The phloem is part of the plant long-distance transport system that is important for the distribution of assimilates between different organs. Moreover, its pathway is used to transfer important information that is required to coordinate nutrient availability with the resources required for defense responses, growth and reproduction. During the recent years an increasing number of small RNAs, including the important post-transcriptional gene expression regulators micro (mi) and short interfering (si) RNAs has been identified from phloem samples from different plant species, and their involvement in systemic communication has been suggested. More recently, grafting experiments also provided evidence that specific miRNAs, namely the nutrient deficiency-induced miR395 and miR399 and the tuberization-promoting miR172, are indeed mobile in vivo and can influence the expression of their target transcripts at their destination. The results indicate that miRNA translocation via the phloem is important for a temporal coordination of stress responses between plant organs. Moreover, the results on miR172 suggest that systemic regulation of development might, besides transcripts, proteins and phytohormones, also include a miRNA component. | |
