Biographical Memoir COPYRIGHT 1985 NATIONAL ACADEMY OF SCIENCES WASHINGTON D.C. THEODOSIUS DOBZHANSKY January 25, 1900-December 18, 1975 BY FRANCISCO J. AYALA HEODOSIUS DOBZHANSKY was born on January 25, 1900 Tin Nemirov, a small town 200 kilometers southeast of Kiev in the Ukraine. He was the only child of Sophia Voinarsky and Grigory Dobrzhansky (precise transliteration of the Russian family name includes the letter "r"), a teacher of high school mathematics. In 1910 the family moved to the outskirts of Kiev, where Dobzhansky lived through the tumultuous years of World War I and the Bolshevik revolu- tion. These were years when the family was at times beset by various privations, including hunger. In his unpublished autobiographical Reminiscences for the Oral History Project of Columbia University, Dobzhansky states that his decision to become a biologist was made around 1912. Through his early high school (Gymnasium) years, Dobzhansky became an avid butterfly collector. A schoolteacher gave him access to a microscope that Dob- zhansky used, particularly during the long winter months. In the winter of 1915—1916, he met Victor Luchnik, a twenty- five-year-old college dropout, who was a dedicated entomol- ogist specializing in Coccinellidae beetles.

  • Between Drosophila Species
    Copyright 0 1990 by the Genetics Society of America Evidence for Horizontal Transmission of theP Transposable Element Between Drosophila Species Stephen B. Daniels,* Kenneth R. Peterson: Linda D. Strausbaugh,* Margaret G. Kidwell+ and Arthur Chovnick*' *Department of Molecular and Cell Biology, University of Connecticut, Stows, Connecticut 06268, and ?Departmentof Ecology and Evolutionary Biology, University of Arizona, Tucson, Arizona 85721 Manuscript received September 2 1, 1989 Accepted for publication November 2, 1989 ABSTRACT Several studies have suggested that P elements have rapidly spread through natural populations of Drosophila melanogaster within the last four decades. This observation, together with the observation that P elements are absent in the otherspecies of the melanogaster subgroup, has lead to the suggestion that P elements may have entered the D. melanogaster genome by horizontal transmission from some more distantly related species. In an effort to identify the potential donor in the horizontal transfer event, we have undertaken an extensive survey of the genus Drosophila using Southern blot analysis. The results showed that P-homologous sequences are essentially confined to the subgenus Sophophora. The strongest P hybridization occurs in species from the closely related willistoni and saltans groups. The D. melanogaster P element is most similar to the elements from the willistoni group. A wild- derived strain of D. willistoni was subsequently selected for a more comprehensive molecular exami- nation. As part of the analysis, a complete P element was cloned and sequenced from this line. Its nucleotide sequence was found to be identical to the D. melanogaster canonical P, with the exception of a single base substitution at position 32.

  • Three Decades of Studies on Chromosomal Polymorphism of Drosophila Willistoni and Description of Fifty Different Rearrangements
    Genetics and Molecular Biology, 35, 4 (suppl), 966-979 (2012) Copyright © 2012, Sociedade Brasileira de Genética. Printed in Brazil www.sbg.org.br Research Article Three decades of studies on chromosomal polymorphism of Drosophila willistoni and description of fifty different rearrangements Claudia Rohde* and Vera Lúcia S. Valente Departamento de Genética, Instituto de Biociências, Universidade Federal do Rio Grande do Sul, Porto Alegre, RS, Brazil. Abstract Drosophila willistoni (Insecta, Diptera) is considered a paradigm for evolutionary studies. Their chromosomes are characterized by multiple paracentric inversions that make it hard to identify and describe chromosomal poly- morphisms. In the present report we attempted to systematize the description of all the 50 inversions found in the last three decades, since we have been studying the chromosomes of several individuals of 30 different populations, in- cluding the one used in the genome sequencing project (Gd-H4-1). We present the photographic register of 11 ar- rangements in the left arm of the X chromosome (XL), eight in the right arm (XR), 10 in the left arm of chromosome II (IIL), eight in its right arm (IIR) and 13 in chromosome III. This information also includes their breakpoints on the refer- ence photomap. A clear geographic difference was detected in XL and XR, with different fixed arrangements de- pending on the origin of the population studied. Through the comparison of all X arrangements it was possible to infer the putative ancestral arrangements, i.e., those related to all the remaining arrangements through the small number of inversions that occurred in the past, which we will call XL-A and XR-A.

