Abstract
The ectopic expression of FOREVER YOUNG FLOWER (FYF), a MADS box gene in Arabidopsis, caused significant delay of senescence and a deficiency of abscission in flowers of transgenic Arabidopsis. It was proposed that the function of the FYF gene was related to the regulation of senescence and abscission. This hypothesis was further supported by one line of evidence reported in this study. The evidence is the similar delay of flower senescence and abscission observed in transgenic Arabidopsis ectopically expressing OnFYF, an FYF homolog from the Oncidium orchid, a monocot. This data suggested that the function of FYF homologs in regulating flower senescence and abscission was highly conserved in both dicot and monocot plants.
摘要
拟南芥 FYF（MADS box 基因）的异位表达导致转基因拟南芥花衰老和脱落的严重延迟。有人提出 FYF 基因的功能与衰老和脱落的调节有关。本研究中的一条证据进一步支持了这一假设。该证据是在异位表达 OnFYF 的转基因拟南芥中观察到的花衰老和脱落的类似延迟，OnFYF 是来自兰花的 FYF 同源物，兰花是单子叶植物。这些数据表明 FYF 同源物在调节花衰老和脱落方面的功能在双子叶植物和单子叶植物中高度保守。
