Eucommia ulmoides, a significant medicinal and industrial plant endemic to China, has been the subject of various genomic studies due to its unique properties and evolutionary significance. This study focuses on the characterization of the chloroplast genome structure of E. ulmoides. The complete chloroplast genome of E. ulmoides was sequenced and analyzed, revealing a typical quadripartite structure with a total length of 163 586 bp, including a large single-copy region, a small single-copy region, and two inverted repeat regions. The genome contains 135 genes, comprising 89 protein-coding genes, 38 transfer RNA genes, and 8 ribosomal RNA genes. Comparative genomic analysis indicated high structural consistency and size variation due to DNA repeat variations. Phylogenetic analysis confirmed the close relationship between E. ulmoides and Aucuba japonica. This comprehensive characterization provides valuable insights into the genetic makeup and evolutionary history of E. ulmoides, facilitating future conservation and utilization efforts.
