Avenanthramide concentrations in developing oat genotypes as influenced by crown rust
, 2004 Oat (Avena sativa L.) avenanthramides are unique antioxidant compounds found constitutively in mature grain and inducible in seedling leaves by crown rust (Puccinia coronata Corda. var. avenae W.P.

Genomic insights from the first chromosome-scale assemblies of oat (Avena spp.) diploid species
BMC Biology, 2019 Background Cultivated hexaploid oat (Common oat; Avena sativa) has held a significant place within the global crop community for centuries; although its cultivation has decreased over the past century, its nutritional benefits have garnered increased ...

Induction of crown rust resistance in oat by high temperature stress.
Japanese Journal of Phytopathology, 1987 エンバク冠さび菌の親和性レースを接種した3品種のエンバク子苗を接種2-4日後に35C, 8時間で処理すると,夏胞子堆形成が著しく阻害された。高温処理の部位は接種部を含んでいることが必須であった。同処理条件は菌体に直接影響して致死効果を示すものではなく,宿主に作用して抵抗性を誘導することが茎の切断処理による実験で確認された。接種5日後には高温処理の影響は現われなかった。高温処理初生葉において,夏胞子堆形成が阻害された場合にはリポキシゲナーゼアイソザイムが特異的に出現することから,本酵素が抵抗性発現に関与すると考えた。
