Abstract

Philodendron hederaceum (Jacq.) Schott 1829, a species of the Araceae family, is a foliage plant of ornamental value. The complete chloroplast genome sequence of Philodendron hederaceum was obtained by the de novo assembly of NovaSeq 6000 (Illumina Co., San Diego, CA) paired-end short reads and Oxford Nanopore long reads. The complete chloroplast genome of P. hederaceum was 168,609 bp in length, with a large single-copy (LSC) region of 94,393 bp, a small single-copy (SSC) region of 25,774 bp, and a pair of identical inverted repeat regions (IRs) of 24,221 bp. The genome contained a total of 129 genes, including 85 protein-coding genes, 36 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. The phylogenetic analysis of P. hederaceum with 19 related species and two outgroup species revealed the closest taxonomical relationship with Philodendron lanceolatum in the Araceae family.

Photograph of Philodendron hederaceum (Jacq.) Schott 1829 (these photographs were taken by Jae Hwan Lee). The foliage of P. hederaceum exhibits heart-shape and glossy texture on cascading stems. Upper surface of leaves has medium to dark green color, while lower surface has medium green color. The primary lateral veins have 2–6 per side, and emerge from the midvein at an angle of 35° to 55°.

Chloroplast genome map of Philodendron hederaceum. Genes inside the circle are transcribed in a counterclockwise direction, and genes outside the circle are transcribed in a clockwise direction. The color of each gene represents its function. LSC, SSC, IRa, and IRb regions are indicated in this map.
