Translational control of gurken mRNA in Drosophila development

Localized mRNA translation is a widespread mechanism for targeting protein synthesis, important for cell fate, motility and pathogenesis. In Drosophila, the spatiotemporal control of gurken/TGF-α mRNA translation is required for establishing the embryonic body axes. A number of recent studies have highlighted key aspects of the mechanism of gurken mRNA translational control at the dorsoanterior corner of the mid-stage oocyte. Orb/CPEB and Wispy/GLD-2 are required for polyadenylation of gurken mRNA, but unlocalized gurken mRNA in the oocyte is not fully polyadenylated.¹ Norvell A, Wong J, Randolph K, Thompson L. Wispy and Orb cooperate in the cytoplasmic polyadenylation of localized gurken mRNA. Dev Dyn Off Publ Am Assoc Anat 2015; 244:1276-1285. [Google Scholar] At the dorsoanterior corner, Orb and gurken mRNA have been shown to be enriched at the edge of Processing bodies, where translation occurs.² Weil TT, Parton RM, Herpers B, Soetaert J, Veenendaal T, Xanthakis D, Dobbie IM, Halstead JM, Hayashi R, Rabouille C, et al. Drosophila patterning is established by differential association of mRNAs with P bodies.

Together with our new findings we consolidate the literature into a working model for gurken mRNA translational control and review the role of kinases, cell cycle factors and polyadenylation machinery highlighting a multitude of conserved factors and mechanisms in the Drosophila egg chamber.

Cryptic diversity among the achaetous Marionina (Annelida,Clitellata, Enchytraeidae)

This study investigates the diversity and taxonomy of a mainly marine group of species lacking chaetae currently assigned to the genus Marionina. This achaetous group includes four nominal species: M. achaeta (Hagen, 1954 Hagen, G. 1954. Michaelsena achaeta nov. sp., ein neuer mariner Oligochaet aus der Kieler Bucht. Faunistische Mitteilungen aus Norddeutschland, 1: 12–13.  [Google Scholar]), M. achaeta sensu Lasserre, 1964 Lasserre, P. 1964.

Procés-Verbaux des Séances de la Société Linnéenne de Bordeaux, 101: 87–91.  [Google Scholar], M. nevisensis Righi & Kanner, 1979 Righi, G. and Kanner, E. 1979. Marine Oligochaeta (Tubificidae and Enchytraeidae) from the Caribbean Sea.

Marine fauna of County Wexford. 1 – Littoral and brackishwater Oligochaeta. The Irish Naturalists' Journal, 19: 418–422.  [Google Scholar]. As Lasserre's (1964 Lasserre, P. 1964. Notes sur quelques oligochètes Enchytraeidae présents dans les plages du Bassin d’Arcachon. Procés-Verbaux des Séances de la Société Linnéenne de Bordeaux, 101: 87–91.  [Google Scholar]) M. achaeta appears to be morphologically different from its (then) senior homonym M. achaeta (Hagen, 1954 Hagen, G. 1954. Michaelsena achaeta nov. sp., ein neuer mariner Oligochaet aus der Kieler Bucht. Faunistische Mitteilungen aus Norddeutschland, 1: 12–13.  [Google Scholar]), the replacement name M. nothachaeta nom. nov. is proposed for it. We studied the genetic and morphological diversity of achaetous specimens of Marionina collected in Florida, the Great Barrier Reef, New Caledonia, Sweden, England and the Bahamas. The collection localities are almost all supralittoral and often brackish-water habitats. Parts of the mitochondrial genes 12S, 16S, COI and the nuclear genes 18S, 28S and ITS were analysed to assess the genetic variation and phylogeny of the achaetous Marionina species. The molecular data reveal one monophyletic group of 11 separately evolving lineages, and between these lineages, K2P distances in the barcoding gene COI vary between 5.4 and 25.0%. On a morphological basis, the lineages could be assigned to seven different groups (morphotypes), of which only two could be identified as described nominal taxa: M. nevisensis s. lat. (several lineages) and M. nothachaeta. Since the former taxon appears to be a complex of cryptic species around the world and the original type material no longer exists, a neotype from the Caribbean was designated for M. nevisensis s. str. The remaining achaetous lineages represent five morphologically distinct species that are left unnamed, awaiting finer morphological scrutiny and detailed comparisons with new collections of M. achaeta and M. arenaria. Summing up, the group of achaetous Marionina now seems to contain up to 13 different species, seven of which are yet to be formally described and named.     

