Overview

Randomized trial showcases genome traits linked to domestication in Silphium hybrids, implying potential for crop development.

Key Points

  • The aim is to improve the understanding of Silphium genomes for enhancing agricultural diversity and resilience.
  • Phased genome assemblies for Silphium integrifolium and S. perfoliatum were created.
  • Utilized trio-binning to facilitate genome assembly from an interspecific hybrid.
  • Employed a low coverage and target sequencing strategy to analyze phylogeny and natural populations.
  • Identified 81 loci related to environmental adaptation and domestication traits.
  • Significant variance in floral architecture linked to variants in MATE transporter and α/β hydrolase.
  • Genome assembly advances could broaden crop domestication candidates.
