Summary: This study examines the systematic value of carpological traits in the taxonomically complex genus Valerianella. The results show that these traits are useful in classifying the genus at higher taxonomic ranks, but not at the species level for certain species pairs. Genetic data support the taxonomic classification at the sectional level, but reveal admixture for some species pairs. The study also describes a new section within the genus to accommodate a highly divergent species.

Summary: This study focused on the cultured cyanobacterial diversity in two geothermal environments of northern Costa Rica. It identified several potential new species within known genera, and suggested the presence of three possible new genera in their collection. The thermal springs of Miravalles and Las Lilas were found to be reservoirs of novel phylogeographic lineages of phototrophic microorganisms, indicating unique biodiversity in these environments.

Summary: We hypothesize that primary endosymbiosis, as one of the most consequential events in evolution, accelerates lineage divergence, which we refer to as the endosymbiotic ratchet. Recent research on the photosynthetic amoeba, Paulinella, supports our proposal and shows that effective population size plays a central role in post-endosymbiosis divergence. Isolated populations exploit different strategies and behaviors to minimize competition during the early, rapid evolutionary phase of organelle integration.

Summary: In this study, the complete chloroplast genomes of 16 Citrus species were analyzed, and several unique features were identified. The genus Citrus was subdivided into seven subgenera based on the analysis. These findings have important implications for the identification, taxonomy, use, and evolution of Citrus species.

Summary: This study analyzed 50 complete plastomes of 46 Lysimachia species to identify their structure features and hypervariable loci. Thirteen highly variable regions were identified and certain plastid markers were found to be under positive selection. The genomic data provided new insights into the interspecific relationships of Lysimachia, establishing a basis for further exploration of its taxonomy, phylogeny, and evolutionary history.

Summary: Our study focuses on the Dendrobium orchids, which have large morphological divergence and difficulties in species taxonomy. We assembled the complete mitogenomes of two Dendrobium species and compared them with other orchids. The results reveal extensive variations in repetitive and chloroplast-derived sequences in Dendrobium mitogenomes, and the intergenic content has undergone expansion during evolution. We also sequenced the mitogenomes of 26 Dendrobium species and reconstructed their phylogenetic relationships based on mitochondrial and plastid data. The mitochondrial phylogeny shows partial characteristics of the plastid phylogeny and provides new insights into the phylogenetic relationships of Dendrobium species.

Summary: The study utilized SCUB analysis to investigate codon usage bias in subg. Cerasus, revealing natural selection as the main influencing factor, with gene expression level and GC content also impacting the usage pattern. The findings showed a consistent codon usage pattern across the 36 species, highlighting the importance of locus mutations and no-preference codons in phylogenetic reconstruction within the subgenus.

Summary: This study investigates the diversity, phylogeny, and classification of the Eustigmataceae group within the Eustigmatophyceae. Through comprehensive analyses of hundreds of DNA sequences and plastid genomes, the researchers reveal the phylogenetic relationships within the Eustigmataceae group and confirm the presence of Chlorobotrys as a member of this group. Additionally, the study redefines the taxonomic name of this group and provides insights into the morphology and flagellar protein genes of Chlorobotryaceae members. Overall, this research provides a comprehensive understanding of one of the most diverse lineages of eustigmatophyte algae.

Summary: This study provides a comprehensive assessment of codon manipulation in Saxifragales plastid genes, showing a high preference for AT bases and AT-ending codons. Intrafamilial differences in codon bias were detected in three families. Selection was found to play a dominant role in codon usage bias in Saxifragales plastid genes, supported by ENC plots and neutrality analyses. The inferred phylogenetic affinities of Saxifragales were consistent with each other and enhance our understanding of the evolutionary processes in this order.

Summary: In this study, we assembled 18 chloroplast genomes of the genus Indigofera and analyzed their structure, diversity, and phylogenetic relationships. We identified candidate DNA barcodes for species identification and revealed the phylogenetic relationships and adaptive evolution of Indigofera. These findings provide important insights for future studies on species identification, delimitation, adaptive evolution, and phylogenetic relationships of the genus Indigofera.