Entomol. Soc. Am. 107(5): 975Ð982 (2014); DOI: http://dx.doi.org/10.1603/AN14052 ABSTRACT Cryptic species meet the biological deÞnition of species, but are morphologically identical or quite similar. Several ecological studies underestimate richness and neglect important information on cryptic species, as they are rather difÞcult to identify. Among insects, drosophilids of the willistoni subgroup, which includes Drosophila willistoni Sturtevant, Drosophila paulistorum Dobzhansky & Pavan, Drosophila equinoxialis Dobzhansky, Drosophila tropicalis Burla & da Cunha, Drosophila insularis Dobzhansky, and Drosophila pavlovskiana Kastritsis & Dobzhansky, are good examples of cryptic species. Although several studies have shown that this subgroup is one of the most abundant in the Neotropical region, no identiÞcation to species level has been reported for areas where these individuals live in sympatry. This study evaluates the seasonal oscillations in abundance of this subgroup in biomes with contrasting vegetation and rainfall regimes: the Caatinga and the Atlantic Forest, in northeastern Brazil. Approximately 39,000 drosophilids were captured in 24 collections, of which 18,000 belonged to the willistoni subgroup. The most abundant were D. willistoni, D. pauli- storum, and D. equinoxialis, in this order.

Ayala” Received by J.A. Engler: 21 December 1993: Revised/Accepted: 1 March/Z March 1994; Received at publishers: 13 June 1994 SUMMARY A Cu/Zn superoxide dismutase-encoding gene (Sod) from Drosophila willistoni was cloned and sequenced. The gene shows a typical structure for a fruit-fly Sod gene, with a coding region of 462 bp in two exons separated by a 417-bp intron. Comparison of the Sod sequences from D. willistoni and D. melanogaster suggests that these species are only remotely related. Downstream from the Sod gene, there is an ORF on the opposite strand that putatively encodes the last exon of an unidentified gene. The polyadenylation signals of the two genes are separated by only 61 bp in D. willistoni, conforming to the common picture of compact dipteran genomes.

  • Dissecting the Molecular Interplay Between Tomato Spotted Wilt Virus and the Insect Vector, Frankliniella Occidentalis
    DISSECTING THE MOLECULAR INTERPLAY BETWEEN TOMATO SPOTTED WILT VIRUS AND THE INSECT VECTOR, FRANKLINIELLA OCCIDENTALIS by ISMAEL E. BADILLO VARGAS B.S., University of Puerto Rico – Mayagüez, 2006 M.S., University of Wisconsin – Madison, 2008 AN ABSTRACT OF A DISSERTATION submitted in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Department of Plant Pathology College of Agriculture KANSAS STATE UNIVERSITY Manhattan, Kansas 2014 Abstract The Bunyaviridae is a family of animal and plant viruses that pose a threat to human, animal, and plant health worldwide. In nature, the dissemination of these viruses is dependent on arthropod vectors (genera Orthobunyavirus, Nairovirus, Phlebovirus, and Tospovirus) or rodent vectors (genus Hantavirus). The genus Tospovirus is the only one within this virus family that is composed of plant-infecting viruses transmitted by thrips. Tomato spotted wilt virus (TSWV), the type species of the Tospovirus genus, is one of the ten most devastating plant viruses known. It is most efficiently transmitted by the western flower thrips, Frankliniella occidentalis Pergande, in a persistant propagative manner. The insect molecules associated with virus infection and transmission by the thrips vector remain unidentified to date. The aim of this work was to identify F. occidentalis larval thrips proteins that are differentially expressed during TSWV infection of the insect vector and those that directly interact with TSWV. To achieve these goals, I used two-dimensional (2-D) gel electrophoresis and mass spectrometry coupled with Mascot searches. I identified 26 protein spots that displayed differential abundances in response to TSWV infection, which contained 37 proteins. Sixty two percent of these proteins were down-regulated by the viral infection demonstrating a complex response.

