Gene Details:

• Gene ID: Solyc03g120960
• Gene Symbol: Sl-STIG1
• Gene Name: STIGMA-SPECIFIC PROTEIN1
• Genome: Tomato Genome version SL4.0
• Species: Solanum lycopersicum

Functional Descriptions:

• Tomato Pistil Factor STIG1 Promotes in Vivo Pollen Tube Growth by Binding to Phosphatidylinositol 3-Phosphate and the Extracellular Domain of the Pollen Receptor Kinase LePRK2.
• Silencing of STIG1 reduced both the in vivo pollen tube elongation rate and seed production.
• Exogenous STIG1 elevated the overall redox potential of pollen tubes in both PI(3)P-dependent and LePRK2-dependent manners.
• Our results demonstrate that STIG1 conveys growth-promoting signals acting through the pollen receptor kinase LePRK2, a process that relies on the external phosphoinositide PI(3)P.
