Abstract The Qinghai–Tibet Plateau (QTP) sensu lato ( sl ) houses an exceptional species diversity in Asia. To develop a comprehensive understanding of this fascinating region, we reviewed recent progress from biogeographic, paleogeographic, paleontological and genomic research both plants animals the QTP . Numerous studies have been conducted to examine whether uplift triggered production rich there, Quaternary “unified ice sheet” eliminated on central plateau how high‐altitude developed extreme environment adaptations. Major disputes arose about first issue, mainly different circumscriptions related uplift, inaccurate dating molecular phylogenetic trees, non‐causal correlations between diversification. is spatially temporally heterogeneous, abundant fossils reported recently similarly support such asynchronous upheaval model across entire region. Available phylogeographic alpine suggested their glacial refugia , rejecting unified sheet during Last Glacial Maximum. Genomic evidence limited number has identified numerous candidate genes for adaptation. In future, more should be focused speciation adaptation mechanisms based cutting‐edge methods.

Tissue-specific and cis-regulatory changes underlie parallel, adaptive gene expression evolution in house mice

PLoS Genetics, Год журнала: 2024, Номер 20(2), С. e1010892 - e1010892

Опубликована: Фев. 2, 2024

Changes in gene regulation have long been appreciated as a driving force of adaptive evolution, however the relative contributions cis- and trans- acting changes to over short evolutionary timescales remain unclear. Instances recent, parallel phenotypic evolution provide an opportunity assess whether patterns are seen at level expression, contribution cis - trans early stages divergence. Here, we studied expression liver brown adipose tissue two wild-derived strains house mice that independently adapted cold, northern environments, compared them strain from warm, tropical environment. To investigate regulatory parents allele-specific F1 hybrids crosses between warm-adapted cold-adapted strains. First, found different showed both unique shared but proportion (i.e. parallelism) was greater than expected by chance. Second, discovered occurred largely tissue-specific -regulated genes, these genes were over-represented cases evolution. Finally, integrated data with scans for selection natural populations substantial parallelism under selection. Furthermore, outliers associated more chance; influenced phenotypes such body size, immune functioning, activity level. These results demonstrate cold environments driven -regulatory changes, providing insight into mechanisms earliest

Abstract Background A comprehensive analysis of gene expression profiling across tissues can provide necessary information for an in-depth understanding their biological functions. We performed a large-scale and generated high-resolution atlas the transcriptome in beef cattle. Results Our was from 135 bovine adult cattle, covering 51 tissue types major organ systems (e.g., muscular system, digestive immune reproductive system). Approximately 94.76% sequencing reads were successfully mapped to reference genome assembly ARS-UCD1.2. detected total 60,488 transcripts, 32% them not reported before. identified 2654 housekeeping genes (HKGs) 477 tissue-specific (TSGs) tissues. Using weighted co-expression network analysis, we obtained 24 modules with 237 hub (HUBGs). Functional enrichment showed that HKGs mainly maintain basic activities cells, while TSGs involved differentiation specific physiological processes. more conserved terms pattern as compared HUBGs among multiple species. Finally, subset differentially expressed (DEGs) between dairy cattle several functional pathways, which may be production health traits. Conclusions providing valuable enhancing annotation. HKGs, TSGs, further contribute better biology evolution DEGs also fill knowledge gaps about differential regulation underlying economically important

The evolution of ancestral and species-specific adaptations in snowfinches at the Qinghai–Tibet Plateau

Proceedings of the National Academy of Sciences, Год журнала: 2021, Номер 118(13)

Опубликована: Март 22, 2021

Significance Harsh conditions in high elevations present strong stresses for organisms. Previous studies targeting phylogenetically distinct species revealed cases of diversified adaptations, but it remains largely unknown how common ancestry contributes to evolution similar adaptations. Our study based on a complex (snowfinches) living Qinghai–Tibet Plateau shows that ancestral snowfinches had phenotypically evolved larger body size and genetically an accelerated selection genes related development signaling. From this state adaptation three descendants have undergone independent adaptive processes response the differences selective pressures acting them. A striking example is DNA repair gene, DTL , which nonsynonymous substitutions evolving ancestor led different damage kinetics.

Опубликована: Фев. 24, 2022

Abstract Aim Mountains harbour a rich and non‐random cluster of species, yet knowledge the species' biological attributes that support their coexistence in montane community is limited. Here, we investigated association species occurrence on Tibetan Plateau with morphological, ecological or evolutionary constraints. Location (TP). Taxon Mammals birds. Methods We tested whether TP correlates constraints using spatial distribution, phylogeny, dispersal ability thermal niche property data for 1353 terrestrial vertebrates (383 mammals 970 birds). used standard (non‐phylogenetic) phylogenetic logistic regressions to elucidate relative contributions these explaining TP. assessed geographical patterns structures fitted linear mixed models explore underlying eco‐evolutionary forces. Results The exhibited higher cold tolerance, wider breadth rate evolution than non‐TP species. supported assumption were not random subset from pool, but structured jointly by environmental filtering limitation. While processes assemblages varied spatially among taxa, found stressful environments limited filtering, whereas limitation was more pronounced under favourable climatic conditions. Main conclusions Our study finds shape assemblage These findings provide significant insights into assembly other ecosystems Earth, especially those are sensitive global warming.
