Spermatogenic cyst and organ culture in Drosophila pseudoobscura
Cell and Tissue Research, 2010Spermatogenesis is a complex series of processes that involves (1) the maintenance of a renewable pool of diploid stem cells within a niche, (2) the mitotic expansion of a subpopulation of stem cells committed to the spermatogenic pathway, and (3) the differentiation of diploid cells into highly specialized, haploid spermatozoa through meiotic and post-

Fine-Scale Crossover Rate Heterogeneity in Drosophila pseudoobscura
Journal of Molecular Evolution, 2006Broad-scale differences in crossover rate across the genome have been characterized in most genomes studied. Fine-scale differences, however, have only been examined in a few taxa, such as Arabidopsis, yeast, humans, and mice. No prior studies have directly looked for fine-scale recombination rate heterogeneity in Drosophila. We produced 370 Drosophila

Analysis of a swallow homologue from Drosophila pseudoobscura
Development Genes and Evolution, 2000We analyzed a functional homologue of the swallow gene from Drosophila pseudoobscura. The swallow gene of D. melanogaster plays an essential role in localizing bicoid mRNA in oocytes, and swallow mutant embryos show anterior pattern defects that result from the lack of localization of the bicoid morphogen.

Sex-Ratio Polymorphism in Drosophila pseudoobscura
The American Naturalist, 1991I studied "sex-ratio" (SR) genotype frequencies in two populations of Drosophila pseudoobscura from southeastern Arizona: Bear Creek Canyon and Tucson. Wild-inseminated females were collected, their fecundities measured in the laboratory, and their SR genotypes inferred by cytological analysis of their progenies.

Sexual Isolation between Drosophila persimilis and Drosophila pseudoobscura
The American Naturalist, 1954Sexual isolation between the closely related species, D. persimilis and D. pseudoobscura, was studied by means of male multiple "choice" tests, female multiple "choice" tests, and multiple "choice" experiments involving the males and females of both species.

Tissue localization of esterase-5 in Drosophila pseudoobscura
Biochemical Genetics, 1983Disc gel electrophoresis of dissected adults of Drosophila pseudoobscura showed that most of the esterase-5 activity was in the head (36%) and thorax (51%), with little activity in the abdomen (13%). No activity was found in digestive tissues, reproductive tissues, or nervous tissues.
