“…This movement of RNA to stolon tips is facilitated by a short-day photoperiod, mediated by sequence tags present in the untranslated regions of the StBEL5 transcript, and correlated with enhanced tuber production (Banerjee et al 2006). Based on these results, the mRNA of StBEL5 appears to act as a mobile signal that is delivered to the stolon tip to induce tuber formation.…”

“…transcripts are present in phloem cells and move across a graft union to localize in stolon tips, the site of tuber induction (Banerjee et al 2006). This movement of RNA to stolon tips is facilitated by a short-day photoperiod, mediated by sequence tags present in the untranslated regions of the StBEL5 transcript, and correlated with enhanced tuber production (Banerjee et al 2006).…”

“…Subsequently cytokinin levels are enhanced and the result of this pathway is enhanced tuber formation (Banerjee et al 2006). It is not known if BEL5 is functional in NTB species, but studying RNA accumulation patterns in the leaf, stem, and roots will help answer this question.…”

“…Of these, CmGAIP, CmNACP, and CmPP16 are from Cucurbita maxima (Haywood et al 2005;Ruiz-Medrano et al 1999;Xoconostle-Cazares et al 1999), DELLA-GAI is from Arabidopsis (Haywood et al 2005), PFP-LeT6 is from tomato (Kim et al 2001), and StBEL5 is from potato (Banerjee et al 2006). Using the Cucurbita species, scions of cucumber grafted onto pumpkin stocks provided direct evidence that specific pumpkin mRNAs were translocated through the heterograft via the phloem into the shoot apex (Ruiz-Medrano et al 1999;Xoconostle-Cazares et al 1999).…”

“…The discovery of the RNAbinding protein, CmPP16, provided additional support for the long-distance transport of RNA in pumpkin (Xoconostle-Cazares et al 1999). Of this group of six RNAs, however, information on the dynamics of movement is available only for StBEL5 RNA (Banerjee et al 2006). …”

Phloem sap contains a wide range of macromolecules, including ribonucleic acids (RNAs) and proteins. Recent advances in genomic and proteomic technologies have enabled the identification of thousands of these macromolecules. However, technical limitations are still the main obstacle to the complete characterization of macromolecule profiles in the sieve tube. Grafting experiments have established that numerous macromolecules are capable of moving long distances between tissues, providing the foundation for the hypothesis of an interorgan information superhighway in higher plants involving the phloem. This chapter presents the current knowledge on proteins and messenger RNA (mRNA) molecules present in the sieve tube. The challenge now is to characterize the biological role of trafficking macromolecules, such as their involvement in the signal‐transduction pathway(s) elicited by environmental cues and in orchestrating developmental processes at the whole‐plant level. Key concepts Phloem sap contains macromolecules such as proteins and RNAs. Protein profiles in the sieve tube are tissue specific. Phloem proteins act as long‐distance signalling molecules. Plant viruses move long distance via the phloem. Endogenous RNA molecules are capable of trafficking long distance via the phloem. mRNA molecules may act as long‐distance signalling molecules.

The vascular tissue has been essential for the evolutionary radiation of land plants, and has allowed them to colonise a wide range of habitats. The phloem is involved in the distribution of fixed carbon throughout the whole plant. The concept of this tissue as a central distributor of signals that regulate plant development and responses to environmental cues has emerged recently. Indeed, several phenomena, such as post‐transcriptional gene silencing, flowering and tuber induction, as well as systemic acquired resistance to pathogens rely on signals, originating in source leaves, and transported via the phloem to systemic tissues. Considering that the phloem translocation stream contains a large array of macromolecules. Given that the functional phloem consists of interconnected enucleate cells, the sieve elements (SEs), the majority of proteins and ribonucleic acids (RNAs) found in phloem sap exudates must originate from the adjoining companion cell (CC). While several proteins play a role in the maintenance of the SEs, it is possible that several species of proteins and RNAs function in long‐distance signalling. In this article the current state of the art of this subject is described, as well as perspectives and possible applications for crop improvement. Key Concepts The vascular tissue consists of xylem and phloem. The xylem is composed of vessels that are dead cells upon maturity that transport mineral nutrients from roots to shoots. The phloem is composed of vessels formed from enucleated living cells involved in the transport of fixed carbon from photosynthetic to heterotrophic organs. The phloem is involved in the delivery of signals that control development as well as responses to external stimuli, such as defence response, post‐transcriptional gene silencing and response to phosphate starvation. Viruses and viroids are transported through the phloem during systemic infection. These probably take advantage of a system enabling long‐distance transport of endogenous proteins and RNAs. The phloem translocation stream contains a wide variety of proteins and RNAs, some of which appear to have a signalling function. RNA and protein exchange can occur between plant pathogenic fungi and parasitic plants and their hosts. Knowledge of this RNA and protein phloem transport system can have applications for crop improvement.