  • Drosophila Information Service
    Drosophila Information Service Number 103 December 2020 Prepared at the Department of Biology University of Oklahoma Norman, OK 73019 U.S.A. ii Dros. Inf. Serv. 103 (2020) Preface Drosophila Information Service (often called “DIS” by those in the field) was first printed in March, 1934. For those first issues, material contributed by Drosophila workers was arranged by C.B. Bridges and M. Demerec. As noted in its preface, which is reprinted in Dros. Inf. Serv. 75 (1994), Drosophila Information Service was undertaken because, “An appreciable share of credit for the fine accomplishments in Drosophila genetics is due to the broadmindedness of the original Drosophila workers who established the policy of a free exchange of material and information among all actively interested in Drosophila research. This policy has proved to be a great stimulus for the use of Drosophila material in genetic research and is directly responsible for many important contributions.” Since that first issue, DIS has continued to promote open communication. The production of this volume of DIS could not have been completed without the generous efforts of many people. Except for the special issues that contained mutant and stock information now provided in detail by FlyBase and similar material in the annual volumes, all issues are now freely-accessible from our web site: www.ou.edu/journals/dis. For early issues that only exist as aging typed or mimeographed copies, some notes and announcements have not yet been fully brought on line, but key information in those issues is available from FlyBase. We intend to fill in those gaps for historical purposes in the future.

Numerous studies have shown that genes with sex-biased expression are under- or over-represented on the X chromosomes of a wide variety of organisms. The patterns, however, vary between different animal species, and the causes of these differences are unresolved. Additionally, genes with sex-biased expres- sion tend to be narrowly expressed in a limited number of tissues, and narrowly expressed genes are also non-randomly X-linked in a taxon-specific manner.

Corresponding author: [email protected] Introduction Drosophila willistoni group (Diptera, Drosophilidae) is a Neotropical species group and is currently composed of 24 species distributed in three subgroups – alagitans, bocainensis, and willistoni (Bächli, 2015). The alagitans species group was established by Patterson and Mainland (1944), which reunited D. alagitans and D. capnoptera in a species group belonging to subgenus Drosophila (Wheeler and Magalhães, 1962). Later, Hsu (1949) observed that the male genitalia of these species resembled the willistoni species group and the alagitans group was later transferred to subgenus Sophophora (Wheeler, 1949). Wheeler and Magalhães (1962) described two new species for this subgroup – D. megalagitans and D. neoalagitans. Carson (1954) observed that three distinct specimens were designated as D. bocainensis; one of them was confirmed as D. bocainensis and the others redescribed as D. parabocainensis and D. bocainoides, establishing the bocainensis species complex (Carson, 1954). Salzano (1956) also reviewed the status of this species. Wheeler and Magalhães (1962) described some species belonging to this subgroup – D.

In the 17 years since the last familywide taxonomic analysis of the Drosophilidae, many stud- ies dealing with a limited number of species or groups have been published. Most of these studies were based on molecular data, but morphological and chromosomal data also contin- ue to be accumulated. Here, we review more than 120 recent studies and use many of those in a supertree analysis to construct a new phylogenetic hypothesis for the genus Drosophila and related genera. Our knowledge about the phylogeny of the genus Drosophila and related gen- era has greatly improved over the past two decades, and many clades are now firmly suppor- ted by many independent studies. The genus Drosophila is paraphyletic and comprises four major clades interspersed with at least five other genera, warranting a revision of the genus. Despite this progress, many relationships remain unresolved. Much phylogenetic work on this important family remains to be done. K. van der Linde & D.
