The present invention provides the chromosomal location and structure of a gene involved in the determination of row type and panicle morphology of barley. The present inventors have found that the row type and panicle morphology of barley can be altered by introducing the Vrs 1 gene provided by the present invention into barley and regulating its expression. Furthermore, the present inventors found the possibility of enhancing the resistance of barley to Fusarium head blight. Thus, barley having phenotypes suitable for the intended purpose can be created by efficiently altering the row type and panicle morphology of barley.
本发明提供了参与决定大麦行型和圆锥花序形态的
基因的染色体位置和结构。本发明人发现,通过将本发明提供的 Vrs 1
基因导入大麦并调节其表达,可以改变大麦的行型和圆锥花序形态。此外,本发明者还发现有可能增强大麦对镰刀菌头疫病的抗性。因此,通过有效改变大麦的行型和圆锥花序形态,可以培育出具有适合预期目的表型的大麦。
