Structural and functional comparisons of the Drosophila virilis and Drosophila melanogaster rough genes.

ABSTRACT: We have isolated the homeobox gene rough (ro) from Drosophila virilis. Comparison of the predicted amino acid sequences of the D. melanogaster and D. virilis rough proteins reveals that domains of high conservation, including the homeodomain, are interspersed with highly diverged regions. Stretches of significant sequence conservation are also observed in the 5' promoter region and in the introns. The D. virilis rough gene rescues the rough mutant phenotype and is properly regulated when introduced into the D. melanogaster genome. Thus the rough protein as well as the cis-regulatory elements that ensure proper temporal and spatial regulation are functionally conserved between these Drosophila species.

Organizational analysis of elav gene and functional analysis of ELAV protein of Drosophila melanogaster and Drosophila virilis.

Project description:Drosophila virilis genomic DNA corresponding to the D. melanogaster embryonic lethal abnormal visual system (elav) locus was cloned. DNA sequence analysis of a 3.8-kb genomic piece allowed identification of (i) an open reading frame (ORF) with striking homology to the previously identified D. melanogaster ORF and (ii) conserved sequence elements of possible regulatory relevance within and flanking the second intron. Conceptual translation of the D. virilis ORF predicts a 519-amino-acid-long ribonucleoprotein consensus sequence-type protein. Similar to D. melanogaster ELAV protein, it contains three tandem RNA-binding domains and an alanine/glutamine-rich amino-terminal region. The sequence throughout the RNA-binding domains, comprising the carboxy-terminal 346 amino acids, shows an extraordinary 100% identity at the amino acid level, indicating a strong structural constraint for this functional domain. The amino-terminal region is 36 amino acids longer in D. virilis, and the conservation is 66%. In in vivo functional tests, the D. virilis ORF was indistinguishable from the D. melanogaster ORF. Furthermore, a D. melanogaster ORF encoding an ELAV protein with a 40-amino-acid deletion within the alanine/glutamine-rich region was also able to supply elav function in vivo. Thus, the divergence of the amino-terminal region of the ELAV protein reflects lowered functional constraint rather than species-specific functional specification.

Comparative analysis of Pdf-mediated circadian behaviors between Drosophila melanogaster and D. virilis.

Project description:A group of small ventrolateral neurons (s-LN(v)'s) are the principal pacemaker for circadian locomotor rhythmicity of Drosophila melanogaster, and the pigment-dispersing factor (Pdf) neuropeptide plays an essential role as a clock messenger within these neurons. In our comparative studies on Pdf-associated circadian rhythms, we found that daily locomotor activity patterns of D. virilis were significantly different from those of D. melanogaster. Activities of D. virilis adults were mainly restricted to the photophase under light:dark cycles and subsequently became arrhythmic or weakly rhythmic in constant conditions. Such activity patterns resemble those of Pdf(01) mutant of D. melanogaster. Intriguingly, endogenous D. virilis Pdf (DvPdf) expression was not detected in the s-LN(v)-like neurons in the adult brains, implying that the Pdf(01)-like behavioral phenotypes of D. virilis are attributed in part to the lack of DvPdf in the s-LN(v)-like neurons. Heterologous transgenic analysis showed that cis-regulatory elements of the DvPdf transgene are capable of directing their expression in all endogenous Pdf neurons including s-LN(v)'s, as well as in non-Pdf clock neurons (LN(d)'s and fifth s-LN(v)) in a D. melanogaster host. Together these findings suggest a significant difference in the regulatory mechanisms of Pdf transcription between the two species and such a difference is causally associated with species-specific establishment of daily locomotor activity patterns.

Functional dissection of Odorant binding protein genes in Drosophila melanogaster.

