  • The Evolutionary Life History of P Transposons: from Horizontal Invaders to Domesticated Neogenes

  • Diptera: Drosophilidae) from China
    Zoological Systematics, 40(1): 70–78 (January 2015), DOI: 10.11865/zs.20150107 ORIGINAL ARTICLE A new species of Drosophila obscura species group (Diptera: Drosophilidae) from China Ji-Min Chen, Jian-Jun Gao* Laboratory for Conservation and Utilization of Bioresources, Yunnan University, Kunming 650091, China *Corresponding author, E-mail: [email protected] Abstract A new species of the Drosophila obscura species group is described here, namely Drosophila glabra sp. nov. It was recently found from the Maoershan National Nature Reserve, Guangxi, China. The characteristics of the new species are based not only on morphological characters but also on DNA sequences of the mitochondrial COII (cytochrome c oxidase subunit II) gene. Key words Genetic distance, morphology, Old World, Oriental Region, Sophophora. 1 Introduction The Drosophila obscura species group is one of the major lineages within the well-known sophophoran radiation recognized by Throckmorton (1975). Studies on the taxonomy, geography, chromosomal evolution, reproductive-isolation, protein polymorphism and phylogeny of this group have greatly promoted the early development of evolutionary genetics (Lakovaara & Saura, 1982). A majority of the currently known species of this group (44 in total) was recorded from the Holarctic temperate zone, with the remainder recorded from varied sites in South America (Lakovaara & Saura, 1982; Head & O’Grady, 2000), as well the Afrotropical (Séguy, 1938; Tsacas et al., 1985) and Oriental Regions (Watabe et al., 1996; Watabe & Sperlich, 1997; Gao et al., 2003, 2009; Table 1). In this paper, we describe a new species of the obscura group found from our recent field survey in Guangxi, China. The definition of the new species is based on morphological characters and DNA sequences of the mitochondrial COII (cytochrome c oxidase subunit II) gene.

  • View of the Invasion of Drosophila Suzukii in Gether with the 5′ UTR (Annotated in Green) Are Compared
    Yan et al. BMC Genetics 2020, 21(Suppl 2):146 https://doi.org/10.1186/s12863-020-00939-y RESEARCH Open Access Identification and characterization of four Drosophila suzukii cellularization genes and their promoters Ying Yan1,2*, Syeda A. Jaffri1, Jonas Schwirz2, Carl Stein1 and Marc F. Schetelig1,2* Abstract Background: The spotted-wing Drosophila (Drosophila suzukii) is a widespread invasive pest that causes severe economic damage to fruit crops. The early development of D. suzukii is similar to that of other Drosophilids, but the roles of individual genes must be confirmed experimentally. Cellularization genes coordinate the onset of cell division as soon as the invagination of membranes starts around the nuclei in the syncytial blastoderm. The promoters of these genes have been used in genetic pest-control systems to express transgenes that confer embryonic lethality. Such systems could be helpful in sterile insect technique applications to ensure that sterility (bi-sex embryonic lethality) or sexing (female-specific embryonic lethality) can be achieved during mass rearing. The activity of cellularization gene promoters during embryogenesis controls the timing and dose of the lethal gene product. Results: Here, we report the isolation of the D. suzukii cellularization genes nullo, serendipity-α, bottleneck and slow-as- molasses from a laboratory strain. Conserved motifs were identified by comparing the encoded proteins with orthologs from other Drosophilids. Expression profiling confirmed that all four are zygotic genes that are strongly expressed at the early blastoderm stage. The 5′ flanking regions from these cellularization genes were isolated, incorporated into piggyBac vectors and compared in vitro for the promoter activities.

  • FRANCIS M. CARNEY July 20, 1998
    Transcription of Video Interview with FRANCIS M. CARNEY July 20, 1998 Erickson: Professor Carney, would you tell us where you were born and a little about your family, please? Carney: Yes. I was born in New York City in 1921. That makes me now 76, and I was born in the Bronx. My mother and father and my younger brother and I, (younger brother Matt, younger than I by a little over a year) came out to Los Angeles in 1924. I was not quite three years old. We settled in LA, in Hollywood actually. My mother was working in pictures and my father was a postal worker. They got a divorce about 1927, I think. I lived in North Hollywood and went to public schools in Southern California and then to St. Catherine’s Military Academy in Anaheim for five years and then to Villanova Preparatory Academy in Ojai for a year and a half and then to North Hollywood High. I graduated from North Hollywood High School in North Hollywood in 1939. I went to Stanford and into the Army, into the Air Force. It was then the Army Air Force in World War II, and I flew in Europe on a troop carrier command in 1944 as an aircraft radio operator. Came home in 1945 and married a young lady I had met in Vermont during the summertime. My family had a place on a lake there. I met her back before 1939 or ’40. We got married and had three children, three girls: Susan, the oldest; and Diane, the middle one; and Robin, the youngest.

Relative rate tests suggest that evolution of permit the use of LHP as a tool for estimating times of hemolymph proteins has been about as fast in Hawaii as on divergence (11). continents.

According Our analysis suggests that rates of LHP evolution are not to this scale, the Hawaiian fly fauna stems from a colonist that accelerated within the Hawaiian drosophilines, supporting landed on the archipelago about 42 million years ago-i.e., the use of LHP as an estimator of divergence times.

We have found that two sigma viruses (Rhabdoviridae) recently 40 discovered in Drosophila affinis and Drosophila obscura are both vertically 41 transmitted. As is the case for the sigma virus of Drosophila melanogaster, we find 42 that both males and females can transmit these viruses to their offspring. Males 43 transmit lower viral titres through sperm than females transmit through eggs, and a 44 lower proportion of their offspring become infected.
