Abstract

Objectives: Petrea volubilis, a member of the Order Lamiales and the Verbenaceae family, is an important horticultural species that has been used in traditional folk medicine. To provide a genome sequence for comparative studies within the Order Lamiales that includes important families such as Lamiaceae (mints), we generated a long-read, chromosome-scale genome assembly of this species.

Data description: Using a total of 45.5 Gb of Pacific Biosciences long read sequence, we generated a 480.2 Mb assembly of P. volubilis, of which, 93% is chromosome anchored. Representation of genic regions was robust with 96.6% of the Benchmarking of Universal Single Copy Orthologs present in the genome assembly. A total of 57.8% of the genome was annotated as a repetitive sequence. Using a gene annotation pipeline that included refinement of gene models using transcript evidence, 30,982 high confidence genes were annotated. Access to the P. volubilis genome will facilitate evolutionary studies in the Lamiales, a key order of Asterids that includes significant crop and medicinal plant species.

Keywords: Comparative genomics; Genome assembly; Lamiales; Petrea volubilis; Queen's wreath.
