Phylogenetic analyses based on three DNA barcode markers (ITS, matK rpl20-rps12) indicated that two accessions were grouped together (PP=1.00,...

Abstract The genus Corydalis , with ca. 530 species, has long been considered taxonomically challenging because of its great variability. Previous molecular analyses, based on a few markers and incomplete taxonomic sampling, were clearly inadequate to delimit sections subgenera. We have performed phylogenetic analyses related taxa, using 65 shared protein‐coding plastid genes from 313 accessions (including 280 samples 226 species ) 152 universal low‐copy nuclear 296 271 covering all 42...

Abstract Aims The tropical niche conservatism (TNC) hypothesis and the out of tropics (OTT) propose mechanisms generating patterns species diversity across warm‐to‐cold thermal gradients at large spatial scales. These two hypotheses both integrate ecological biogeography‐related evolutionary factors, but they predict opposite for phylogenetic structure. Mount Namjagbarwa possesses one longest elevational flowering plant in world. We aim to analyse structure plants this mountain, investigate...

Sinosenecio B. Nordenstam (Asteraceae) currently comprises 44 species. To investigate the interspecific relationship, several chloroplast markers, including ndhC-trnV, rpl32-trnL, matK, and rbcL, are used to analyze phylogeny of Sinosenecio. However, genomes this genus have not been thoroughly investigated. We sequenced assembled albonervius genome for first time. A detailed comparative analysis was performed in study using previously reported three species.The results showed that four...

Evolutionary radiations have intrigued biologists for more than a century, yet our understanding of the drivers radiating diversification is still limited. We investigate roles environmental and species-intrinsic factors in driving rapid radiation Saussurea (Asteraceae) by deploying number palaeoenvironment-, diversity- trait-dependent models, as well ecological distribution data. show that three main clades began to diversify Miocene almost simultaneously, with increasing rates (DRs)...

Biogeographic regionalization can help to better understand diversity in biogeography, conservation, and macroecology. Historical schemes typically focus on species distributions, often rarely considering the rich context that phylogeographic information provide. We investigated whether data could delineate floristic regions Qinghai-Tibet Plateau (QTP)-Hengduan Mountains (HDM) region by analyzing structure herb Parasyncalathium souliei (Asteraceae). sequenced plastid psbA-trnH trnL-rpl32...

Abstract Background Dactylicapnos is a climbing herbaceous vine, distributed from the Himalayas to southwestern China, and some of species have important medicinal values. However, chloroplast genomes never been investigated. In this study, seven covering all three sections one informal group were sequenced assembled, detailed comparative analyses genome structure provided for first time. Results The results showed that typical quadripartite with lengths 172,344 bp 176,370 bp, encoding total...

Abstract Aim Biodiversity hotspots are regions with the highest species richness, and most threatened species. Previous studies have shown that extinction risk may be more related to evolutionary history than species' traits. However, there is a knowledge gap on relationship between in biodiversity hotspots. Here, we link for flowering plants (angiosperms) global Location Global Methods We calculated historical measures (family family age, diversification rate ratio of crown age stem age)...

The flora of northern China forms the main part Sino-Japanese floristic region and is located in a south-north vegetative transect East Asia. Phylogeographic studies have demonstrated that an arid belt this has promoted divergence plants However, little known about how are restricted to respond climatic oscillation environmental change. Here, we used genomic-level data Myripnois dioica across its distribution as representative reconstruct plant demographic history, examine local adaptation...

Abstract Mazaceae, a recently proposed family in the Lamiales, contains three genera; Mazus , Lancea and Dodartia yet systematic position circumscription of have not been fully confirmed. This paper reports on an expanded analysis that included most species all genera using five chloroplast DNA regions ( matK psbA‐trnH intergenic spacer, rbcL rps16 trnL‐F spacer) ITS nrDNA to determine phylogenetic placement Mazaceae as well intrageneric relationships within relatively large genus . The...

Recent advances in Learned Image Compression (LIC) utilize the powerful Masked Modeling (MIM) framework (e.g., MAE). However, random masking treats all patches equally, which could lead (i) missing critical information and (ii) poor robustness, since different may have contributions to image reconstruction. The principle experiment shows that patch-level inherent feature evaluation is highly correlated with quality of reconstructed image. Based on this key insight, we propose a simple mask...
