Summary: This study investigated the complete plastomes of 6 Calanthe and 2 Phaius species, revealing their structural characteristics. The results showed highly conserved plastomes among the species, with some non-coding regions having more sequence repeats important for DNA barcoding. Phylogenetic analysis revealed a paraphyletic relationship in the Calanthe group and confirmed the position of Phaius delavayi within the genus Calanthe.

Summary: The genus Phoebe (Lauraceae) is an ideal source of timber, but habitat destruction and deforestation have led to most species being endemic to China and facing extinction. Comparative chloroplast genome analysis revealed highly divergent regions and genes that have potential applications in phylogenetics and evolutionary analysis. Phylogenetic analysis showed that Chinese Phoebe species can be divided into three clades. This research contributes to the understanding and conservation of endangered Phoebe species.

Summary: The study sequenced chloroplast genomes of Zygophyllum and Peganum from China, revealing smaller cp genomes in Zygophyllum with similar structure and gene content, but some differences at the molecular level. Highly variable intergenic spacers and cpSSR markers were identified in Zygophyllum, providing insights for future research on genetic diversity and relationships. The phylogenetic analysis supported the division of Chinese Zygophyllum into herbaceous and shrubby clades and addressed taxonomic questions within the genus based on molecular and morphological evidence.
