Gene losses in the common vampire bat illuminate molecular adaptations to blood feeding
Open accessPublished version of a preprint
Abstract
Vampire bats are the only mammals that feed exclusively on blood. To uncover genomic changes associated with this dietary adaptation, we generated a haplotype-resolved genome of the common vampire bat and screened 27 bat species for genes that were specifically lost in the vampire bat lineage. We found previously unknown gene losses that relate to reduced insulin secretion ( FFAR1 and SLC30A8 ), limited glycogen stores ( PPP1R3E ), and a unique gastric physiology ( CTSE ). Other gene losses likely reflect the biased nutrient composition ( ERN2 and CTRL ) and distinct pathogen diversity of blood ( RNASE7 ) and predict the complete lack of cone-based vision in these strictly nocturnal bats ( PDE6H and PDE6C ). Notably, REP15 loss likely helped vampire bats adapt to high dietary iron levels by enhancing iron excretion, and the loss of CYP39A1 could have contributed to their exceptional cognitive abilities. These findings enhance our understanding of vampire bat biology and the genomic underpinnings of adaptations to blood feeding.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
