Summary: In this study, the chloroplast genomes of three species of Paraphalaenopsis were reported and comprehensively analyzed. The genomes exhibited a quadripartite structure and varied in length from 147,311 bp to 149,240 bp. Unique genes including protein-coding genes, tRNA genes, and rRNA genes were identified in each genome. Six hypervariable regions were discovered as potential DNA molecular markers. Phylogenetic analysis indicated that Paraphalaenopsis is closely related to the Holcoglossum-Vanda clade within the Aeridinae subfamily. This study provides a foundation for future phylogenetic analysis of Aeridinae.

Summary: This study reports on the de novo assembled and annotated plastome of four species of Renanthera, a genus of orchids with significant ornamental value. The plastomes showed a typical quadripartite structure and nucleotide variations that could distinguish the species. Phylogenetic analyses revealed the relationship between Renanthera and other related genera. The genetic data obtained from this study can contribute to species identification and further research on the phylogenomics of Orchidaceae.

Summary: The chloroplast genomes of Phalaenopsis storbatiana and P. wilsonii were analyzed and compared, revealing their genetic relationship and taxonomic information. The study also found high sequence similarity in coding and non-coding regions among these two species and six related taxa, but different amplification in IR regions. Phylogenetic analysis confirmed the placement of P. storbatiana and P. wilsonii in tribe Vandeae of Epidendroideae, consistent with previous studies.

Summary: In this study, the complete chloroplast genomes of four Liparis species were sequenced and analyzed, and their phylogenetic relationships with related species were evaluated for the first time. Highly variable regions were identified as potential DNA markers for species identification and phylogenetic studies. The phylogenetic analysis based on chloroplast genome sequences supported the polyphyly of Liparis and its subdivision into three branches.

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: In this study, the NAC gene family in Dendrobium nobile was identified and analyzed. The results showed that these genes were unevenly distributed in the chromosomes and contained multiple stress responsive elements. Phylogenetic analysis indicated the close relation between the D. nobile NAC gene family and Dendrobium catenatum and Dendrobium chrysotoxum. QRT-PCR experiment verified the response mechanism of DnoNAC gene family under stress conditions.

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: This study sequenced and annotated the chloroplast genomes of two Blepharoglossum species, finding a relatively conserved gene content and arrangement, but still identifying a high number of SNPs and indels. Comparative analyses among six chloroplast genomes in Malaxidinae revealed significant sequence divergences in intergenic and coding regions. Phylogenetic analysis showed a close sister group relationship between Blepharoglossum and Oberonia.

Summary: The immature seeds of Dendrobium nobile develop resistance to freezing and long-term storage in a cryobank at the age of 6 months after pollination. The study found that there are differences in germination capacity, embryo viability, and staining characteristics at different stages of seed development. Immature seeds at 6 months old have a high germination rate in low-temperature conditions.