Project description:Most organisms rely on olfaction for survival and reproduction. The olfactory system of Drosophila melanogaster is one of the best characterized chemosensory systems and serves as a prototype for understanding insect olfaction. Olfaction in Drosophila is mediated by multigene families of odorant receptors and odorant binding proteins (OBPs). Although molecular response profiles of odorant receptors have been well documented, the contributions of OBPs to olfactory behavior remain largely unknown. Here, we used RNAi-mediated suppression of Obp gene expression and measurements of behavioral responses to 16 ecologically relevant odorants to systematically dissect the functions of 17 OBPs. We quantified the effectiveness of RNAi-mediated suppression by quantitative real-time polymerase chain reaction and used a proteomic liquid chromatography and tandem mass spectrometry procedure to show target-specific suppression of OBPs expressed in the antennae. Flies in which expression of a specific OBP is suppressed often show altered behavioral responses to more than one, but not all, odorants, in a sex-dependent manner. Similarly, responses to a specific odorant are frequently affected by suppression of expression of multiple, but not all, OBPs. These results show that OBPs are essential for mediating olfactory behavioral responses and suggest that OBP-dependent odorant recognition is combinatorial.

Evolution of gene position: chromosomal arrangement and sequence comparison of the Drosophila melanogaster and Drosophila virilis sina and Rh4 genes.

Project description:The seven in absentia (sina) gene of Drosophila encodes a nuclear protein required for normal eye development. In Drosophila melanogaster, the sina gene is located within an intron of the Rh4 opsin gene. We examine here the nucleotide sequences and chromosomal arrangements of these genes in Drosophila virilis. An interspecies comparison between D. melanogaster and D. virilis reveals that the protein-coding sequences of the sina and Rh4 genes are highly conserved, but the relative chromosomal position and structural arrangement of these genes differ between the two species. In particular, the sina and Rh4 genes are widely separated in D. virilis, and there is no intron in the Rh4 gene. Our results suggest that the Rh4 gene was translocated to another chromosomal location by a retrotransposition event.

Partial Functional Diversification of Drosophila melanogaster Septin Genes Sep2 and Sep5.

Project description:The septin family of hetero-oligomeric complex-forming proteins can be divided into subgroups, and subgroup members are interchangeable at specific positions in the septin complex. Drosophila melanogaster has five septin genes, including the two SEPT6 subgroup members Sep2 and Sep5 We previously found that Sep2 has a unique function in oogenesis, which is not performed by Sep5 Here, we find that Sep2 is uniquely required for follicle cell encapsulation of female germline cysts, and that Sep2 and Sep5 are redundant for follicle cell proliferation. The five D. melanogaster septins localize similarly in oogenesis, including as rings flanking the germline ring canals. Pnut fails to localize in Sep5; Sep2 double mutant follicle cells, indicating that septin complexes fail to form in the absence of both Sep2 and Sep5. We also find that mutations in septins enhance the mutant phenotype of bazooka, a key component in the establishment of cell polarity, suggesting a link between septin function and cell polarity. Overall, this work suggests that Sep5 has undergone partial loss of ancestral protein function, and demonstrates redundant and unique functions of septins.

Purification and enzyme stability of alcohol dehydrogenase from Drosophila simulans, Drosophila virilis and Drosophila melanogaster adhS.

Project description:Three alcohol dehydrogenases from Drosophila simulans, Drosophila virillis and Drosophila melanogaster adhS (which possesses an alloenzyme with slow electrophoretic mobility) were purified essentially to homogeneity. The purification procedure involves a new step of affinity chromatography, which efficiently lowers the amount of contaminants in the final preparation, producing a very stable enzyme. The purification procedure developed consists of a salmine sulphate precipitation, two CM-Sepharose CL-6B colume-chromatography steps, an affinity-chromatography step and a Sephacryl gel filtration. A minimum of 30-fold purification is obtained and the yield is not less than 34%. The isoelectric points and molar absorption coefficients were determined.

Multiple Genes Cause Postmating Prezygotic Reproductive Isolation in the Drosophila virilis Group.

