Gene Details:

• Gene ID: Solyc12g088670
• Gene Symbol: SlCyp1
• Gene Name: low-temperature-induced cysteine proteinase
• Genome: Tomato Genome version SL4.0
• Species: Solanum lycopersicum

Functional Descriptions:

• Here, we show that, in tomato, translocation of a phloem-mobile cyclophilin, SlCyp1, from a wild-type scion into a mutant rootstock results in restoration of vascular development and lateral root initiation.
• We show that long-distance trafficking of SlCyp1 is associated with regulation of the shoot-to-root ratio in response to changing light intensities, by modulating root growth.
• SlCyp1 is a key player in the signal transduction pathway that is required for maintaining a physiologically balanced shoot-to-root ratio under the prevailing environmental conditions.
• We conclude that long-distance trafficking of SlCyp1 acts as a rheostat to control the shoot-to-root ratio, by mediating root development to integrate photosynthesis and light intensity with requirements for access to water and mineral nutrients.
