PS2 integrin requirements in Drosophila embryo and wing morphogenesis
Article Abstract:
The construction and characterization of new Drosophila inflated (if) gene mutations were described. The spatial and temporal requirements for PS2 integrin during wing morphogenesis were also studied. Lower alpha(sub PS2) amounts were detected in embryos hemizygous for either if(super A7) or if(super B2). It was concluded that the lethal if mutations have lost or retained only a small amount of wild-type alpha(sub P52) function. Regarding wing morphogenesis, only ventral wing surface cells were found to require if+ function. Integrin function was found to be necessary from the onset of metamorphosis up to the final one or two days of wing development.

Association between rDNA alleles and quantitative traits in doubled haploid populations of barley
Article Abstract:
The associations between the barley rDNA genes at the Nor-H3 locus and other quantitative traits of agronomic importance were studied using doubled haploid populations. The results showed that the Nor-H3 locus is associated with variations in yield, thousand corn weight, water sensitivity and milling energy requirement of grain. Among these traits, the milling energy requirement was consistently associated with the Nor-H3 alleles. This indicates that this locus is a good marker for the indirect selection of endosperm texture in barley.

Characterization of mutant alleles of myospheroid, the gene encoding the beta subunit of the Drosophila PS integrins
Article Abstract:
The beta subunit of Drosophila melanogaster PS integrins is encoded by myospheroid (mys) of which there are nine mutant alleles. These alleles were characterized using southern and immunoblot analyses as well as immunofluorescence and genetic studies. Results indicate that at least one mutant allele retains activity while another acts as a complementation antimorph. Temperature-sensitive mutants cannot completely eradicate gene activity and at least two complement each other.
