The study presents the chromosome-level genome assembly of Avena longiglumis, a diploid oat species. The assembly is high-quality, with 99% completeness and 40,845 annotated protein-coding genes. It provides insights into genome evolution, expansion, and structural variations, offering valuable information for oat breeding and functional genomics. Additionally, mitochondrial genome and comparative studies have been conducted.
