调控大白菜春化性状的因子及方法
摘要：
本发明涉及调控大白菜春化性状的因子及方法。公开了一种大白菜开花调控素2基因(BRF2)、其正向转录本或表达产物的用途，用于调控十字花科植物的春化性状。还公开了一种调控十字花科植物的春化性状的方法，包括将BRF2基因或BRF2正向转录本过表达转入十字花科植物中。还公开了制备春化延迟的转基因植物的方法。本发明揭示了十字花科植物春化性状特异性及其进化的分子机理；在实践上，可以根据本发明提供的调控因子的结构及其功能设计春化性状调控的分子靶点，可以将所述调控因子进行修饰导入十字花科植物以培育新型农艺性状品种。
摘要（英）：

The invention relates to a factor and a method for regulating vernalization trait of Chinese cabbage. The invention discloses application of Chinese cabbage blooming regulation factor 2 (BRF2) genes, positive transcripts or expression products thereof in regulation of vernalization traits of crucifers. The invention also discloses a method for regulating the vernalization traits of the crucifers, which comprises that the BRF2 genes or the BRF2 positive transcripts are transferred into the crucifers in an over expression mode. The invention also discloses a method for preparing a vernalization delayed transgenic plant. The invention discloses a molecular mechanism of vernalization trait specificity and evolution of the crucifers. In practice, according to the structure of the regulation factors and the molecular target of functional designed vernalization trait regulation, the regulation factors can be modified and guided into the crucifers to culture novel agronomic trait varieties.
