Summary Rapid climate change both imposes strong selective pressures on natural populations – potentially reducing their growth rate and causing genetic evolution affects the physiology development of individual organisms. Understanding predicting fates under global change, including extinctions geographical range shifts, requires analysing interplay these processes, which has long been a grey area in evolutionary biology. We review recent theory interaction phenotypic plasticity, demography...
Current strategies to prevent or treat human papillomavirus type 16 (HPV-16) infection are promising, but remain costly. More economical efficient vaccines thus needed. In this study, we evaluated the protective effects of mucosally coadministered live Lactococcus lactis strains expressing cell wall-anchored E7 Ag and a secreted form IL-12 HPV-16-induced tumors in murine model. When challenged with lethal levels tumor line TC-1 E7, immunized mice showed full prevention TC-1-induced tumors,...
The sustainability of agro-ecosystems depends on their ability to deliver an entire package multiple ecosystem services, rather than provisioning services alone. New social and ecological dimensions agricultural management must be explored in landscapes, foster this ability. We propose a social–ecological framework for the service-based agro-ecosystems, specified through explicit symmetric representation system, dynamic links between them. It highlights how practices, with effects, could...
Abstract The relationships that control seed production in trees are fundamental to understanding the evolution of forest species and their capacity recover from increasing losses drought, fire, harvest. A synthesis fecundity data 714 worldwide allowed us examine hypotheses central quantifying reproduction, a foundation for assessing fitness trees. Four major findings emerged. First, is not constrained by strict trade-off between size numbers. Instead, numbers vary over ten orders magnitude,...
We have characterized a new gene, SWI1, involved in sister chromatid cohesion during both male and female meiosis Arabidopsis thaliana. A first allele, swi1.1, was obtained as T-DNA tagged mutant described previously abnormal exclusively meiosis. isolated swi1.2, which is defective for In swi1.2 meiosis, the classical steps of prophase were not observed, especially because homologs do synapse. Chromatid arms centromeres lost their stepwise manner before metaphase I, 20 chromatids instead...
Summary 1 We used genetic markers to study gene flow of the riparian pioneer tree species Populus nigra along Drôme river (France). This dioecious is supposed have more efficient dispersal mechanisms for pollen (wind) and seeds (wind water) than other trees. 2 Seedlings belonging same reproduction/migration event were sampled in 22 forest fragments their diversity assessed through six nuclear microsatellites. 3 found a high level significant differentiation among populations. The isolation...
Managing forests under climate change requires adaptation. The adaptive capacity of forest tree populations is huge but not limitless. Integrating evolutionary considerations into forestry practice will enhance the managed to respond climate-driven changes. Focusing on natural regeneration systems, we propose a general framework that can be used in various and complex local situations by managers, combination with their own expertise, integrate decision making for emergence an...
Abstract Dynamic conservation of forest genetic resources (FGR) means maintaining the diversity trees within an evolutionary process and allowing generation turnover in forest. We assessed network forests areas managed for dynamic FGR (conservation units) across Europe (33 countries). On basis information available European Information System on (EUFGIS Portal), species distribution maps, environmental stratification continent, we developed ecogeographic indicators, a marginality index,...
Summary. Antiviral activities present in uterine flushings from pregnant Large White, White 'hyperprolific', and prolific Meishan gilts, between Days 8 20 of gestation were compared. Flushings (20 ml) all gilts 14 positive an in-vitro interferon (IFN) assay using vesicular stomatitis virus as a challenge infection. Highest antiviral (of up to 400 000–1 200 000 total Units/flushing) obtained at Day 16 gestation, i.e. clearly after the beginning attachment. There was no major difference breeds...
Low stringency screening of day 14-15 pig conceptus cDNA library using an interferon (IFN)-omega probe has led to the isolation a novel type one (type I) IFN gene physiologically expressed by trophoblast during period implantation in uterus. It encodes 170-amino acid preprotein with two potential N-glycosylation sites and predicted N-terminal signal peptide 21 residues. This protein was shorter richer Cys residues than other I IFNs distantly related all them including IFN-tau, ruminants,...
Abstract There is an increasing recognition that long distance dispersal (LDD) plays a key role in establishing spatial genetic structure during colonization. Recent works, focused on short dispersal, demonstrated neutral mutation arising at the colonization front can either ‘surf’ with wave and reach high frequencies or stay near its place of origin low frequencies. Here, we examine how LDD, more generally shape kernel, modifies this phenomenon width corridor affects fate mutation. We...
A transnational network of genetic conservation units for forest trees was recently documented in Europe aiming at the evolutionary processes and adaptive potential natural or man-made tree populations. In this study, we quantified vulnerability individual whole to climate change using favourability models estimated velocity change. Compared overall niche analysed target species populations warm dry end are underrepresented network. However, by 2100, 33-65 % units, mostly located southern...
Abstract Purpose of Review Recognizing that in the context global change, tree genetic diversity represents a crucial resource for future forest adaptation, we review and highlight major genetics research achievements past decades biodiversity-rich countries Mediterranean region. For this, conducted bibliometric analysis scientific literature spanning thirty years (1991–2020). Putting together representative regionwide expertise our co-authorship, propose perspectives next decade. Recent...
As drought-induced mortality increases globally in forest biomes, it becomes necessary for foresters to have access reliable predictors of species vulnerability drought and risk under different climatic scenarios. On the one hand, there exist several "operational" indicators resistance, which are based on observations, expert knowledge bioclimate (e.g. Ellenberg, Rameau, ClimEssences). other as traits can now be measured at high throughput, functional (such plant hydraulic traits) been...
