We describe the development of polymerase chain reaction-based, sequence-tagged site (STS) markers for fine mapping of the barley (Hordeum vulgare) Ror1 gene required for broad-spectrum resistance to powdery mildew (Blumeria graminis f. sp. hordei). After locating Ror1 to the centromeric region of barley chromosome 1H using a combined amplified fragment length polymorphism/restriction fragment-...

the pathogenesis of bipolar i disorder (bp-i) involves immune-mediated mechanisms, especially an imbalance in pro-inflammatory/anti-inflammatory cytokines in plasma or cerebrospinal fluid. interleukin-1 (il-1) gene cluster, coding some of these pro-inflammatory cytokines, might play a role in various neuropathologies related to neuron inflammation. the aim of the present study was to investigat...

background: the heartworm disease is an infectious disease of dogs with dirofilaria immitis combined with cardiovascular and circulatory abnormalities. the heartworm disease can become a serious health risk when associated with a severe infection. in this study, a male, 8 year-old dog that died suddenly was necropsied and all tissues were examined grossly. methods: major organs including heart,...

Actinobacillus pleuropneumoniae serotype 7 strains are shown to spontaneously lose cytolytic activity with a frequency of approximately 10(-4). The phenotypic change is associated with the loss of approximately 8.5 kbp of chromosomal DNA. A genomic fragment encoding the cytolysin and its flanking sequences was cloned and characterized. Also, the corresponding truncated fragment was cloned from ...

BACKGROUND The reliability of gene expression profiling-based technologies to detect transcriptional differences representative of the original samples is affected by the quality of the extracted RNA. It strictly depends upon the technique that has been employed. Hence, the present study aimed at systematically comparing silica-gel column (SGC) and guanidine isothiocyanate (GTC) techniques of R...

Pinus radiata (Monterey pine), a tree native to coastal California and Mexico, is widely planted worldwide for timber production. A major threat to Monterey pine plantations is the fungal disease pine pitch canker, caused by Fusarium circinatum (Hypocreales). We present a novel trapping approach using filter paper in combination with a rapid molecular method to detect the presence of inoculum i...

a new strategy for construction of synthetic gene encoding human basic fibroblast growth factor comprising dna annealing-ligation and augmentation by polymerase chain reaction was introduced. the sequence of the gene and corresponding amino acid chain were modified in order to increase stability of the protein. first, 300 bp and 160 bp fragments of the gene were assembled from 18 oligonucleotid...
