>title: "Full-length mobile RNA as a developmental signal"
>Abstract
>
>BEL1-like transcription factors are ubiquitous in plants and interact
>with KNOTTED1-types to regulate numerous developmental processes. In
>potato, the BEL1-like transcription factor, StBEL5, and its Knox
>protein partner regulate tuber formation by targeting genes that
>control growth. RNA detection methods and heterografting experiments
>demonstrated that StBEL5 transcripts are present in phloem cells and
>move across a graft union to localize in stolon tips, the site of
>tuber induction. This movement of RNA originates in leaf veins and
>petioles and is induced by a short-day photoperiod, regulated by the
>untranslated regions, and correlated with enhanced tuber production.
>Addition of the StBEL5 untranslated regions to another BEL1-like mRNA
>resulted in its preferential transport to stolon tips and enhanced
>tuber production. The detection of several other full-length mRNAs
>from the KNOTTED1- and BEL1-like families in phloem sap indicates
>that what is known about mRNAs as long-distance signals is just the
>tip of the iceberg.
