Article Synopsis
- Orchids are diverse species with unique floral structures, making them significant both economically and culturally.
- The newly updated OrchidBase 6.0 includes whole-genome sequences and transcriptomes for three Cymbidium species, enhancing research resources for the plant science community.
- New analytical methods were created to improve orchid genome analysis, supporting the growing needs for data management and research in orchid genetics.
Article Synopsis
- This study investigates the mitogenomes of two important tree species, Castanopsis carlesii and Castanea henryi, for the first time, highlighting their ecological and economic significance.
- The research found that C. carlesii's mtDNA has a unique multi-branched structure, while Ca. henryi's mtDNA consists of independent molecules, with the significant variation in their sizes attributed to dispersed repeats.
- The findings contribute to a better understanding of mitochondrial genome evolution in the Fagaceae family, paving the way for further exploration of key traits such as cell respiration and disease resistance.
, a genus of the subtribe Aeridinae of Orchidaceae, comprises ca. 40 species. Members of exhibit unique morphological characteristics and represent a valuable ornamental orchid genus.

- The study focuses on Darwin's orchid, a diverse genus within the Angraecinae subfamily of orchids, and reports on four complete plastomes, highlighting their structural characteristics and genetic content.
- The plastomes were found to have a typical quadripartite structure, containing 120 genes, and exhibited a high level of conservation in codon usage and strong evidence of purifying selection.
- The research identified key regions of nucleotide diversity and established phylogenetic relationships, confirming the genus as a distinct monophyletic group, which supports future investigations in molecular identification and plastome evolution.
Article Synopsis
- Researchers sequenced and assembled seven complete plastomes of the rare orchid genus Chiloschista to study their characteristics, phylogenetic relationships, and develop barcoding methods.
- The Chiloschista plastomes feature a typical quadripartite structure and contain 120 genes; unique mutations and hotspots for barcoding were identified, with the ycf1 gene showing the most potential for species discrimination.
- Phylogenetic analysis confirmed that Chiloschista is monophyletic and positioned it within the Aeridinae subtribe, revealing three major clades among the species analyzed, all supported by strong empirical data.
Article Synopsis
- The Elsholtzieae tribe, part of the mint family, consists of about 7 genera and 70 species valued for their medicinal, culinary, and ornamental uses, yet lacks extensive molecular research.
- This study utilized high-throughput sequencing to assemble and analyze two plastomes, revealing a quadripartite structure with 132 genes, including 85 protein-coding genes and highlighting variations that may serve as molecular markers for species identification.
- Phylogenetic analysis showed that four genera are monophyletic, which enhances understanding of their relationships and provides a basis for future studies and applications of Elsholtzieae resources.
Article Synopsis
- The text discusses the genus of orchids, highlighting its diverse colors and shapes and its value as an ornamental species.
- It presents new phylogenomic data derived from plastome sequences of seven orchid species to better understand their evolutionary relationships.
- Findings indicate that the genus is monophyletic with recognizable genetic features, providing valuable insights for classification and studies of evolution in this plant group.
Goodyerinae are one of phylogenetically unresolved groups of Orchidaceae. The lack of resolution achieved through the analyses of previous molecular sequences from one or a few markers has long confounded phylogenetic estimation and generic delimitation. Here, we present large-scale phylogenomic data to compare the plastome structure of the two main clades (Goodyera and Cheirostylis) in this subtribe and further adopt two strategies, combining plastid coding sequences and the whole plastome, to investigate phylogenetic relationships.

The plastome was 147,888 bp in length with 85,899 bp of the large single-copy (LSC) region, 11,055 bp of the small single-copy (SSC) region and 25,467 bp of the invert repeats (IR) regions. The genome contained 120 genes, including 74 protein-coding genes, 38 tRNA genes, and 8 rRNA genes.
