已知FLOWERLOCUS T(FT)蛋白是植物中移动的开花诱导“成花素”信号的一部分,但它可能不是单独起作用的。本文综述的数据,FT mRNA也可以系统地移动整个植物和进入茎顶端分生组织(SAM)独立的FT蛋白。在诱导条件下,当病毒表达的FT mRNA的水平增加与内源性产生的FT蛋白一起存在时,即使额外的FT mRNA是不可翻译的,因此不会增加FT蛋白的总体水平,也会促进开花。FT mRNA的特定序列或“邮政编码”是系统运动所需的,并且该序列结合植物提取物中的特定蛋白质。这增加了FT mRNA可能作为RNA-蛋白质复合物在植物中系统移动并进入SAM的可能性,FT蛋白是否也是这种移动的复合物的组分仍有待确定。
FLOWERING LOCUS T (FT) protein is known to be part of the mobile flowering inducing “florigen” signal in plants, but it may not be acting alone. This article reviews the data that FT mRNA can also move systemically throughout the plant and into the shoot apical meristem (SAM) independently of the FT protein. There is a promotion of flowering when increased levels of virally expressed FT mRNA are present together with endogenously produced FT protein in inducing conditions, even if the additional FT mRNA is non-translatable and thus not increasing the overall levels of FT protein. A specific sequence, or “zip code” of the FT mRNA is required for systemic movement and this sequence binds a specific protein(s) in plant extracts. This raises the possibility the FT mRNA may be moving systemically through the plant and into the SAM as an RNA–protein complex, whether FT protein is also a component of this mobile complex remains to be determined.
