| The phloem is part of the plant long-distance transport system that is important for the distribution of assimilates and information between different organs. Systemic communication is essential in plant nutrition to coordinate nutrient availability with the resources required for defense responses, growth and reproduction. During recent years an increasing number of small RNAs, including the important class of regulatory micro (mi) RNAs, have been identified in phloem samples from different plant species, and their involvement in systemic information transfer has been suggested. Grafting experiments provided further evidence that specific nutrient deficiency-induced miRNAs are indeed phloem-mobile in vivo and can influence the expression of their target transcripts at their destination. The results indicate that miRNA translocation via the phloem might be important for a temporal coordination of stress responses between plant organs. Future experiments will be required to establish the exact physiological functions of systemic miRNAs and their possible interactions with other signaling networks involved in the coordination of plant nutrition. | |
