Whole genome sequence and annotation of Penstemon davidsonii

Penstemon is the most speciose flowering plant genus endemic to North
America. Penstemon species' diverse morphology and adaptation to
various environments have made them a valuable model system for studying
evolution, but the absence of publicly available reference genomes limits
possible research directions. Here we report the first reference genome
assembly and annotation for Penstemon davidsonii. Using PacBio long-read
sequencing and Hi-C scaffolding technology, we constructed a de novo
reference genome of 437,568,744 bases, with a contig N50 of 40 Mb and L50
of 5. The annotation includes 18,199 gene models, and both the genome and
transcriptome assembly contain over 95% complete eudicot BUSCOs. This
genome assembly will serve as a valuable reference for studying the
evolutionary history and genetic diversity of the Penstemon genus.
