New reference genome assembly for the declining American Bumble Bee, Bombus pensylvanicus.

ABSTRACT: We present the first chromosome-level genome assembly for Bombus pensylvanicus, a historically widespread native pollinator species that was distributed across eastern North America but has subsequently undergone declines in range area and local relative abundance. This species has been of significant interest as a model for understanding both patterns and possible causes of bumble bee decline in the region, including the role of genetic variation. Here we present a chromosome-level reference genome assembled using Pacific Biosciences singe-molecule HiFi sequences and Hi-C data and annotated using evidence derived from RNA sequencing of multiple tissue types. The B. pensylvanicus genome has a total length of ∼352.6 Mb and was assembled into a total of 224 scaffolds, with 19 primary pseudom
