Abstract
在更高的植物的 flowering 时间的控制是最重要的生理的进程之一并且为他们的繁殖成功是批评的。调查控制 flowering 时间的机制，我们与迟了花的显型为 Arabidopsis 屏蔽了异种。在 Landsberg erecta (Ler ) 的一变异的、指明的推迟的 flowering (dfr ) 生态型，与推迟的 flowering 时间被识别。基因分析表明 dfr 是单个基因后退的原子异种和变化被印射到紧在染色体 1 上连接到飞碟的一个地点。到我们的知识，调整 flowering 时间的基因还都没在这个区域被报导。dfr 异种植物在检验的不同生长条件下面显示出一推迟的 flowering 时间，包括长天、短天的光周期和 gibberellic 酸 GA3 处理，建议 DFR 是涉及自治 flowering 提升小径的基因。Arabidopsis 基因 FLOWERING 地点 C (FLC ) 在镇压起一个中央作用 flowering 和它的抄本在野类型的 Ler 是无法发现的。然而， FLC 表示是在 dfr 异种的 upregulated，建议 DFR 是 FLC 的一个否定管理者。另外， dfr 异种植物显示了 silique 的改变的阀门形状和毛状体的数字，每毛状体的分支是减少的两个，显示 DRF 基因也为正常植物开发被要求。而且，两倍异种种的 dfr leafy-5 (lfy-5 ) 比 dfr 或 lfy-5 单身者显示出一以后的 flowering 时间异种， synergistically 显示那 DFR 和 LFY 幕在 Arabidopsis 支持 flowering。
