, Manikgonj, and Bhola districts of Bangladesh i..

Cloning of superoxide dismutase from post-harvest Hami melon and quantitative expression analysis before and after disease
Authors: C.H. Shan, F.X. Tang, W. Chen and W.R. Ma
Primers were designed according to the Cu/Zn-SOD gene sequences of cloned Cucurbits plants (cucumbers and watermelons) available in NCBI. Total RNA from Hami melon pulp was used as a template. Following RT-PCR amplification, a 403-bp fragment of the Hami melon Cu/Zn-SOD gene was obtained. According to alignment in BLAST and phylogenetic tree analysis, the.. Read More»

Genetic diversity and structure in natural populations of Maytenus truncata Reiss, 1861, a medicinal plant vulnerable to extractivism in Bahia State, Brazil
Authors: R.R. Simplicio, A.M. Waldschmidt, M.B. Amorim, B.S. Almeida and D.G. Pereira
Maytenus truncata (Celastraceae) is a plant species widely used in the treatment of ulcers and tumors. Despite the intensive harvest of native specimens in the State of Bahia, northeastern Brazil, there is no information about the genetic variability or structure of this species. Therefore, the goal of this study was to estimate the genetic diversity and .. Read More»

Genetic relationships among wild pomegranate (Punica granatum genotypes from Coruh Valley in Turkey
Authors: S. Ercisli, J. Gadze, G. Agar, N. Yildirim and Y. Hizarci
The pomegranate has been used traditionally in Coruh Valley in Turkey for a long time; fruits are harvested from wild, semi-domesticated and cultivated trees. In the valley, it occurs in general along with olive trees. We sampled 23 wild-grown pomegranate genotypes sampled from different parts of Coruh Valley and compared them.. Read More»

Genetic variability in agronomic traits of a germplasm collection of hulless barley
Authors: X.Q. Zeng
Germplasm collections represent an important genetic source for crop improvements. In this study, 220 accessions of hulless barley were collected worldwide and their genetic diversity was investigated. Sixteen agronomic traits, including yield and yield components, grain morphology, leaf size, plant height, and lodging resistance, were assessed under fiel.. Read More»
