Summary: This study reported three new Heteroplexis chloroplast genomes, which showed high conservation and provided valuable genetic resources for future studies on the taxonomy, phylogeny, and evolution of the Aster genus. Phylogenetic analyses did not support the monophyly of the Heteroplexis genus, suggesting that the five species might be subsumed into the Aster genus.

Summary: In this study, the complete chloroplast genomes of twelve Paraboea species were sequenced and analyzed, revealing the genomic structure and composition, as well as potential molecular markers. In the phylogenetic tree, all Paraboea species formed a distinct clade, confirming their monophyly. Additionally, genes related to photosynthesis and protein synthesis were found to play crucial roles in the adaptability of Paraboea to diverse karst environments.

Summary: Eruca sativa is an important edible vegetable with potential medicinal properties due to antibacterial activity of its seed oil. The complete chloroplast genome of E. sativa shares similarities with other Brassicaceae species, and protein-coding genes show purifying selection pressure, suggesting evolutionary closeness with important Brassica species. This may allow transfer of beneficial alleles from E. sativa to improve other Brassica species.

Summary: The study analyzed the plastomes of ten Ficus species, revealing their similar genome structure but with variation in inverted repeat regions. The comparative analysis showed low sequence variability and suggested eight variable regions as potential molecular markers. Phylogenetic analysis grouped the species into three clades based on subgenera, supporting the Berg classification system. The study contributes to understanding genetic diversity and species evolution of Ficus, providing valuable information for taxonomic and phylogenetic studies.

Summary: In this study, the chloroplast genomes of 29 tomato germplasms were sequenced and analyzed to compare and understand their phylogenetic relationships. The analysis revealed highly conserved characteristics among the cp genomes, including structure, gene and intron number, inverted repeat regions, and repeat sequences. Candidate SNP markers for future studies were selected based on highly polymorphic SNP loci. The phylogenetic tree showed that the cp genomes of tomatoes were clustered into two major clades, with S. pimpinellifolium and S. lycopersicum showing a close genetic relationship. Only rps15 gene exhibited the highest average K-A/K-S ratio in the analysis of adaptive evolution, indicating strong positive selection. This study provides valuable information for further research on phylogenetic relationships, evolution, germplasm identification, and molecular marker-assisted selection breeding of tomato.

Summary: In this study, the complete chloroplast genomes of nine Pimpinella species from China were assembled and analyzed using next generation sequencing. Significant differences were found in genome size, gene number, IR boundary, and sequence identity among the Pimpinella species. The non-monophyly of the Pimpinella species and the distant relationship between the Pimpinella species and Pimpinelleae were confirmed. This study provides a foundation for future phylogenetic and taxonomic studies of the genus Pimpinella.
