The family Lauraceae possesses ca. 50 genera and 2,500-3,000 species that are distributed in the pantropics. Only half of were represented previously published plastome phylogenies because difficulty obtaining research materials. Plastomes Hypodaphnideae Mezilaurus group, two lineages with unusual phylogenetic positions, have not been reported thus limit our full understanding on evolution family. Herbariomics, promoted by next generation sequencing technology, can make use herbarium specimens, provides opportunities to fill sampling gap.

Abstract Background The ephemeral flora of northern Xinjiang, China, plays an important role in the desert ecosystems. However, evolutionary history this remains unclear. To gain new insights into its origin and dynamics, we comprehensively sampled plants Brassicaceae, one essential plant groups flora. Results We reconstructed a phylogenetic tree using plastid genomes estimated their divergence times. Our results indicate that species began to colonize arid areas north Xinjiang during Early Miocene there was greater dispersal from surrounding community Middle Late Miocene, contrast or Pliocene periods. Conclusions findings, together with previous studies, suggest originated assembly became rapid onwards, possibly attributable global climate changes regional geological events.

Abstract The family Primulaceae s.l. is estimated to comprise approximately 60 genera and 2600 species worldwide. Although extensive research has been conducted on the its subfamily boundaries, there a lack of systematic studies utilizing complete plastid genome data, leading uncertainties in phylogenetic positions certain key taxa, such as Stimpsonia . In this study, genomic data were collected from 67 accessions representing four subfamilies 28 within family. Phylogenetic trees constructed using coalescent concatenated approaches elucidate evolutionary history By employing comprehensive dataset genomes all subfamilies, robust framework for was established. Contentious relationships identified at early stages divergence Primula among Cyclamen relatives, probably due rapid diversification. Our support idea that sister remainder Primuloideae, contrast with placement Myrsinoideae based nuclear data. A cytonuclear discordance position also detected Aegiceras corniculatum time estimates study align previous findings, indicating significant diversification events during Eocene Oligocene epochs. These timeframes coincide major geological climatic changes, which likely have influenced distribution Primulaceae. results underscore complex lay groundwork future aimed unraveling intricate dynamics

Camphora Fabr. is a genus in the family Lauraceae, comprising over 20 tropical and subtropical tree species. Since genera Cinnamomum Schaeff. were described, there has been long-lasting controversy regarding phylogenetic relationships among taxa both genera. In particular, inferences derived from plastid data remain debated, with varying hypotheses proposed occasional disputes concerning monophyly of taxa. To further investigate relationships, We analyzed plastomes nuclear ribosomal cistron sequences (nrDNA) 22 taxa, 15 13 representative related The range 152,745 to 154,190 bp, GC content 39.1% 39.2%. A total 128 genes identified plastomes, including 84 protein-coding genes, 8 rRNA 36 tRNA genes. 1130 SSR loci detected Camphora, A/T base repeats looked like most common. Comparative analyses revealed that exhibit high similarity overall structure. ycf1, ycf2, trnK (UUU), psbJ-psbL, ccsA-ndhD as candidate DNA barcodes for these Plastome analysis not monophyletic, whereas nrDNA dataset supported Camphora. propose intergeneric hybridization may underlie observed discordance between we recommend enhanced taxonomic sampling precise species identification improve resolution accuracy.

Background. This study is aimed at effectively investigating the role of coagulation factor II thrombin receptor like 2 (F2RL2) in myocardial infarction (MI) as well upstream regulatory miRNA and lncRNA. Methods. Regulatory genes F2RL2 were analyzed using StarBase verified by dual-luciferase reporter assay. The MI mouse model was established. left ventricular ejection fraction (EF) fractional shortening (FS) examined echocardiography. infarct area, pathological changes, cell apoptosis tissue evaluated triphenyltetrazolium chloride Evans blue, hematoxylin-eosin, TUNEL staining assays.