Project description:Understanding the genetic basis of speciation is a central problem in evolutionary biology. Studies of reproductive isolation have provided several insights into the genetic causes of speciation, especially in taxa that lend themselves to detailed genetic scrutiny. Reproductive barriers have usually been divided into those that occur before zygote formation (prezygotic) and after (postzygotic), with the latter receiving a great deal of attention over several decades. Reproductive barriers that occur after mating but before zygote formation [postmating prezygotic (PMPZ)] are especially understudied at the genetic level. Here, I present a phenotypic and genetic analysis of a PMPZ reproductive barrier between two species of the Drosophila virilis group: D. americana and D. virilis This species pair shows strong PMPZ isolation, especially when D. americana males mate with D. virilis females: ∼99% of eggs laid after these heterospecific copulations are not fertilized. Previous work has shown that the paternal loci contributing to this incompatibility reside on two chromosomes, one of which (chromosome 5) likely carries multiple factors. The other (chromosome 2) is fixed for a paracentric inversion that encompasses nearly half the chromosome. Here, I present two results. First, I show that PMPZ in this species cross is largely due to defective sperm storage in heterospecific copulations. Second, using advanced intercross and backcross mapping approaches, I identify genomic regions that carry genes capable of rescuing heterospecific fertilization. I conclude that paternal incompatibility between D. americana males and D. virilis females is underlain by four or more genes on chromosomes 2 and 5.

Determination of some biochemical and structural features of alcohol dehydrogenases from Drosophila simulans and Drosophila virilis. Comparison of their properties with the Drosophila melanogaster Adhs enzyme.

Project description:The biochemical properties of the enzyme alcohol dehydrogenase of two different Drosophila species, Drosophila simulans and Drosophila virilis, were studied and compared with those of Drosophila melanogaster Adhs enzyme. All of them consist of two identical subunits of molecular weight 27800 and share significant similarities in function. The substrate specificities of these enzymes were characterized and Km(app.) and Vmax.(app.) values were calculated. All these alcohol dehydrogenases show greater affinity for secondary rather than for primary alcohols. The amino acid compositions of the three enzymes were determined, and there is a close similarity between the D. simulans and the D. melanogaster enzymes, but there are significant differences from the alcohol dehydrogenase of D. virilis. The N-terminal amino acid is blocked and the C-terminal amino acid is the same for all three alcohol dehydrogenases. The enzymes from the three species were carboxymethylated and digested with trypsin. The peptide 'maps' reveal, as expected, more homologies between the enzymes of D. simulans and D. melanogaster than with the enzyme of D. virilis.

Evolutionary Dynamics of Male Reproductive Genes in the <i>Drosophila virilis</i> Subgroup.

Project description:Postcopulatory sexual selection (PCSS) is a potent evolutionary force that can drive rapid changes of reproductive genes within species, and thus has the potential to generate reproductive incompatibilities between species. Male seminal fluid proteins (SFPs) are major players in postmating interactions, and are important targets of PCSS in males. The virilis subgroup of Drosophila exhibits strong interspecific gametic incompatibilities, and can serve as a model to study the genetic basis of PCSS and gametic isolation. However, reproductive genes in this group have not been characterized. Here we utilize short-read RNA sequencing of male reproductive organs to examine the evolutionary dynamics of reproductive genes in members of the virilis subgroup: D. americana, D. lummei, D. novamexicana, and D. virilis We find that the majority of male reproductive transcripts are testes-biased, accounting for ∼15% of all annotated genes. Ejaculatory bulb (EB)-biased transcripts largely code for lipid metabolic enzymes, and contain orthologs of the D. melanogaster EB protein, Peb-me, which is involved in mating-plug formation. In addition, we identify 71 candidate SFPs, and show that this gene set has the highest rate of nonsynonymous codon substitution relative to testes- and EB-biased genes. Furthermore, we identify orthologs of 35 D. melanogaster SFPs that have conserved accessory gland expression in the virilis group. Finally, we show that several of the SFPs that have the highest rate of nonsynonymous codon substitution reside on chromosomal regions, which contributes to paternal gametic incompatibility between species. Our results show that SFPs rapidly diversify in the virilis group, and suggest that they likely play a role in PCSS and/or gametic isolation.
