Characteristics and phylogenetic analysis of the complete chloroplast genome of Vernonia volkameriifolia DC. 1836 (Asteraceae).

Vernonia volkameriifolia DC. 1836, is a woody shrub of the subfamily Vernonioideae within the family Asteraceae. The complete chloroplast genome of V. volkameriifolia spans 152,934 bp, comprising four subregions: a large single-copy region (84,035 bp), a small single-copy region (18,543 bp), and a pair of inverted repeats (25,178 bp). Within the chloroplast genome of V. volkameriifolia, 114 unique genes were identified, including 80 unique protein-encoding genes, four ribosomal RNA (rRNA) genes, and 30 transfer RNA (tRNA) genes. Phylogenetic analysis based on the complete chloroplast genome of six related taxa in the Vernonieae tribe indicates that V. volkameriifolia show closer relationships with Vernonia parishii and Strobocalyx arborea. The first chloroplast genome of V. volkameriifolia was reported in this work, contributing to the enrichment of genomic data for the genus Vernonia. [ABSTRACT FROM AUTHOR]
