Here we report the molecular analysis of a computationally predicted Drosophila melanogaster microRNA gene, mir-282. We show that the mir-282 gene is the source of a 4.9 kb long primary transcript with a 5' cap and a 3' polyA sequence and a mature microRNA of about 25 bp. Our data strongly suggest the existence of an independent mir-282 gene conserved in holometabolic insects. We give evidence that the mir-282 locus encodes a functional transcript which influences viability, longevity, and egg production in Drosophila. We identify the nervous system-specific adenylate cyclase (rutabaga) as a target of miR-282 and assume that one of the main functions of mir-282 is the regulation of adenylate cyclase activity in the nervous system during metamorphosis.}, year = {2013}, eissn = {1943-2631}, pages = {469-480} } @article{MTMT:2046742, title = {CalpB modulates border cell migration in Drosophila egg chambers}, url = {https://m2.mtmt.hu/api/publication/2046742}, author = {Kókai, Endre and Páldy, FS and Somogyi, Kálmán and Chougule, Anil and Pál, Margit and Kerekes, Éva and Deák, Péter and Friedrich, P and Dombrádi, Viktor Béla and Ádám, Géza}, doi = {10.1186/1471-213X-12-20}, journal-iso = {BMC DEV BIOL}, journal = {BMC DEVELOPMENTAL BIOLOGY}, volume = {12}, unique-id = {2046742}, issn = {1471-213X}, year = {2012} } @article{MTMT:1921728, title = {Western Palaearctic phylogeography of an inquiline oak gall wasp, Synergus umbraculus}, url = {https://m2.mtmt.hu/api/publication/1921728}, author = {Bihari, Péter and Sipos, Botond and Melika, George and Feher, B and Somogyi, Kálmán and Stone, GN and Pénzes, Zsolt}, doi = {10.1111/j.1095-8312.2010.01609.x}, journal-iso = {BIOL J LINN SOC}, journal = {BIOLOGICAL JOURNAL OF THE LINNEAN SOCIETY}, volume = {102}, unique-id = {1921728}, issn = {0024-4066}, abstract = {Insect-induced galls on plants comprise species-rich but self-contained communities of herbivores and natural enemies. In the present study, we focus on galls induced by cynipid gall wasps on oaks, and on the least-known trophic level that these galls contain: inquilines. These insects, also cynipids, feed on gall tissue and are an abundant but taxonomically poorly understood part of an otherwise well-studied system. We used DNA sequence data to examine spatial patterns in the genetic diversity of Synergus umbraculus Olivier 1791 (Hymenoptera: Cynipidae: Synergini), a widespread species attacking many host galls across the Western Palaearctic. Analysis of 239 cytochrome b sequences revealed eight haplogroups showing significant phylogeographic pattern across the Western Palaearctic, corresponding to putative glacial refugia in Iberia, Central Europe, Turkey, and Iran. There were significant genetic discontinuities across the Pyrenees and the Anatolian diagonal but no impact of the Alps, suggesting that significant discontinuities have biotic rather than physical causes. Detailed analysis of sites in the Carpathian Basin reveal a high diversity and low spatial structure, and identify Central Europe as the source of colonists for Quaternary colonization of Germany, France, and Britain. We found no evidence for host-associated differentiation of S. umbraculus lineages associated with the most common cynipid host galls, suggesting frequent shifts within the host gall assemblage by inquiline lineages.

