Summary: This study evaluated the utility of four candidate DNA barcoding regions in seven genera of Gramineae. It found that matK and ITS showed the highest discriminatory power, while rbcL and trnL-F were less effective. The study also demonstrated the feasibility of establishing a technical system for rapid and reliable identification of these seven genera, and provided crucial reference for analyzing the genetic diversity of grass germplasm resources.

Summary: The study compares the effectiveness of traditional morphological methods and DNA barcoding methods in studying diatom communities. The results show significant differences in the compositional variation of diatom metacommunities between the two approaches. Biases affecting the molecular approach may include incomplete reference databases and bioinformatics processing, while biases affecting the morphological method may be limited counting effort and the presence of cryptic species. Additionally, variation in diatom community composition is strongly related to the environmental template, but not significantly related to geographical distances.

Summary: The identification of tube-forming species in the genus Ulva is often problematic due to insufficient genetic and morphological data. A new species, Ulva capillata, was identified and described based on molecular and morphological evidence, highlighting the importance of molecular investigation for accurate species identification in this genus.

Summary: The Gracilariaceae family consists of 242 mainly tropical species, with some having economic value for food and pharmaceutical industries. Through morphological and molecular analyses, 25 specific entities occurring on the Brazilian coast have been identified, including four new species yet to be described. The study highlights spermatangial arrangements and thallus morphology as important characters for species and genera delimitation.

Summary: The study evaluated the efficiency of four genetic markers in barcoding diatoms isolated from China, showing that multiple genetic markers can clearly differentiate most species and reveal potential cryptic species. COI, rbcL, and LSU sequences demonstrated high taxonomic resolution at the species level, while potential identification errors were found in public diatom sequences. Phylogenetic and character-based analysis provided consistent species identification and clearer species discrimination compared to the distance-based method.

Summary: This study proposes a DNA-based method to accurately identify the numerous species within the diverse Origanum genus. The analysis of chloroplast genes and a non-coding sequence showed that rbcL and psbA-trnH were most effective in identifying the genus, species, and subspecies. Combining multiple sequences improved accuracy.

Summary: Boeckella originated on the Gondwanan supercontinent, diversifying and spreading to Australasia and South America. Populations in the Antarctic region descended from South American ancestors, indicating that original Antarctic Gondwanan lineages did not survive the Quaternary ice ages. The species accumulation rate of Boeckella has been decreasing since the early Eocene, possibly due to cooling trends during the Cenozoic era.

Summary: A new method for determining the heterozygosity of licorice seed mixture was proposed, based on high-throughput full-length multiple DNA barcodes. The results showed that this method successfully identified the complete gradients of complex mixed samples. This method provides a brilliant and feasible way for evaluating the heterozygosity of licorice seeds.

Summary: Taxonomic studies based on molecular markers led to the description of a new species, Hypnea pseudomusciformis, which accommodates three morphologically divergent species with identical DNA barcode sequences found on the coast of Brazil. Further phylogeographic studies showed that H. pseudomusciformis is divided into three distinct haplotype groups related to different floristic provinces along the Brazilian coast.

Summary: DNA sequence analysis reveals that the current classification of Gelidium is not monophyletic, with three distinctive lineages. A new genus, Gelidiorariphycus, is described to accommodate one of these lineages. The species in this genus have similar morphologies and primarily grow on shallow subtidal rocky shores.
