Global Team Maps Oat Diversity With Pangenome, Pantranscriptome and 9,000-Sample Analysis

The new genomic maps equip breeders to target specific traits for nutrition, adaptation, productivity.

Overview

  • A Nature study assembles a pangenome from 33 wild and domesticated oat lines and a pantranscriptome profiling six tissues in 23 lines.
  • The work details widespread inversions and translocations in oat’s hexaploid genome, clarifying a key reason breeding has lagged other cereals.
  • A companion Nature Communications analysis of roughly 9,000 global samples links several of the same chromosomal rearrangements to local environmental adaptation.
  • Researchers document gene loss in one subgenome with compensation by other copies, including impacts on regulators of flowering time.
  • The publicly available reference panels and expression atlas enable more precise selection for beta-glucan content, plant height, flowering time, and drought tolerance.
