A primary male autosomal linkage map of the domestic horse (Equus caballus) has been developed by segregation analysis of 140 genetic markers within eight half-sib families. The family material comprised four Standardbred trotters and four Icelandic horses, with a total of 263 offspring. The marker set included 121 microsatellite markers, eight protein polymorphisms, five RFLPs, three blood gro...

The red flour beetle (Tribolium castaneum) is a major pest of stored grain and grain products and a popular model species for a variety of ecological, evolutionary, and developmental biology studies. Development of a linkage map based on reproducible and highly polymorphic molecular markers would greatly facilitate research in these disciplines. We have developed a genetic linkage map using 269...

A cultivated oat linkage map was developed using a recombinant inbred population of 136 F6:7 lines from the cross 'Ogle' x 'TAM O-301'. A total of 441 marker loci, including 355 restriction fragment length polymorphism (RFLP) markers, 40 amplified fragment length polymorphisms (AFLPs), 22 random amplified polymorphic DNAs (RAPDs), 7 sequence-tagged sites (STSs), 1 simple sequence repeat (SSR), ...

Transplantation of 5 x 10(5) DBA/2 (H-2(d)) bone marrow cells into irradiated B10 and 129-strain mice (both H-2(b)) resulted in graft failure in the first recipient strain and in graft take in the second. Transplantation of B10 (H-2(b)) cells into irradiated B10.BR and C3H mice (both H-2(k)) also resulted in failure in the congenic B10.BR recipients and take in the C3H mice. Resistance and susc...

The first aneuploid strains of Dictyostelium discoideum have been unambiguously characterized, using cytological and genetic analysis. Three independently isolated, but genetically similar, fragment chromosomes have been observed in segregants from diploids formed between haploid strains derived from the NC4 and V12 isolates of D. discoideum. Once generated, the fragment chromosomes, all of whi...

Palmitoylation is a lipid modification of proteins with the covalent attachment of a palmitoyl group to a cysteine residue through a thioester linkage. Direction detection of palmitoylation is challenging because the thioester linkage is labile and palmitoyl group losses could occur during sample preparation if care is not taken. In addition, palmitoyl group dramatically increases the hydrophob...

cpc-1 is the locus specifying what is believed to be the major trans-activating transcription factor that regulates expression of amino acid biosynthetic genes subject to cross-pathway control in Neurospora crassa. Mutants altered at this locus are incapable of the global increase in gene expression normally seen in response to amino acid starvation. Using polymerase chain reaction methodology ...

The so called soluble specific substances of the three fixed types of Pneumococcus appear identical with three chemically distinct, serologically type specific polysaccharides produced by these organisms during growth in culture media (1). The immunological significance and the chemical nature of these bacterial carbohydrates have been discussed in detail in earlier publications from this labor...

background: familial hypertrophic cardiomyopathy (hcm) is caused by mutations in genes encoding cardiac sarcomere proteins. nowadays genetic testing of hcm plays an important role in clinical practice by contributing to the diagnosis, prognosis, and screening of high-risk individuals. the aim of this study was developing a reliable testing strategy for hcm based on linkage analysis and appropri...
