Many genes regulating soybean flowering time are identified. To analyze the relationship among these soybean flowering genes, we developed six near-isogenic lines harboring contrast genotype for Japanese soybean cultivar "Enrei". The amounts of E1 transcript up-regulated under long-day condition were highly correlated with the transcripts level of soybean florigen genes and their flowering phenotypes. These results indicated that the regulation of E1 gene expressions was probably controlled independently by several soybean flowering genes.

已鉴定出许多控制大豆开花时间的基因。为了分析这些大豆开花基因之间的关系，我们培育了6个日本大豆品种“恩瑞”的近等基因系。在长日照条件下，大豆成花基因的转录水平与其开花表型呈高度正相关。这些结果表明，E1基因表达的调控可能是由多个大豆开花基因独立控制的。
