The Ets Sequence From The Transforming Gene Of Avian Erythroblastosis Virus, E26, Has Unique Domains On Human Chromosomes 11 And 21: Both Loci Are Transcriptionally Active, Dennis K. Watson, Mary J. Mcwilliams-Smith, M. F. Nunn, Peter Duesberg, Stephen J. O'Brien, Takis S. Papas

Human DNA segments homologous to the ets region from the transforming gene of avian erythroblastosis virus, E26, were molecularly cloned and shown to be closely related to the viral equivalent by hybridization and partial sequence analysis. The transforming gene of E26 has a tripartite origin with the structure ∆gag [1.2 kilobases (kb) from the viral gag gene]-myb(0.9 kb from the chicken myb gene)-ets (1.6 kb from the chicken ets gene). Human ets DNA is located on two distinct human chromosomes. The human ets-1 locus on chromosome 11 encodes a single mRNA of 6.8 kb; the second locus, …
Genetic Mapping Of Endogenous Rd-114 Retroviral Sequences Of Domestic Cats, Roger H. Reeves, William G. Nash, Stephen J. O'Brien
Genetic Mapping Of Endogenous Rd-114 Retroviral Sequences Of Domestic Cats, Roger H. Reeves, William G. Nash, Stephen J. O'Brien
Biology Faculty Articles
The RD-114 family of endogenous retroviral sequences in domestic cats has been shown to consist of approximately 20 copies of genetically divergent virogenes per haploid genome. The chromosomal localization for four endogenous sequences (RDV1-4) was accomplished by correlating the occurrence of specific feline chromosomes with diagnostic viral DNA fragments in a panel of cat x rodent somatic cell hybrids. Analysis of the hybrid panel revealed that endogenous RD-114 sequences are dispersed on multiple cat chromosomes, that certain proviral segments are polymorphic with respect to the presence or absence of virus, and that a restriction fragment characteristic of inducible RD-114 resides …
Twenty-Seven Protein Polymorphisms By Two-Dimensional Electrophoresis Of Serum, Erythrocytes, And Fibroblasts In Two Pedigrees, David Goldman, Lynn R. Goldin, P. Rathnagiri, Stephen J. O'Brien, Janice A. Egeland, Carl R. Merril
Twenty-Seven Protein Polymorphisms By Two-Dimensional Electrophoresis Of Serum, Erythrocytes, And Fibroblasts In Two Pedigrees, David Goldman, Lynn R. Goldin, P. Rathnagiri, Stephen J. O'Brien, Janice A. Egeland, Carl R. Merril

Twenty-seven independent polymorphic loci were detected by two-dimensional electrophoresis (2DE) of serum, erythrocytes, and fibroblasts in two large families and analyzed for linkage to classical genetic markers. We detected seven serum, four erythrocyte, and 17 fibroblast protein loci that exhibited charge variation in these two families and in a sample of unrelated individuals. The genetic basis of protein variants was confirmed by quantitative gene-dosage dependence and by conformance to Mendelian transmission in the two families, except for four rare variants for which transmission analysis was not possible. Linkage analysis demonstrated that each of the variants represent products of independent loci, …
Variation In Population Sex Ratio And Mating Success Of Asexual Lineages Of Alsophila Pometaria (Lepidoptera: Geometridae), Lawrence G. Harshman, Douglas J. Futuyma
Variation In Population Sex Ratio And Mating Success Of Asexual Lineages Of Alsophila Pometaria (Lepidoptera: Geometridae), Lawrence G. Harshman, Douglas J. Futuyma
Lawrence G. Harshman Publications
Populations of Alsophila pometaria (Harris) are largely gynogenetic and composed of asexual females that must mate with a conspecific male to reproduce. Within this asexual contingent, there are a variety of electrophoretically defined multilocus genotypes. In this study we found that populations differ in sex ratio. We also found that there is an indication of differential mating success among asexual genotypes in a population of A. pometaria.
Male Effects On Fecundity In Drosophila Melanogaster, Ary A. Hoffman, Lawrence G. Harshman
Male Effects On Fecundity In Drosophila Melanogaster, Ary A. Hoffman, Lawrence G. Harshman
Lawrence G. Harshman Publications
Effects of male Drosophila melanogaster on female fecundity and productivity were examined, considering both females held in containers with males and females exposed to male effects not involving contact. Females were more fecund when male effects were present, and the largest increase was recorded when vials were previously conditioned by males. This effect was probably due to the growth of transmitted microorganisms, which were observed on the laying surface, as further experiments with vials conditioned by virgin females showed a similar increase in fecundity. A male-specific effect was isolated by conditioning bottles containing only agar with males and virgin females. …
The Origin And Distribution Of Clonal Diversity In Alsophila Pometaria (Lepidoptera: Geometridae), Lawrence G. Harshman, Douglas J. Futuyma
The Origin And Distribution Of Clonal Diversity In Alsophila Pometaria (Lepidoptera: Geometridae), Lawrence G. Harshman, Douglas J. Futuyma
Lawrence G. Harshman Publications
A survey of spatial and temporal variation in the frequency of electrophoretically defined genotypes in the geometrid moth Alsophila pometaria revealed a high diversity of uncommon or rare asexual genotypes and clinal distributions of two of the more common clones. There was substantial year-to-year variation in genotype frequencies in seven of eleven sites. Progeny tests have revealed that sexual reproduction is uncommon in two populations and that new asexual genotypes arise from the sexual population. The recurrent origin of asexual genotypes is likely to account for the high genetic and ecological diversity of the asexual contingent of this species’ populations, …

Seasonal Responses Of Filtration Rates To Temperature, Oxygen Availability, And Particle Concentration Of The Freshwater Clam, Musculium Partumeium (Say), Albert J. Burky, Richard B. Benjamin, Denis G. Conover, Jennifer Detrick
Seasonal Responses Of Filtration Rates To Temperature, Oxygen Availability, And Particle Concentration Of The Freshwater Clam, Musculium Partumeium (Say), Albert J. Burky, Richard B. Benjamin, Denis G. Conover, Jennifer Detrick
Biology Faculty Publications
Seasonal filtration rates of a pond population of the freshwater pisidiid clam, Musculium partumeium (Say), were assessed by measuring the clearance of 2.02 µ.m latex beads from suspension and expressed in terms of FR = a(AFDW}b where FR = filtration rate (ml H20 · hr- 1 ) , AFDW = mg ash-free dry weight of a whole clam and "a" and "b" are constants. The a-values ( = FR of a 1-mg AFDW clam} vary seasonally with the highest rates corresponding to periods of maximum growth and reproduction in the spring and fall. Changes in "b" reflect the influence of …
