A wheat cultivar "Chinese Spring" chromosome substitution line CS-1S(l)(1B), in which the 1B chromosome was substituted by 1S(l) from Aegilops longissima, was developed and found to possess superior dough and breadmaking quality. The molecular mechanism of its super quality conformation is studied in the aspects of high molecular glutenin genes, protein accumulation patterns, glutenin polymeric...

Bone marrow cells from 37 patients with chronic myelogenous leukemia (CML), who had the characteristic Philadelphia chromosome in their leukemic cells, were examined for ABL gene rearrangement by pulsed-field gel electrophoresis. By using several probes from the ABL gene, we found that in 33 of 37 (89%) patients studied, the translocation breakpoints in ABL fell within the 175-kilobase (kb) int...

The linkage relationships in wild emmer wheat, Triticum dicoccoides , between nine enzymatic loci (Mdh-1, Ipo, beta-Glu, Pept-1, Pept-3, Est-5, Est-1, 6Pgdh-2 and Hk) and a coleoptile pigment locus (Rc) were investigated. Chromosome locations of genes were inferred from analysis of ditelocentric lines of Triticum aestivum, cultivar Chinese Spring. The loci Mdh-B1 and Hk are linked (lambda = 0.1...

Although there are some obvious differences between the X chromosome and the autosomes—such as the X chromosome being present in only one copy in males— the two types of chromosome are remarkably similar in their cytological appearance and gene density [1]. Genomic and transcriptomic studies of Drosophila, however, have revealed two major differences in gene content between the X chromosome and...

Morphine antinociception has been shown to be influenced significantly by genetic factors, now beginning to be identified in mice. A recent quantitative trait locus analysis revealed a significant statistical association between morphine antinociceptive magnitude and a region of mouse chromosome 9. This region contains the Htr1b gene, which encodes the 5-hydroxytryptamine (serotonin)-1B (5-HT(1...

Epidemic Canadian methicillin-resistant Staphylococcus aureus strain 1 (CMRSA-1) comprises related subtypes that differ in phenotype and prevalence, with subtypes 1A, 1B, and 1D representing 1%, 71%, and 18%, respectively, of total CMRSA-1 isolates. The predominant CMRSA-1B subtype possesses a variant of the staphylococcal cassette chromosome mec, harboring pls, which encodes plasmin-sensitive ...

Condemning a laissez faire approach to English Language Teaching (ELT), English as a Foreign Language (EFL) teacher trainers unanimously agree that the building blocks of teachers’ teaching framework are profoundly influenced by conducting research. Focusing on quantitative research, this study endeavored to scrutinize the impact of the Critical Appraisal of Published Research (CAPR) in undergr...