Catoptinae subfam. n., a new subfamily of carpenter-moths (Lepidoptera,Cossidae)

The new subfamily of Cossidae; Catoptinae Yakovlev, subfam. n., well distinguished from other representatives of the family, is described. The new subfamily includes two genera: Catopta Staudinger, 1899 (type genus) and Chiangmaiana Kemal et Koçak, 2006. A catalogue of the subfamily is presented. One new synonym Catopta hyrcanus (Christoph, 1888) = Catopta brandti Bryk, 1947, syn. n., is established. The new subfamily has the following distinguishing features: short valvae; reduced processes of transtilla; vesica with numerous cornuti; pearshaped bursa copulatrix; and very short ductus bursae.     

Redefinition of the hypotrichous ciliate Uncinata,with descriptions of the morphology and phylogeny of three urostylids (Protista,Ciliophora)

We investigated the morphology, morphogenesis and small subunit rRNA gene-based phylogeny of three marine urostylids, Uncinata gigantea Bullington, 1940 Bullington, W. E. (1940). Some ciliates from Tortugas. Papers from the Tortugas Laboratory, 32, 179–221. [Google Scholar], Holosticha heterofoissneri Hu & Song, 2001 Hu, X., & Song, W. (2001). Morphology and morphogenesis of Holosticha heterofoissneri n. sp. from the Yellow Sea, China (Ciliophora, Hypotrichida). Hydrobiologia, 448, 171–179. doi:10.1023/A:1017553406031.[Crossref], [Web of Science ®] , [Google Scholar], and Holosticha cf. heterofoissneri. The dorsal morphogenesis of Uncinata gigantea shows de novo formation of two groups of anlagen near the marginal rows. Holosticha cf. heterofoissneri demonstrates fragmentation of the first dorsal kinety anlage as in Holosticha heterofoissneri. Our population of H. heterofoissneri corresponds well with previously described populations in terms of its general morphology and ciliary pattern. Uncinata gigantea can be recognized by its large and highly contractile body, yellowish to brownish cell colour, two types of cortical granules, and 20–30 transversely oriented and densely arranged cirri in the left marginal row, which often overlie the buccal vertex. Based on the new data, especially infraciliature, the genus Uncinata is here redefined. Both the morphology and phylogenetic analyses suggest that the genus Uncinata should be classified within the family Urostylidae. In addition, both morphological and morphogenetic data suggest that Holosticha bradburyae Gong et al., 2001 Gong, J., Song, W., Hu, X., Ma, H., & Zhu, M. (2001). Morphology and infraciliature of Holosticha bradburyae n. sp. (Ciliophora, Hypotrichida) from the Yellow Sea, China.

(2001). Morphology and infraciliature of Holosticha bradburyae n. sp. (Ciliophora, Hypotrichida) from the Yellow Sea, China. Hydrobiologia, 464, 63–69. doi:10.1023/A:1013901621439.[Crossref], [Web of Science ®] , [Google Scholar]) comb. nov., due to its possession of a characteristically prominent beak-like, leftwards curved projection and the developmental mode of the dorsal kineties. This assignment is supported by the phylogenetic analyses, which placed Uncinata gigantea in a clade with U. bradburyae (Gong et al., 2001 Gong, J., Song, W., Hu, X., Ma, H., & Zhu, M. (2001). Morphology and infraciliature of Holosticha bradburyae n. sp. (Ciliophora, Hypotrichida) from the Yellow Sea, China. Hydrobiologia, 464, 63–69. doi:10.1023/A:1013901621439.[Crossref], [Web of Science ®] , [Google Scholar]) comb. nov., and revealed only 1.13% (19 bp) difference in their SSU-rDNA gene sequence.     

Neotropical Osmylidae larvae (Insecta,Neuroptera): description of habitats and morphology

ABSTRACT

The larval stages of the genus Kempynus Navás, 1912 Navás, L. (1912), ‘Insectos neurópteros nuevos o poco conocidos’, Memorias de la Real Academia de Ciencias y Artes de Barcelona, 10, 135–202. [Google Scholar] (probably K. falcatus Navás, 1912 Navás, L. (1912), ‘Insectos neurópteros nuevos o poco conocidos’, Memorias de la Real Academia de Ciencias y Artes de Barcelona, 10, 135–202. [Google Scholar] based on the presence of synchronic and sympatric adults) are described for the Neotropical Region for the first time, and the larval stages of Isostenosmylus pulverulentus (Gerstaecker, 1893 Gerstaecker, C.E.A. (1893), ‘Ueber neue und weniger gekannte Neuropteren aus der familie Megaloptera Burm’, Mitt[h]eilungen aus dem Naturwissenschaftlichen Verein für Neu-Vorpommern und Rugen, 25, 93–173. [Google Scholar]) are redescribed. The external morphology of third-instar larvae of both species and their habitats are described and compared. Kempynus sp. is a water-dependent species and can be considered semi-aquatic, whereas I. pulverulentus larvae are terrestrial and live in undergrowth vegetation. The first key to identification of Neotropical Osmylidae larvae is provided, based on third-instar larvae of both species.
