贵州省农科院 贵州茅台 酒用高粱 红缨子 T2T组装

2024/7/5
高粱是世界重要的粮食作物，在中国主要用于白酒酿造。红缨子作为酱香型白酒生产的主要原料，是目前中国累计推广面积最大的高粱品种。现有的多个高粱参考基因组均来自于饲料和能源用品种，与专门用于白酒生产的中国品种存在显著的遗传差异。而且由于采用测序技术的固有局限性，高度重复的基因组区域（如端粒和着丝粒）难以精确组装和注释，导致现有高粱参考基因组中仍然存在大量的间隙（gap）区域。

芝麻（Sesamum indicum L.）是含油量最高的一年生草本油料作物。芝麻枯萎病由Fusarium oxysporum f. sp. sesami（Fos）侵染引起，是芝麻两大真菌病害之一。开展抗枯萎病关键基因挖掘对解析芝麻等农作物抗病遗传机制、实现品种抗性改良具有重要意义。目前，尚未从芝麻栽培种中发掘出与枯萎病抗性相关的优异基因（位点）。
