Analysis of olive fly invasion in California based on microsatellite markers
(2009)The olive fruit fly, Bactrocera oleae, is the main pest of the olive fruit and its expansion is exclusively restricted to the cultivation zone of the olive tree. Even though olive production has a century-old history in ... -
Ancestral populations perform better in a novel environment: domestication of Mediterranean fruit fly populations from five global regions
(2011)Geographically isolated populations of a species may differ in several aspects of life history, morphology, behaviour and genetic structure as a result of adaptation in ecologically diverse habitats. We used a global ... -
Comparison of essential oils and genetic relationship of Origanum x intercedens to its parental taxa in the island of Crete
(2002)Plants of the taxa Origanum onites and Origanum vulgare were allowed to cross-pollinate under natural open field conditions and to produce a mixed population of putative hybrid Origanum x intercedens and parent genotypes. ... -
A Comprehensive Phylogenetic Analysis of Deadenylases
(2013)Deadenylases catalyze the shortening of the poly(A) tail at the messenger ribonucleic acid (mRNA) 3'-end in eukaryotes. Therefore, these enzymes influence mRNA decay, and constitute a major emerging group of promising ... -
Diapause termination of Rhagoletis cerasi pupae is regulated by local adaptation and phenotypic plasticity: escape in time through bet-hedging strategies
(2014)Persistence and thriving of univoltine, herbivore insect species of the temperate zone rely on obligate diapause response that ensures winter survival and synchronization with host phenology. We used a stenophagous fruit ... -
From trickle to flood: the large-scale, cryptic invasion of California by tropical fruit flies
(2013)Since 1954, when the first tropical tephritid fruit fly was detected in California, a total of 17 species in four genera and 11 386 individuals (adults/larvae) have been detected in the state at more than 3348 locations ... -
Genetic evidence for introgression between domestic pigs and wild boars (Sus scrofa) in Belgium and Luxembourg: a comparative approach with multiple marker systems
(2013)Hybridization between wild species and their domestic relatives can be an important conservation and management problem. Genetic purity of the wild species is desirable per se and the phenomenon can have unpredictable ... -
Geographical variation in adult life-history traits of the European cherry fruit fly, Rhagoletis cerasi (Diptera: Tephritidae)
(2012)To understand the evolution of local adaptation, the interplay between natural selection and gene flow should be considered. Rhagoletis cerasi L. (Diptera: Tephritidae) is a patchily distributed, stenophagous species of ... -
Highly Dynamic Exon Shuffling in Candidate Pathogen Receptors ... What if Brown Algae Were Capable of Adaptive Immunity?
(2012)Pathogen recognition is the first step of immune reactions. In animals and plants, direct or indirect pathogen recognition is often mediated by a wealth of fast-evolving receptors, many of which contain ligand-binding and ... -
Intraspecific genetic variation of striped red mullet (Mullus surmuletus L.) in the Mediterranean Sea assessed by allozyme and random amplified polymorphic DNA (RAPD) analysis
(1999)Allozyme analysis on 20 putative enzyme-coding loci and RAPD analysis on 154 markers, amplified by eight decamer random primers, were used to assess the genetic variation of striped red mullet, Mullus surmuletus L., collected ... -
The invasion route for an insect pest species: the tobacco aphid in the New World
(2010)Biological invasions are rapid evolutionary events in which populations are usually subject to a founder event during introduction followed by rapid adaptation to the new environment. Molecular tools and Bayesian approaches ... -
Major histocompatibility complex variation at class II DQA locus in the brown hare (Lepus europaeus)
(2009)The major histocompatability complex (MHC) is a multigene family of receptors that bind and present antigenic peptides to T-cells. Genes of the MHC are characterized by an outstanding genetic polymorphism, which is considered ... -
Mitochondrial DNA variation in northeast atlantic and mediterranean populations of norway lobster, Nephrops norvegicus
(2004)Analysis of the genetic structure of the Norway lobster (Nephrops norvegicus), a marine crustacean with high commercial value, was undertaken to gain information regarding the differentiation of Atlantic from Mediterranean ... -
Molecular phylogenetic convergence within Elasmobranchii revealed by cytochrome oxidase subunits
(2015)The phylogenetic relationships within the subclass of Elasmobranchii are under question within the academic community and their systematic classification based on morphological, or physiological characteristics has not yet ... -
Phylogenetic relationships among four species of Mullidae (Perciformes) inferred from DNA sequences of mitochondrial cytochrome b and 16S rRNA genes
(2001)DNA sequence comparisons of two mitochondrial DNA genes were used to infer phylogenetic relationships among four species of mullids. Approximately 238 by of the mitochondrial 16S ribosomal RNA (rRNA) and 261 by of the ... -
Phylogeography of the rock partridge (Alectoris graeca)
(2003)We used mitochondrial DNA control-region and microsatellite data to infer the evolutionary history and past demographic changes in 332 rock partridges (Alectoris graeca ) sampled from throughout the species' distribution ... -
Polymorphic microsatellite markers in the olive fly, Bactrocera oleae
(2002)Bactrocera oleae is the single most important insect pest of the olive fruit, causing extensive of the losses in the olive production annually. Nonetheless, there has never been an analysis of the homogeneity of B. oleae ... -
Recent changes in the distribution of carboxylesterase genes and associated chromosomal rearrangements in Greek populations of the tobacco aphid Myzus persicae nicotianae
(2014)We present data on the frequency of amplified E4 and FE4 carboxylesterase genes in Myzus persicae s.l. clones collected during the years 2002-2007 and 2012 in Greece. Most clones were of the tobacco aphid, Myzus persicae ... -
Recombination in primeval genomes: A step forward but still a long leap from maintaining a sizable genome
(2004)A stubborn question in early molecular evolution is how to sustain the "minimum" informational length required for the basic features of life with a putative low-copying fidelity RNA polymerase ribozyme. Proposals to ...
