Heterogeneous occurrence of evergreen broad-leaved forests in East Asia: Evidence from plant fossils

Plant Diversity, Год журнала: 2024, Номер unknown

Evergreen broad-leaved forests (EBLFs) are widely distributed in East Asia and play a vital role ecosystem stability. The occurrence of these has been subject debate across various disciplines. In this study, we explored the Asian EBLFs from paleobotanical perspective. By collecting plant fossils four regions Asia, have established evolutionary history EBLFs. Through floral similarity analysis paleoclimatic reconstruction, revealed diverse spatio-temporal pattern for Asia. earliest southern China can be traced back to middle Eocene, followed by southwestern during late Eocene-early Oligocene. Subsequently, emerged Japan early Oligocene eventually appeared central-eastern around Miocene. Paleoclimate simulation results suggest that precipitation wettest quarter (PWetQ, mm) exceeding 600 mm is crucial Furthermore, heterogeneous closely associated with evolution Monsoon. This study provides new insights into

Genome‐wide patterns of local adaptation associated with transposable elements in Tetrastigma hemsleyanum (Vitaceae)

New Phytologist, Год журнала: 2025, Номер unknown

Summary The mobility of transposable elements (TEs) partly drives genome evolution, potentially leading to either adaptive or deleterious effects. However, it remains far from clear whether and how TEs contribute adaptation changing environments, especially in plants. We analyzed whole‐genome sequencing data 29 ecologically diverse Tetrastigma hemsleyanum populations infer the species' demographic history its impact on TE polymorphisms. Integrated selective sweep genome–environment association (GEA) approaches were employed examine contribution environmental adaptation. ancestor T. diverged during late Miocene/Pliocene, forming two lineages that further split into four sublineages. These (sub)lineages underwent periodic population declines recoveries late‐Pleistocene climatic oscillations, with most polymorphic transposing last glacial period. A small fraction these (0.033–0.40%) showed signatures positive selection, while a broader subset (0.081–0.76%) correlated significantly variables. Notably, selected climate‐linked polymorphisms preferentially retained gene‐poor regions frequently linked genes involved organ development stress/defense response. Our findings demonstrate played key regulatory role T . 's response change, underscoring their importance better understanding genomic mechanisms underlying

Niche Evolution and Conservation of a Chinese Endemic Genus Sinojackia (Styracaceae)

Biology, Год журнала: 2024, Номер 13(12), С. 1085 - 1085

Опубликована: Дек. 22, 2024

Climate change and human activities are expected to have a profound impact on the distribution of species, especially for narrowly distributed species. Sinojackia is endemically in China, all species listed under Chinese protected wild Here, we reconstructed phylogeny estimated divergence time based whole plastomes, conducted niche evolution, predicted potential habitat area from LGM future. Our results strongly supported monophyly plastomes. This genus originated middle Miocene diversified since late Miocene. The aridity index was highest significant factor its evolution rate increased slowly divergence. precipitation warmest quarter main environmental variable affecting LGM, while footprint near-current era 2081–2100. Compared current Sinojackia, highly suitable contracted but expanded during study provides areas situ conservation Sinojackia.
