Summary: In this study, 67 GST genes were identified in the sweet cherry genome, classified into seven chief subfamilies according to phylogenetic tree analysis. Most PavGST genes showed relatively well-maintained exon-intron and motif arrangement within the same group, as revealed by gene structure and motif analyses. The findings provide a foundation for future research on LED-induced anthocyanin and antioxidants accumulation in sweet cherries.

Summary: This study investigates how costly female preference for exaggerated male display traits can be facilitated by genetic drift and spatially variable sexual selection in structured populations. The results show that genetic drift initially creates spatial variation in female preference, fueling the coevolution of costly preference and display traits, but costs of sexual selection increase the probability of subpopulation extinction.

Summary: This study investigated the self-(in)compatibility of the sweet cherry cultivar 'Karina' and found that 'Karina' exhibited self-compatibility after selfing, but did not set fruit when pollinated with cultivars of the same S-allele constitution. Further molecular and genetic analysis is needed to understand the behavior of 'Karina' in selfing, as well as its behavior as the pollen donor/recipient in pollination with cultivars of the same S-allele constitution.

Summary: In this study, a Markov birth-and-death process on a space of locally finite configurations was analyzed to describe an ecological model with a density-dependent fecundity regulation mechanism. The existence and uniqueness of this process were established and properties such as global time-space boundedness of population density were examined. Furthermore, conditions for the unique degenerate invariant distribution for the process were identified.

Summary: This study examines the genetic and gene flow patterns of European beech populations during range expansion in Mont Ventoux, Southeastern France. Despite colonization signs, genetic diversity and structure of beech populations were not influenced by founder effects. Genetic diversity increased along the expansion front, while genetic differentiation from the entire pool decreased, indicating beech's ability to maintain high genetic diversity and adaptive potential under climate change.

Summary: The study demonstrates two complementary behaviors in the probability distributions of genotypic and genetic indices with increasing rates of clonality. Genotypic indices provide reliable estimates of clonality, while genetic descriptors perform poorly for clonality levels below 0.95.

Summary: The study investigates sexual dimorphism in plants, specifically in the dioecious wind-pollinated shrub Leucadendron rubrum, and suggests that sexual differences exist in selection of traits and effective fecundity. While males exhibit stronger spatial autocorrelation in effective fecundity at a smaller scale, higher plant density is associated with lower effective fecundity in males but not in females. Despite these sex-specific sensitivities to environmental heterogeneity, directional selection for certain traits is observed in both sexes without sexually antagonistic selection on strongly dimorphic traits.

Summary: Recurrent selection of euploid plants for eight generations significantly reduced the percentage of aneuploid progenies and the number of newly fixed homoeologous rearrangements, promoting genome stability. The effects of homoeologous rearrangements on meiotic behavior and seed number depended strongly on the genetic background and cytoplasm donor.

Summary: This study investigates the effects of environmental heterogeneity, selection intensity, and QTL on local adaptation. The results demonstrate that within-population environmental heterogeneity plays a significant role in migration success, adaptive differentiation, occupancy rate, and genetic variance.

Summary: This study used bibliographic analysis to explore the field of resistance durability in plant protection. It identified three subfields and argues that the split impedes integrated research progress. The study suggests that population genetics can bridge the gap and provide a comprehensive view of pathogen adaptation, particularly through evolutionary-epidemiological feedbacks. Examples are provided to illustrate how this framework can inform best practices for developing and managing genetically resistant cultivars.

Summary: The advantage and fixation of sex in many eukaryote species is considered a evolutionary puzzle. Several hypotheses have been proposed to explain this phenomenon, including negative frequency-dependent selection, competition between siblings, genetic and ecological factors. Recent studies suggest that these different factors can act together to promote the fixation of sexual reproduction in populations.

Summary: Microgeographical adaptation occurs when directional selection persists despite gene flow. This study investigates the patterns of genomic divergence in four European and Mediterranean conifers with different life-history traits and ecological requirements. The results show that selection is strong in all species but affects different loci in each. Within-population diversity at microgeographical scales is likely to be a reservoir of adaptive potential.

Summary: The study of eco-evolutionary dynamics is gaining interest in the context of global change. However, many studies overlook interindividual interactions, which are central to selective values. Demo-genetic agent-based models (DG-ABMs) simulate these interactions and consider the feedback loop between ecological and evolutionary processes. DG-ABMs are particularly relevant for exploring fundamental questions in evolutionary ecology and evaluating the costs and benefits of management strategies.

Summary: Meiosis and syngamy generate an alternation between two ploidy stages, but the timing of these two processes varies widely across taxa, thereby generating life cycle diversity. One hypothesis suggests that life cycles with long-lived haploid stages are correlated with selfing, asexual reproduction, or both. Further investigations of algal life cycles will likely reveal the processes underlying the maintenance of sexual reproduction more broadly across eukaryotes, but more studies of natural populations are required.

Summary: Adaptation in natural populations can lead to rapid changes in phenotype and genotype frequencies over a few generations. A new ABC framework is proposed to understand the genetic and demographic changes during rapid adaptation. The framework demonstrates high accuracy in both model and parameter estimations and is applied to empirical data of a pathogen population. The inferred values are consistent with empirical knowledge, suggesting the potential of this framework in studying rapid adaptation.

Summary: Biological production systems and conservation programs should consider the evolutionary processes. A study using an individual-based demo-genetic modelling approach found that tree thinning, genetic evolution, and forest stand dynamics are interconnected. The evolutionary rates predicted by the model fit within the range of empirical estimates. Thinning regimes have a drastic long-term effect on evolutionary rate, potentially reaching 84% reduction.

Summary: Partial clonality and haplodiplontic life cycles structurally constrain the reshuffling of genetic diversity and its dynamics in populations, impacting the distribution of population genetic indices. Haplodiplontic life cycles affect effective population sizes and allow the evolution of two temporal genetic pools in sympatry, while partial clonality acts as a homogenizing force between these pools. The combined effects of proportion of haploids, rate of clonality, and the relative strength of mutation versus genetic drift impact the distributions of population genetic indices, making it challenging to apply knowledge from diploid or haploid species.

Summary: Partially clonality is a common reproductive mode found in different eukaryotic lineages, but often ignored in population genetic theory. Haplodiplontic organisms have unique life cycles, and the population genetic consequences of partial clonality in these organisms impact the distribution of genetic indices. Studies have shown similar patterns between empirical data and theoretical expectations, highlighting the importance of considering partial clonality in population genetics research for haplodiplontic taxa.
