Chloroplast genome characteristics and phylogenetic analysis of Trevesia palmata (Roxburgh ex Lindley) Visiani (Araliaceae)

Trevesia palmata (Roxburgh ex Lindley) Visiani 1842 is a distinctive and visually striking plant species belonging to the family Araliaceae. Commonly known as the ‘Snowflake Aralia’ or ‘Spider Leaf Tree’, it is native to the subtropical and tropical regions of Southeast Asia. This study exhibits a complete chloroplast genome of T. palmata, alongside a phylogenetic analysis involving 23 additional species from Araliaceae. The chloroplast genome has a length of 156,541 bp and an overall GC content of 37.9%, which is structurally composed of a large single-copy (LSC) region (86,460 bp), a small single-copy (SSC) region (18,119 bp), and a pair of inverted repeat (IRs) regions (25,981 bp). At the gene level, this chloroplast genome harbors a total of 133 genes, comprising of 88 protein-coding genes, 37 tRNA genes and 8 rRNA genes. The phylogram showed that T. palmata shares a close evolutionary affinity with Brassaiopsis and Eleutherococcus. The chloroplast genome annotated and displayed below will lay a favorable foundation for the species relationship identification and evolutionary research of Trevesia.
