Comparative Genomics Reveals Recent Adaptive Evolution in Himalayan Giant Honeybee Apis laboriosa.

ABSTRACT: The Himalayan giant honeybee, Apis laboriosa, is the largest individual honeybee with major ecological and economic importance in high-latitude environments. However, our understanding of its environmental adaptations is circumscribed by the paucity of genomic data for this species. Here, we provide a draft genome of wild A. laboriosa, along with a comparison to its closely related species, Apis dorsata. The draft genome of A. laboriosa based on the de novo assembly is 226.1 Mbp in length with a scaffold N50 size of 3.34 Mbp, a GC content of 32.2%, a repeat content of 6.86%, and a gene family number of 8,404. Comparative genomics analysis revealed that the genes in A. laboriosa genome have undergone stronger positive selection (2.5 times more genes) and more recent duplication/loss events
