Article Synopsis
  • Acer is a complex genus with over 150 species, making it hard to identify them based solely on physical characteristics; thus, DNA barcoding using plastome and nrDNA sequences is examined for improved species identification.
  • In research involving 83 specimens from 55 species, plastomes showed the highest species discrimination power at 90.47%, while nrDNA also provided significant resolution but was affected by issues like hybridization and incomplete lineage sorting.
  • The study concludes that using both plastomes and nrDNA can enhance species resolution in Acer, but combining them is cautioned against due to conflicts arising from hybridization, indicating that hybridization plays a crucial role in Acer’s evolution.

Lomas formations or "fog oases" are islands of vegetation in the desert belt of the west coast of South America, with a unique vegetation composition among the world's deserts. However, plant diversity and conservation studies have long been neglected, and there exists a severe gap in plant DNA sequence information. To address the lack of DNA information, we conducted field collections and laboratory DNA sequencing to establish a DNA barcode reference library of Lomas plants from Peru.

Article Synopsis
  • The study analyzed and compared the mitochondrial genomes of three Primula species, revealing structural variations and a high level of nucleotide diversity within the group and between regions like the Mediterranean and Himalaya-Hengduan Mountains.
  • Findings indicated that RNA editing events, particularly in the atp6 gene, were significant and conserved across Ericales, helping clarify evolutionary relationships within the family and among Primula species.
  • The research highlighted potential factors influencing mitogenome size, such as the transfer of mitochondrial plastid sequences and foreign DNA, although these connections remained largely insignificant overall.

Background And Aims: Ongoing global warming is a challenge for humankind. A series of drastic climatic changes have been proven to have occurred throughout the Cenozoic based on a variety of geological evidence, which helps to better understand our planet's future climate. Notably, extant biomes have recorded drastic environmental shifts.

Background: Musaceae is an economically important family consisting of 70-80 species. Elucidation of the interspecific relationships of this family is essential for a more efficient conservation and utilization of genetic resources for banana improvement. However, the scarcity of herbarium specimens and quality molecular markers have limited our understanding of the phylogenetic relationships in wild species of Musaceae.

Background: The East Asian subtropical evergreen broad-leaved forests (EBLFs) harbor remarkable biodiversity. However, their historical assembly remains unclear. To gain new insights into the assembly of this biome, we generated a molecular phylogeny of one of its essential plant groups, the tribe Perseeae (Lauraceae).

Background: Gene tree discordance is common in phylogenetic analyses. Many phylogenetic studies have excluded non-coding regions of the plastome without evaluating their impact on tree topology. In general, plastid loci have often been treated as a single unit, and tree discordance among these loci has seldom been examined.

, a new orchid species belonging to section Cestichis from Guangxi, China is described and illustrated. It occurs in the karst limestone forest. The new species is morphologically similar to and , but can be readily distinguished by having narrowly oblong-falcate petals; flabellate-quadrate lip distinctly concave at base and emarginate at apex; conspicuously arcuate column with a pair of wedge-shaped wings.

What causes the disparity in biodiversity among regions is a fundamental question in biogeography, ecology, and evolutionary biology. Evolutionary and biogeographic processes (speciation, extinction, dispersal) directly determine species richness patterns, and can be studied using integrative phylogenetic approaches. However, the strikingly high richness of East Asia relative to other Northern Hemisphere regions remains poorly understood from this perspective.

Premise Of The Study: Microsatellite markers from Primula sikkimensis (Primulaceae) were developed for testing deep lineage divergence and speciation events.

Methods And Results: A total of 3112 microsatellites were identified from 61,755 unique reads though 454 pyrosequencing technology. Twenty-nine microsatellite loci were selected for PCR amplification and polymorphic analyses.

DNA barcoding of plants poses particular challenges, especially in differentiating, recently diverged taxa. The genus Gentiana (Gentianaceae) is a species-rich plant group which rapidly radiated in the Himalaya-Hengduan Mountains in China. In this study, we tested the core plant barcode (rbcL + matK) and three promising complementary barcodes (trnH-psbA, ITS and ITS2) in 30 Gentiana species across 6 sections using three methods (the genetic distance-based method, Best Close Match and tree-based method).
