| Outline of Final Research Achievements |
The results of split-root culture indicated that, when some roots recognize Phosphate or Fe-starvation, a long-distance signaling is initiated in the portion of the root directly experiencing Phosphate or Fe-starvation. Then, this information transmit to another roots through “root-to-shoot-to-root” pathway. A series of genes that involved in Phosphate or Fe uptake and metabolism are concomitantly induced on the other side of the roots to compensate for the local Phosphate or Fe-deficiency.
We also identified several mobile signal candidates for long-distance signaling in response to Phosphate or Fe-starvation through the transcriptome analysis and proteome analysis using the xylem sap of Tomato.