On the basis of structural features, nimrod genes can be divided into three types. The proteins encoded by Draper-type genes have an EMI domain at the N-terminal part and only one copy of the NIM motif, followed by a variable number of EGF-like repeats. The products of Nimrod B-type and Nimrod C-type genes (including the eater gene) have different kinds of N-terminal domains, and lack EGF-like repeats but contain a variable number of NIM repeats. Draper and Nimrod C-type (but not Nimrod B-type) proteins carry a transmembrane domain. Several members of the superfamily were claimed to function as receptors in phagocytosis and/or binding of bacteria, which indicates an important role in the cellular immunity and the elimination of apoptotic cells. In this paper, the evolution of the Nimrod superfamily is studied with various methods on the level of genes and repeats. A hypothesis is presented in which the NIM repeat, along with the EMI domain, emerged by structural reorganizations at the end of an EGF-like repeat chain, suggesting a mechanism for the formation of novel types of repeats. The analyses revealed diverse evolutionary patterns in the sequences containing multiple NIM repeats. Although in the Nimrod B and Nimrod C proteins show characteristics of independent evolution, many internal NIM repeats in Eater sequences seem to have undergone concerted evolution. An analysis of the nimrod genes has been performed using phylogenetic and other methods and an evolutionary scenario of the origin and diversification of the Nimrod superfamily is proposed. Our study presents an intriguing example how the evolution of multigene families may contribute to the complexity of the innate immune response.}, year = {2008}, eissn = {1537-1719}, pages = {2337-2347}, orcid-numbers = {Pénzes, Zsolt/0000-0003-0447-5997; Andó, István/0000-0002-4648-9396} } @article{MTMT:1916855, title = {T2prhd: a tool to study the patterns of repeat evolution}, url = {https://m2.mtmt.hu/api/publication/1916855}, author = {Sipos, Botond and Somogyi, Kálmán and Andó, István and Pénzes, Zsolt}, doi = {10.1186/1471-2105-9-27}, journal-iso = {BMC BIOINFORMATICS}, journal = {BMC BIOINFORMATICS}, volume = {9}, unique-id = {1916855}, issn = {1471-2105}, abstract = {Background: The models developed to characterize the evolution of multigene families (such as the birth-and-death and the concerted models) have also been applied on the level of sequence repeats inside a gene/protein. Phylogenetic reconstruction is the method of choice to study the evolution of gene families and also sequence repeats in the light of these models. The characterization of the gene family evolution in view of the evolutionary models is done by the evaluation of the clustering of the sequences with the originating loci in mind. As the locus represents positional information, it is straightforward that in the case of the repeats the exact position in the sequence should be used, as the simple numbering according to repeat order can be misleading. Results: We have developed a novel rapid visual approach to study repeat evolution, that takes into account the exact repeat position in a sequence. The "pairwise repeat homology diagram" visualizes sequence repeats detected by a profile HMM in a pair of sequences and highlights their homology relations inferred by a phylogenetic tree. The method is implemented in a Perl script (t2prhd) available for downloading at http://t2prhd.sourceforge.net and is also accessible as an online tool at http://t2prhd.brc.hu. The power of the method is demonstrated on the EGF-like and fibronectin-III-like (Fn-III) domain repeats of three selected mammalian Tenascin sequences. Conclusion: Although pairwise repeat homology diagrams do not carry all the information provided by the phylogenetic tree, they allow a rapid and intuitive assessment of repeat evolution. We believe, that t2prhd is a helpful tool with which to study the pattern of repeat evolution. This method can be particularly useful in cases of large datasets (such as large gene families), as the command line interface makes it possible to automate the generation of pairwise repeat homology diagrams with the aid of scripts.}, year = {2008}, eissn = {1471-2105}, pages = {AR27}, orcid-numbers = {Andó, István/0000-0002-4648-9396; Pénzes, Zsolt/0000-0003-0447-5997} } @article{MTMT:1657711, title = {New species of oak gallwaps from Iran (Hymenoptera: Cynipidae: Cynipini)}, url = {https://m2.mtmt.hu/api/publication/1657711}, author = {Tavakoli, M and Melika, G and Sadeghi, SE and Pénzes, Zsolt and Assareh, MA and Atkinson, R and Bechtold, M and Miko, I and Zargaran, MR and Aligolizade, D and Barimani, H and Bihari, Péter and Pirozi, F and Fülöp, Dávid Krisztián and Somogyi, Kálmán and Challis, R and Preuss, S and Nicholls, J and Stone, GN}, doi = {10.11646/zootaxa.1699.1.1}, journal-iso = {ZOOTAXA}, journal = {ZOOTAXA}, volume = {2008}, unique-id = {1657711}, issn = {1175-5326}, abstract = {Fourteen new species of oak gallwasps, Andricus istvani, Andricus assarehi, Andricus schoenroggei, Andricus csokai, Andricus chodjaii, Andricus megatruncicolus, Andricus coriariformis, Andricus libani, Andricus stellatus, Andricus pseudoaries, Andricus sadeghii, Andricus atkinsonae, Andricus pujadevillari and Dryocosmus caspiensis ( Hymenoptera: Cynipidae: Cynipini) are described from Iran.
