The eukaryotic phylum Apicomplexa encompasses thousands of obligate intracellular parasites humans and animals with immense socio-economic health impacts. We sequenced nuclear genomes Chromera velia Vitrella brassicaformis, free-living non-parasitic photosynthetic algae closely related to apicomplexans. Proteins from key metabolic pathways the endomembrane trafficking systems associated a lifestyle have been progressively non-randomly lost during adaptation parasitism. ancestor contained...
Four respiratory complexes and ATP-synthase represent central functional units in mitochondria. In some mitochondria derived anaerobic organelles, a few or all of these have been lost during evolution. We show that the chain Chromera velia, phototrophic relative parasitic apicomplexans, lacks I III, making it uniquely reduced aerobic mitochondrion. Chromera, putative lactate:cytochrome c oxidoreductases are predicted to transfer electrons from lactate cytochrome c, rendering complex III...
Abstract In the fig (Moraceae) and fig‐wasp (Agaonidae) mutualism, scent is believed to be of primary importance in pollinator attraction maintenance species specificity. Scent divergence between closely related Ficus seems sufficient promoting reproductive isolation through behaviour, starting process speciation. We investigated volatile organic compound ( VOC ) variation from figs several endemic Papua New Guinea. Sister section Papuacyse subspecies trichocerasa substitute each other along...
The Salicaceae includes approximately 54 genera and over 1,400 species with a cosmopolitan distribution. Members of the family are well-known for their diverse secondary plant metabolites, they play crucial roles in tropical temperate forest ecosystems. Phylogenetic reconstruction has been historically challenging due to limitations molecular markers extensive history hybridization polyploidy within family. Our study employs whole-genome sequencing 74 generate an phylogeny Salicaceae. We...
Even though speciation involving multiple interacting partners, such as plants and their pollinators, has attracted much research, most studies focus on isolated phases of the process. This currently precludes an integrated understanding mechanisms leading to cospeciation. Here, we examine population genetic structure across six species-pairs figs pollinating wasps along elevational gradient in New Guinea. Specifically, test three hypotheses within examined find that hypothesized structures...
Plants produce diverse chemical defenses with contrasting effects on different insect herbivores. Deploying herbivore-specific responses can help plants increase their defensive efficiency. Here, we explore how variation in induced plant correlates herbivore species, order, feeding guild, and level of specialization. In a greenhouse experiment, exposed 149
Abstract Environmental requirements to reduce CO 2 emissions and the drive towards higher efficiencies have resulted in increased operating temperatures gas turbines. Subsequently, Original Equipment Manufacturer (OEMs) require improved component design material selection withstand harsher conditions. This demands rapid evaluation of new components their surface temperature accelerate market entry. Accurate information proves key more efficient, longer-lasting machinery monitoring thermal...
Abstract The aim of this paper is to explore and define the boundary zone inland, mainly agricultural settlement in southern western Bohemia, Czech Republic later prehistory, try determine why such appears not have spread further into Šumava foothills mountains. With help predictive MaxEnt modelling – used ecology degree uncertainty geographic distribution species using a comparison with data on soil productivity, we whether prehistory was limited by unsuitable natural conditions or other...
Abstract The fig (Moraceae) and pollinating wasp (Agaonidae) mutualism is best known as a model system for the study of coevolution in plant–pollinator interactions its central role shaping vertebrate communities tropical forests. Figs also host myriad antagonistic parasitic wasps which impose costs on both partners threatening stability. Spatiotemporal variation abundance key factor mitigating these effects. Because are temperature sensitive likely vary their ability to traverse...
Two dominant central European tree species (Fagus sylvatica L. and Picea abies (L.) Karst.), in a mixed culture semi-open glass domes, were used to simulate the reaction of forests long-term elevated CO 2 (EC) mountainous area (Beskydy Mountains, Czech Republic). We investigated effects EC on soluble carbohydrate levels composition. Starch content was evaluated using two methods: biochemical (glucose after enzymatic hydrolysis) stereological (starch grain proportion, size, number...

Fatty acids are essential components of biological membranes, important for the maintenance cellular structures, especially in organisms with complex life cycles like protozoan parasites. Apicomplexans obligate parasites responsible various deadly diseases humans and livestock. We analyzed fatty produced by closest phototrophic relatives parasitic apicomplexans, chromerids

Příspěvek se věnuje nálezům odkrytým na Vraném vrchu u Spolí, okr. Český Krumlov. V nadmořské výšce 635 m paty skalního výběžku svahu spadajícím příkře k Vltavě byla v hl. 20 cm nalezena skupina šesti bronzových náramků z pozdní doby halštatské. Při následném sondážním výzkumu ověřujícím místo nálezu ve stejné hloubce našlo deset zlomků dislokovaných lidských kostí dospělého jedince, těsné blízkosti ležel skleněný kroužek hnědožluté barvy o průměru 34 mm. Celková situace svědčí pravděpodobně...
Reproductive isolation in response to divergent selection is often mediated via third-party interactions. Under these conditions, speciation inextricably linked ecological context. We present a novel framework for understanding arthropod as by Wolbachia, microbial endosymbiont capable of causing host cytoplasmic incompatibility (CI). predict that sympatric sister-species harbor paraphyletic Wolbachia strains provide CI, while well-defined congeners contact and recently diverged...
