Construction of sieve tubes has long been known, but only on the ultrastructure of recent reports allow you to fully understand how these creatures are well adapted to its function, ranging from reducing resistance to the flow of juice floemowego, by withstanding high pressures, up to safeguards against leakage of contents in the event of damage from the attack and pathogens. Floemowy juice contains not only sugars and ions, but also hormones, proteins and nucleic acids. These compounds are involved in signaling, as well as systemic immune reaction against viruses. For this reason, plant sieve tubes, although the cell strings are only within which transport takes place, can be considered as equivalent to the circulatory system, digestive, lymphatic, and even? transfer due to biophysical signals nervous animals.
