Characterization of the complete chloroplast genome of Elaeocarpus glabripetalus (Elaeocarpaceae)

Abstract

Elaeocarpus glabripetalus Merr. is a notable species within the Elaeocarpus genus, particularly in the temperate regions of China. Distinguished by its cold resistance compared to other species, it encounters challenges in accurate identification, often prone to confusion with other related species. To address this issue, we present the complete chloroplast (cp) genome of E. glabripetalus in this study. The cp genome was 158,144 bp in length including two inverted repeats (IRs) of 27,388 bp, which were separated by large single copy (LSC) and small single copy (SSC) of 85,699 bp and 17,669 bp, respectively. The GC content was 37.1%. The genome encoded 135 functional genes, including 90 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. Phylogenetic analysis indicated that E. glabripetalus was clustered with other Elaeocarpus species and was a sister to E. sylvestris. This study provided the first report on the complete cp genome of E. glabripetalus, which is useful for further studies on species identification, germplasm conservation, and plant breeding in the Elaeocarpus genus and Elaeocarpaceae family.
