Little is known about the mechanisms by which mRNAs are transported over long distances in the phloem between the rootstock and the scion in grafted woody plants. We identified an mRNA in the pear variety ‘Du Li’ (Pyrus betulaefolia) that was shown to be transportable in the phloem. It contains a WU...
