Global Team Publishes Oat Pangenome and Gene Atlas, Mapping Variants Tied to Adaptation

The new genomic resources give breeders a roadmap to target nutrition, yield, climate resilience.

Overview

  • The pangenome charts genetic diversity across 33 wild and cultivated oat lines, capturing both shared and line‑specific genes.
  • The pantranscriptome profiles gene activity across six tissues and developmental stages in 23 lines, creating a gene expression atlas.
  • Large chromosomal inversions and translocations identified in the genomes were linked to local environmental adaptation in a companion analysis of roughly 9,000 samples.
  • Researchers report gene loss in one of the three oat subgenomes with compensatory copies maintaining function, including effects on flowering-time control.
  • The international PanOat consortium says the reference datasets and chromosomal maps position breeders to more precisely select traits such as beta‑glucan content, plant height, flowering time, and drought tolerance.
