subsp. (Craib) T. C. Chen 1988, a member of the family, subfamily, and genus, has a rich history of traditional usage in Chinese medicine. Renowned for its analgesic properties, it is commonly employed for managing inflammation and pain. This study aimed to sequence the complete chloroplast genome of subsp. using Illumina paired-end sequencing data. The chloroplast genome spans 156,967 bp and consists of four main regions: the large single-copy (LSC) region (89,185 bp), the small single-copy (SSC) region (19,146 bp), and a pair of inverted repeats (IRs) (24,318 bp). The overall GC content of the chloroplast genome is 36.19%, with specific values of 33.99%, 29.79%, and 42.76% for the LSC, SSC, and IR regions, respectively. A total of 128 genes were annotated in the chloroplast genome, including 83 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis revealed that subsp. is closely related to , indicating a sister taxon relationship between the two species. This study significantly contributes to the chloroplast genomic resource for , laying the groundwork for future phylogenetic investigations within the genus.

The family Daphniphyllaceae has a single genus, and no relevant comparative phylogenetic study has been reported on it. To explore the phylogenetic relationships and organelle evolution mechanisms of Daphniphyllaceae species, we sequenced and assembled the chloroplast and mitochondrial genomes of Daphniphyllum macropodum. We also conducted comparative analyses of organelles in Daphniphyllaceae species in terms of genome structure, phylogenetic relationships, divergence times, RNA editing events, and evolutionary rates, etc.

Background: Assessing the current status and identifying the mechanisms threatening endangered plants are significant challenges and fundamental to biodiversity conservation, particularly for protecting Tertiary relict trees and plant species with extremely small populations (PSESP). Ulmus elongata (Ulmus, Ulmaceae) with high values for the ornamental application, is a Tertiary relict tree species and one of the members from PSESP in China. Currently, the wild populations of U.
