Nudix hydrolases are conserved enzymes ubiquitously present in all kingdoms of life. Recent research revealed that several involved terpenoid metabolism plants. In modern roses, RhNUDX1 is responsible for formation geraniol, a major compound rose scent. Nevertheless, this produced by monoterpene synthases many geraniol-producing As consequence, raised the question about origin function and NUDX1 gene evolution Rosaceae, wild roses or/and during domestication process. Here, we showed three...
Gynodioecy, the coexistence of hermaphrodites with females, often reflects conflicts between cytoplasmic male sterility (CMS) genes and nuclear restoring fertility. CMS is frequent in plants has been recently discovered one animal: freshwater snail, Physa acuta. In this system, was linked to a single divergent mitochondrial genome (D), devoid apparent restoration. Our study uncovers second, novel CMS-associated mitogenome (K) acuta, demonstrating an extraordinary acceleration molecular...
Abstract GC-biased gene conversion (gBGC) is a widespread evolutionary force associated with meiotic recombination that favours the accumulation of deleterious AT to GC substitutions in proteins, moving them away from their fitness optimum. In many mammals hotspots have rapid turnover, leading episodic gBGC, mutations stopping when hotspot dies. Selection therefore expected act repair damage caused by gBGC episodes through compensatory evolution. However, this process has never been studied...
The rate of molecular evolution varies widely among species. Life history traits (LHTs) have been proposed as a major driver these variations. However, the relative contribution each trait is poorly understood. Here, we test influence metabolic (MR), longevity, and generation time (GT) on nuclear mitochondrial synonymous substitution rates using group isopod species that made multiple independent transitions to subterranean environments. Subterranean repeatedly evolved lower MR, longer...
Abstract Transition to novel environments, such as groundwater colonization by surface organisms, provides an excellent research ground study phenotypic evolution. However, interspecific comparative studies on evolution life are few because of the challenge in assembling large ecological and molecular resources for species‐rich taxa comprised subterranean species. Here, we make available scientific community operational set working tools Asellidae, a family freshwater isopods containing...
In asexual animals, female meiosis is modified to produce diploid oocytes. If still involves recombination, this expected lead a rapid loss of heterozygosity, with adverse effects on fitness. Many asexuals, however, have heterozygous genome, the underlying mechanisms being most often unknown. Cytological and population genomic analyses in nematode Mesorhabditis belari revealed another case recombining highly genome-wide. We demonstrated that heterozygosity maintained despite recombination...
All organisms on Earth are exposed to low doses of natural radioactivity but some habitats more radioactive than others. Yet, documenting the influence evolution biodiversity is challenging. Here, we addressed whether living in naturally accumulate mutations across generations using 14 species waterlice subterranean with contrasted levels radioactivity. We found that mitochondrial and nuclear mutation rates a waterlouse species' genome increased average by 60% 30%, respectively, when factor...
Abstract Storing, managing and sharing the ever‐increasing amount of species occurrence data biological vouchers is a cornerstone biodiversity science. The convergence morphology‐ DNA‐based methods for delimitation has accentuated need optimizing laboratory workflow by generating new analytical processes, diversifying taxonomic reference systems identification protocols multiplying vouchers. Yet, information management dedicated to multi‐criteria species‐based research are rare or they have...
Abstract Inducible defences in response to predation risk are a well-known example of adaptive phenotypic plasticity. While inducible have been mainly studied within generation (within-generational plasticity), there is now clear evidence that the ancestral exposure can influence expressed by offspring, even if they not exposed themselves (transgenerational plasticity). The molecular mechanisms allowing transmission environmental information across generations still misunderstood. In this...

Many asexuals, however, have heterozygous genome, the underlying mechanisms being most often unknown. Cytological and population genomic analyses in nematode Mesorhabditis belari revealed another case recombining highly genome-wide. We demonstrated that heterozygosity maintained because recombinant...
