Moreover, the complex asymmetric virion, lacking elements with icosahedral or regular helical symmetry, with two completely different structures at each end and an envelope encasing a funnel-shaped core represents, as far as we can judge, represents a principally novel type of virus particle. The funnel-shaped core of the enveloped virion consists of three distinct structural units: the “stopper”, the nucleoprotein cone, consisting of double-stranded DNA and DNA-binding proteins, and the inner core. -
Genetic Disequilibria and the Interpretation of Population Genetic Structure in Daphnia
Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 668 _____________________________ _____________________________ Genetic Disequilibria and the Interpretation of Population Genetic Structure in Daphnia BY LARS M. BERG ACTA UNIVERSITATIS UPSALIENSIS UPPSALA 2001 Dissertation for the Degree of Doctor of Philosophy in Conservation Biology presented at Uppsala University in 2001. ABSTRACT Berg, L. M. 2001. Genetic disequilibria and the interpretation of population genetic structure in Daphnia. Acta Universitatis Upsaliensis. Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 668. 36 pp. Uppsala. ISBN 91-554-5152-7. Understanding the processes that shape the spatial distribution of genetic variation within species is cent- ral to the evolutionary study of diversification and demography. Neutral genetic variation reflects past demographic events as well as current demographic characteristics of populations, and the correct inter- pretation of genetic data requires that the relative impact of these forces can be identified. Details of breeding systems can affect the genetic structure through effects on effective migration rate or on effect- ive population size. Restrictions in recombination rate lead to associations between neutral marker genes and genes under natural selection. Although the effects on genetic structure can be substantial, the pro- cess will often be difficult to tell apart from stochastic effects of history or genetic drift, which may sug- gest -

Ultrastructure and Development of Pasteuria Sp. (S-1 Strain), an Obligate Endoparasite of Belonolaimus Longicaudatus (Nemata: Tylenchida) R
Journal of Nematology 33(4):227–238. 2001. © The Society of Nematologists 2001. Ultrastructure and Development of Pasteuria sp. (S-1 strain), an Obligate Endoparasite of Belonolaimus longicaudatus (Nemata: Tylenchida) R. M. Giblin-Davis,1 D. S. Williams,2 W. P. Wergin,3 D. W. Dickson,4 T. E. Hewlett,4 S. Bekal,5 and J. O. Becker5 Abstract: Pasteuria sp., strain S-1, is a gram-positive, obligate endoparasitic bacterium that uses the phytoparasitic sting nematode, Belonolaimus longicaudatus, as its host in Florida. The host attachment of S-1 appears to be specific to the genus Belonolaimus with development occurring only in juveniles and adults of B. longicaudatus. This bacterium is characterized from other described species of Pasteuria using ultrastructure of the mature endospore. Penetration, development, and sporogenesis were elucidated with TEM, LTSEM, and SEM and are similar to other nematode-specific Pasteuria. Recent analysis of 16S rDNA sequence homology confirms its congeneric ranking with other Pasteuria species and strains from nematodes and cladocerans, and corroborates ultrastructural, morphological, morphometric, and host-range evidence suggesting separate species status. Key words: Belonolaimus longicaudatus, development, obligate nematode endoparasitic bacterium, Pasteuria sp. (S-1 strain), sporo- genesis, sting nematode, ultrastructure. Investigators have identified four nominal species of al., 1989). Thus, traditional procedures for biochemical Pasteuria that are gram-positive, mycelial, endospore- characterization have not -
