## Abstract

Passiflora tripartita var.
mollissima, known locally as poro-poro, is an important native fruit used in traditional Peruvian medicine with relevant agro-industrial and pharmaceutical potential for its antioxidant capacity for human health. However, to date, only a few genetic data are available, which limits exploring its genetic diversity and developing new genetic studies for its improvement. We report the poro-poro plastid genome to expand the knowledge of its molecular markers, evolutionary studies, molecular pathways, and conservation genetics. Total genomic DNA was extracted from fresh leaves (herbarium voucher: USM:MHN331530). The DNA was sequenced using Illumina Novaseq 6000 platform providing 163,451 bp in length, with a large single-copy region of 85,525 bp and a small single-copy region of 13,518 bp, separated by a pair of inverted repeat regions (IR) of 32,204 bp, and the overall GC content was 36.87%. The chloroplast genome contains 129 genes (112 genes were unique and 17 genes were found duplicated in each IR region), including 85 protein-coding genes, 37 transfer RNA-coding genes, seven ribosomal RNA-coding genes, and 14 genes with introns (12 genes with one intron and two genes with two introns). The phylogenetic tree reconstructed based on single-copy orthologous genes and maximum likelihood analysis demonstrates poro-poro is most closely related to
Passiflora menispermifolia and
Passiflora oerstedii. In summary, our study provides the basis for developing new molecular markers that constitutes a valuable resource for studying molecular evolution and domestication. It also provides a powerful foundation for conservation genetics research and plant breeding programs. To our knowledge, this is the first report on the plastid genome of
Passiflora tripartita var.
mollissima from Peru.
