Tissue regeneration is a multi-step process mediated by diverse cellular hierarchies and states that are also implicated in tissue dysfunction pathogenesis. Here we leveraged single-cell RNA sequencing combination with vivo lineage tracing organoid models to finely map the trajectories of alveolar-lineage cells during injury repair lung regeneration. We identified distinct AT2-lineage population, damage-associated transient progenitors (DATPs), arises alveolar found interstitial...

Evolution is typically thought to proceed through divergence of genes, proteins and ultimately phenotypes. However, similar traits might also evolve convergently in unrelated taxa owing selection pressures. Adaptive phenotypic convergence widespread nature, recent results from several genes have suggested that this phenomenon powerful enough drive recurrent evolution at the sequence level. Where homoplasious substitutions do occur these long been considered result neutral processes. studies...

Abstract The evolution of cetaceans, from their early transition to an aquatic lifestyle subsequent diversification, has been the subject numerous studies. However, although higher-level relationships among cetacean families have largely settled, several aspects systematics within these groups remain unresolved. Problematic clades include oceanic dolphins (37 spp.), which experienced a recent rapid radiation, and beaked whales (22 not investigated in detail using nuclear loci. combined...

Abstract Recent phylogenomic analyses have suggested tunicates instead of cephalochordates as the closest living relatives vertebrates. In direct contradiction with long accepted view Euchordates, this new phylogenetic hypothesis for chordate evolution has been object some skepticism. We assembled an expanded dataset focused on deuterostomes. Maximum‐likelihood using standard models and Bayesian CAT site‐heterogeneous mixture model amino‐acid replacement both provided unequivocal support...

Abstract Background Tunicates have been recently revealed to be the closest living relatives of vertebrates. Yet, with more than 2500 described species, details their evolutionary history are still obscure. From a molecular point view, tunicate phylogenetic relationships mostly studied based on analyses 18S rRNA sequences, which indicate several major clades at odds traditional class-level arrangements. Nonetheless, substantial uncertainty remains about and taxonomic status key groups such...

Abstract Next‐generation sequencing (NGS) technologies offer the opportunity for population genomic study of non‐model organisms sampled in wild. The transcriptome is a convenient and popular target such purposes. However, designing genetic markers from NGS data requires assembling gene‐coding sequences out short reads. This complex task owing to gene duplications, polymorphism, alternative splicing transcription noise. Typical programmes return thousands predicted contigs, whose connection...

Phylogenomics has revealed the existence of fast-evolving animal phyla in which amino acid substitution rate, averaged across many proteins, is consistently higher than other lineages. The reasons for such differences proteome-wide evolutionary rates are still unknown, largely because only a handful species offer within-species genomic data from molecular processes can be deduced. In this study, we use next-generation sequencing technologies and individual whole-transcriptome to gather...

Abstract Next Generation Sequencing technologies (NGS) are rapidly invading many evolutionary and ecological fields, such as phylogenomics, molecular evolution, population genomics ecology. Among the potential targets of NGS is transcriptome sequencing, a fast relatively cheap way to generate massive amounts coding sequence data, offering promising perspectives for analysis diversity in wild. A number ecology research groups therefore may switch from DNA‐based RNA‐based typing near future....

During their evolutionary radiation, mammals have colonized diverse habitats. Arguably the subterranean niche is most inhospitable of these, characterized by reduced oxygen, elevated carbon dioxide, absence light, scarcity food, and a substrate that energetically costly to burrow through. Of all lineages transitioned niche, African mole-rats are one successful. Much ecological success can be attributed diet plant storage organs, which has allowed them colonize climatically varied habitats...

Abstract Dietary adaptation is a major feature of phenotypic and ecological diversification, yet the genetic basis dietary shifts poorly understood. Among mammals, Neotropical leaf-nosed bats (family Phyllostomidae) show unmatched diversity in diet; from putative insectivorous ancestor, phyllostomids have radiated to specialize on diverse food sources including blood, nectar, fruit. To assess whether diversification this group was accompanied by molecular adaptations for changing metabolic...

The transition to an aquatic lifestyle in cetaceans (whales and dolphins) resulted a radical transformation their sensory systems. Toothed whales acquired specialized high-frequency hearing tied the evolution of echolocation, whereas baleen evolved low-frequency hearing. More generally, all show adaptations for seeing underwater. To determine extent which these phenotypic changes have been driven by molecular adaptation, we performed large-scale targeted sequence capture 179 genes across...
