Article Synopsis
  • The Apiaceae family is the largest group of flowering plants in the Northern Hemisphere, but its conservation status and species distribution in Mongolia are not well understood.
  • This study aimed to assess the conservation status of Apiaceae species in Mongolia using IUCN criteria and to evaluate the diversity and richness of these species across the region.
  • The research found that 27 Apiaceae species were threatened, including critically endangered and vulnerable species, while also providing detailed distribution maps and analyzing species richness across 715 grid cells in Mongolia.

Phylogenomic conflicts are widespread among genomic data, with most previous studies primarily focusing on nuclear datasets instead of organellar genomes. In this study, we investigate phylogenetic conflict analyses within and between plastid and mitochondrial genomes using Potentilla as a case study. We generated three plastid datasets (coding, noncoding, and all-region) and one mitochondrial dataset (coding regions) to infer phylogenies based on concatenated and multispecies coalescent (MSC) methods.

Plants classified as Near Threatened (NT) are at high risk of becoming threatened because of anthropogenic interference and climate change. Especially in conservation efforts, such species have however long been overlooked. Here, we obtained 98,419 precise occurrence points for 2442 NT plants in China, and used species richness, species complementarity, and weighted endemism that consider all, endemic and narrow-ranged species in order to identify the diversity hotspots of NT plants.

Article Synopsis
  • Drylands make up 41% of the Earth's land area and are at significant risk of degradation, yet their historical development remains poorly understood; Zygophyllaceae serves as a key example for studying the evolution of dryland plants.
  • Researchers combined various methods, including phylogenetics and biogeography, to analyze the growth patterns of Zygophyllaceae, finding that it spread across continents during the mid-late Miocene, around 15-10 million years ago.
  • The findings indicate that the formation of global dryland floras occurred nearly simultaneously during this period, likely influenced by global cooling and climate changes.

East Asia is characterized by high levels of species diversity and endemism. However, the biogeographical patterns and processes underlying the distribution of biodiversity within the area are still poorly known. In this study, we used plastid (matK, trnL-F, and trnH-psbA) and nuclear (ITS) DNA sequences to investigate the historical biogeography of Dichocarpum (Ranunculaceae), an eastern Asian endemic genus throughout warm-temperate and subtropical forests of the area.

The rise of angiosperms has been regarded as a trigger for the Cretaceous revolution of terrestrial ecosystems. However, the timeframe of the rise angiosperm-dominated herbaceous floras (ADHFs) is lacking. Here, we used the buttercup family (Ranunculaceae) as a proxy to provide insights into the rise of ADHFs.

Impatiens L. is one of the largest angiosperm genera, containing over 1000 species, and is notorious for its taxonomic difficulty. Here, we present, to our knowledge, the most comprehensive phylogenetic analysis of the genus to date based on a total evidence approach.

Background: The species-rich genus Impatiens is mainly distributed throughout much of tropical Africa, India, southwest Asia, southern China and Japan. There are more than 270 species recorded in China, most of which are restricted to the southwest. An unknown species of Impatiens was collected from Yunnan, southwest China.

The Asian interior arid zone is the largest desert landform system in the Northern Hemisphere, and has high biodiversity. Little is currently known about the evolutionary history of its biota. In this study, we used Zygophyllum, an important and characteristic component of the Asian interior arid zone, to provide new insights into the evolution of this biota.
