    Notes: Abstract  Fat facets is a Drosophila deubiquitinating enzyme required for eye development and early embryogenesis. Genetic evidence suggests that Fat facets deubiquitinates and thereby prevents the proteasomal degradation of specific substrates. The Drosophila Liquid facets protein is implicated as the critical substrate of Fat facets in the eye. A mouse homolog of Fat facets, called Fam, has been identified. The results of biochemical experiments implicate two different proteins, Af-6 and β-catenin, as substrates for Fam. Here, the functional relationship between Fat facets and Fam is explored. We show that Fam can substitute for Fat facets in all of its essential functions in Drosophila. In addition, we tested the hypothesis that Canoe and Armadillo, the Drosophila homologs of Af-6 and β-catenin, respectively, are important substrates for Fat facets in the Drosophila eye. We found no genetic evidence to support a role for either Canoe or Armadillo in the essential Fat facets pathways in Drosophila eye development. The significance of these results is discussed in light of the biochemical experiments that suggest that Af-6 and β-catenin are substrates of Fam.

    Notes: Abstract  Stripe rust, leaf rust, and Barley Yellow Dwarf Virus (BYDV) are important diseases of barley (Hordeum vulgare L). Using 94 doubled-haploid lines (DH) from the cross of Shyri x Galena, multiple disease phenotype datasets, and a 99-marker linkage map, we determined the number, genome location, and effects of genes conferring resistance to these diseases. We also mapped Resistance Gene Analog Polymorphism (RGAP) loci, based on degenerate motifs of cloned disease resistance genes, in the same population. Leaf rust resistance was determined by a single gene on chromosome 1 (7H). QTLs on chromosomes 2 (2H), 3 (3H), 5 (1H), and 6 (6H) were the principal determinants of resistance to stripe rust. Two- locus QTL interactions were significant determinants of resistance to this disease. Resistance to the MAV and PAV serotypes of BYDV was determined by coincident QTLs on chromosomes 1 (7H), 4 (4H), and 5 (1H). QTL interactions were not significant for BYDV resistance. The associations of molecular markers with qualitative and quantitative disease resistance loci will be a useful information for marker-assisted selection.
