Cultivated peanut AhGPAT9A gene and application thereof in improving oil content of seeds

The invention discloses a cultivated peanut AhGPAT9A gene and an application thereof in improving the oil content of seeds. According to the invention, an AhGPAT9A gene derived from an A chromosome group of cultivated peanuts is obtained by cloning, the function of the AhGPAT9A gene is investigated by constructing a transgenic peanut strain, and it is found that the AhGPAT9A gene has a significantinfluence on the oil content of peanut seeds. Therefore, the cultivated peanut AhGPAT9A gene has important theoretical guidance significance and practical application value for analyzing a peanut high-oil molecular mechanism, improving the high-oil molecular breeding technology level and cultivating a new high-oil variety. 本发明公开了一种栽培花生AhGPAT9A基因及其在改良种子含油量中的应用。本发明克隆得到了来源于栽培花生A染色体组的AhGPAT9A基因；并通过构建转基因花生株系，对AhGPAT9A基因的功能进行了考察，发现AhGPAT9A基因对花生种子的含油量有显著影响。因此，本发明对解析花生高油分子机制，提升高油分子育种技术水平，培育高油新品种都具有重要的理论指导意义和实践应用价值。
