    Notes: Most genes for resistance to barley leaf scald map either to the Rrs1 locus on the long arm of chromosome 3H, or the Rrs2 locus on the short arm of chromosome 7H. Other loci containing scald resistance genes have previously been identified using lines derived from wild barley, Hordeum vulgare ssp. spontaneum. A single dominant gene conditioning resistance to scald was identified in a third backcross (BC3F3) line derived from an Israeli accession of wild barley. The resistance gene is linked to three microsatellite markers that map to the long arm of chromosome 7H; the closest of these loci, HVM49, maps 11.5 cM from the resistance gene. As no other scald resistance genes have been mapped to this chromosome arm, it is considered to be a novel scald resistance locus. As the Acp2 isozyme locus is linked to this scald resistance locus, at 17.7 cM, Acp2 is assigned to chromosome 7H. Molecular markers linked to the novel scald resistance gene, designated Rrs15, can be used in breeding for scald resistance.

    Notes: Isoelectric focusing (IEF) and immunoblotting were used to detect genetic variants of malt endopeptidase (MEP1), an enzyme related to malting quality in barley and coded by the CepB locus on barley chromosome 3 (= 3H). A variant was found in a Turkish accession of wild barley (Hordeum vulgare ssp. spontaneum). The self progeny of a hybrid between this accession and the barley cultivar ‘Clipper’ were analyzed for recombination between the CepB locus and other isozyme loci. The estimates of recombination linked the CepB locus to an NADH diaphorase locus (Ndh2), which in turn was linked to the seedling esterase complex (Est1, Est2, and Est4) situated near the distal end of the long arm of chromosome 3. The Ndh2 locus was independent of two other NADH dehydrogenase loci (Ndh3, Ndh5) which were mapped on barley chromosome 5 (= 1H) in relation to the three hordein loci (Hor1, Hor2, and Hor3).

    Genes for scald resistance from wild barley (Hordeum vulgare ssp spontaneum) and their linkage to isozyme markers (1991)

    Notes: Summary Accessions of Hordeum vulgare ssp. spontaneum, the wild progenitor of barley, collected in Israel (70), Iran (15) and Turkey (6) were screened for seedling response to four isolates of Rhynchosporium secalis, the pathogen causing leaf scald in barley. Resistance was very common in the collection (77%) particularly among accessions from the more mesic sites (90%). The genetics of this resistance were investigated in fifteen backcross (BC3) lines that contained an isozyme variant from H.v. ssp. spontaneum in a H.v. ssp. vulgare (cv. Clipper) background and were resistant to scald. Segregation in the BC3F2 families conformed with a single dominant resistance gene in 9 of the 15 lines. Scald resistance and the isozyme marker were closely linked in three of the BC3-lines, loosely linked in four and unlinked in the remaining eight. Scald resistance genes were identified on barley chromosomes 1, 3, 4 and 6. Crosses between several of the scald resistant BC-lines together with the linkage data indicated that at least five genetically independent resistances are available for combining together for deployment in barley. The linkage of scald resistance in several BC3-lines to the isozyme locus Acp2 is of special interest as this locus is highly polymorphic in wild barley.

    Does progesterone cause an irritable bladder? (1993)

    Notes: Abstract Nine women with primary ovarian failure, who were having their artificial menstrual cycles manipulated with physiological levels of estrogen and high doses of progesterone, were entered into the study. They filled in urinary symptom questionnaires and had urodynamic investigations in the two phases of treatment: estrogen and progesterone, and estrogen alone. The number of voids per 24 hours was significantly greater in the progesterone phase, as was the end filling pressure on cystometry. This is the first report in the literature of the effects of high-dose progesterone on the lower urinary tract.
