In higher plants, the phloem acts not only as a conduit for photosynthates but also as a dynamic signalling highway for macromolecules such as RNAs. Messenger RNAs (mRNAs), small interfering RNAs and ...
Plants rely on an intricate network of transport pathways to distribute photoassimilates from sites of synthesis (sources) to sites of utilisation or storage (sinks). Sucrose, the principal transport ...
