Abstract

Structural variations (SVs) play crucial roles in the evolutionary adaptation of domesticated animals to natural and human-controlled environments, but SVs have not been explored in Tibetan cattle, which recently migrated and rapidly adapted to the high altitudes of the Qinghai-Tibetan Plateau (QTP). In this study, a de novo chromosome-level genome assembly for Tibetan cattle is constructed. It is found that using a lineage-specific reference genome significantly increased variant detection accuracy and completeness. Analysis of long-read sequencing data from 36 high-altitude QTP and 48 low-altitude cattle identified 222 528 SVs and 259 SV hotspot regions. Positively selected SVs in high-altitude cattle are related to energy metabolism erythropoiesis and angiogenesis, and peroxisomal metabolism. A 102-bp intronic deletion in GNPAT likely upregulated its expression. It is distinguished 7293 SVs that may be introgressed from yak, including variants upstream of the hypoxia-inducing gene EGLN1. Finally, a ≈2-Mb heterozygous inversion and two translocations on chromosome 6 are likely associated with the cattle gray coat via regulatory effects on the KIT gene. The results confirm the importance of SVs in evolutionary adaptation and the contribution yak-introgressed SVs to the rapid acclimatization of QTP cattle.

  • 7293 SVs in Tibetan cattle originated from yak introgression, including an upstream regulatory variant of EGLN1 and intronic deletions in PPP1R14C and NFE2L2.

    “A structural variation analysis further revealed that 7293 SVs in Tibetan cattle originated from yak introgression. These variants included an upstream regulatory variant of EGLN1 and intronic deletions in PPP1R14C and NFE2L2, which are associated with angiogenesis and glucose transporter 1 upregulation, respectively [89].”

    From The Genomic Landscape of Cattle: Domestication, Dispersal, and Adaptive Evolution (2026) · cites this paper as [89]

    The Results (‘Yak Introgression’; page not supplied) identify 7,293 SVs as possibly derived from yak, with 5,642 subsequently classified as probable introgressions. The same section reports SVs upstream of EGLN1 and intronic deletions in PPP1R14C and NFE2L2. The claim overstates the certainty of yak origin for all 7,293 and calls the EGLN1 variant regulatory, whereas the passage establishes its location upstream of the gene, not a regulatory effect.

  • A 2 Mb heterozygous inversion and two translocations harboring KIT were associated with the gray coat phenotype in Tibetan cattle, and the inversion haplotype originated from South Asian indicine cattle.

    “A 2 Mb heterozygous inversion and two translocations harboring genes including KIT were associated with the gray coat phenotype in Tibetan cattle, and the inversion haplotype segment originated from South Asian indicine cattle [89].”

    From The Genomic Landscape of Cattle: Domestication, Dispersal, and Adaptive Evolution (2026) · cites this paper as [89]

    The Results section (“A 2-Mb Heterozygous Inversion Related to the Gray Coat Phenotype”) identifies a 2-Mb heterozygous inversion and two translocations associated with gray coat color; the region includes KIT. Its haplotype analysis suggests the inversion segment likely originated from South Asian indicine cattle, but the citing sentence states that origin as certain. (LLM, conf=0.87)

  • Structural variation analyses identified genes involved in erythropoiesis and angiogenesis and energy metabolism in high-altitude cattle.

    “Structural variation analyses further identified genes involved in erythropoiesis and angiogenesis (SSH2, VGLL4, PLCB1, HPSE2, HPSE) and energy metabolism (SORD, NDUFB6, SARDH, ADIPOQ) [89].”
  • Precise characterization of SVs has linked a 108 bp insertion in SPN to M. tuberculosis resistance and associated specific upstream variants of EGLN1 to high-altitude adaptation.

    “Furthermore, precise characterization of SVs has linked a 108 bp insertion in SPN to M. tuberculosis resistance and associated specific upstream variants of EGLN1 to high-altitude adaptation [89,101].”

    From The Genomic Landscape of Cattle: Domestication, Dispersal, and Adaptive Evolution (2026) · cites this paper as [89]

    The Introduction mentions EGLN1 only as a candidate identified by previous SNP studies, not as a gene with upstream SVs characterized in this paper. The Results identify other SVs associated with high-altitude adaptation, but searches for SPN, a 108-bp insertion, tuberculosis resistance, and upstream EGLN1 variants found no passage addressing either specific claim. Page numbers were not available in our copy. (LLM, conf=0.76)

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.
