摘要

Garcinia indica (Thouars) Choisy is a threatened and endemic medicinal tree species from the Western Ghats of India with significant pharmaceutical and industrial applications. The fruit rind and seeds, commonly traded as 'Kokum,' have high trade value. The current study aimed to assemble and analyze the complete chloroplast (cp) genome of G. indica and perform comparative analysis with related Garcinia species. The cp genome of G. indica was assembled to a size of 156,891 bp, exhibiting a typical quadripartite structure. The large single-copy (LSC) and small single-copy (SSC) regions comprised 64.5% of the genome, spanning 85,580 and 17,181 bp, respectively. A pair of inverted repeats (IRA and IRB) accounted for the remaining 35.5%, each stretching by approximately 27,065 bp. The genome map revealed 126 unique genes, including 86 protein-coding, 32 tRNA, and eight rRNA genes. Phylogenetic analysis, using the complete cp genomes of ten Garcinia species, identified a distinct monophyletic clade, with G. indica showing a closer genetic affiliation with G. oblongifolia than with G. esculanta in a sub-clade. This study provides essential insights into the cp genome of G. indica and offers a valuable resource for future research on the genetic and agronomic traits of this medicinal species. In addition, phylogenetic analysis enhances our understanding of the evolutionary relationships among Garcinia species, with potential applications in conservation and breeding strategies for endemic trees.
