Gene Details:

• Gene ID: Solyc05g010000
• Gene Symbol: SlIDA
• Gene Name: IDA homolog
• Genome: Tomato Genome version SL4.0
• Species: Solanum lycopersicum

Functional Descriptions:

• SlIDA expression during anther development and pollen tube elongation.
• Tomato SlIDA has a critical role in tomato fertilization by modifying reactive oxygen species homeostasis.
• We generated tomato knockout lines (CR-SlIDA) of an IDA homolog (SlIDA), which is expressed in the tapetum, septum and pollen tube, and observed a severe defect in male gametes.
• Liquid chromatography-tandem mass spectrometry identified mature SlIDA as a 14-mer EPIP peptide, which was shown to be secreted, and a complementation experiment showed that application of a synthetic 14-mer EPIP peptide rescued the CR-SlIDA defect and enhanced the ROS signal.
• Collectively, our results revealed that SlIDA plays an essential role in pollen development and pollen tube elongation by modulating ROS homeostasis.
