最近，大量的mRNA被证明能够通过筛元件在植物器官之间旅行，作为一种假定的长距离信号分子。然而，转录本被选择用于运输的机制基础尚未确定。在这里，我们表明，在拟南芥中的实验mRNA的流动性数据可以解释的转录丰度和半衰期。这表明大多数鉴定的移动的转录物可以通过mRNA从伴胞到筛元件的非序列特异性移动来解释。
Recently, a large population of mRNA was shown to be able to travel between plant organs via sieve elements as a putative long-distance signaling molecule. However, a mechanistic basis by which transcripts are selected for transport has not yet been identified. Here, we show that experimental mRNA mobility data in Arabidopsis can be explained by transcript abundance and half-life. This suggests that the majority of identified mobile transcripts can be accounted for by non-sequence-specific movement of mRNA from companion cells into sieve elements.
