摘要

Typhonium flagelliforme, an Indonesian endemic medicinal species from the Araceae family, has attracted growing scientific interest due to its notable anticancer potential. Recognized as a valuable genetic resource, this species offers promising prospects for future breeding and biotechnological applications. In this study, we report the first complete chloroplast (cp.) genome of T. flagelliforme. The chloroplast genome spans 167,120 bp and displays the canonical quadripartite organization, comprising a large single-copy (LSC) region of 89,453 bp, a small single-copy (SSC) region of 14,524 bp, and two inverted repeats (IRs) of 31,573 bp each. Genome annotation recovered 130 genes, including 87 protein-coding genes, 8 rRNA genes, and 35 tRNA genes. We identified 102 simple sequence repeats (SSRs), with mononucleotide repeats representing the majority (86%). Phylogenetic reconstruction highlights the genetic coherence of T. flagelliforme while clearly separating it from other Typhonium species, providing further resolution of evolutionary relationships within the Araceae. Collectively, these genomic insights not only enhance our understanding of T. flagelliforme’s evolutionary context but also contribute foundational knowledge for future taxonomic, phylogenetic, and conservation studies within the genus.
