Gene Details:

• MSU gene ID: LOC_Os03g63010
• RAPdb gene ID: Os03g0847500
• Gene Symbol: PTOX1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Using Ecotype Targeting Induced Local Lesions IN Genomes (EcoTILLING) and TILLING as forward genetic tools, we identified the causative mutation of an EMS mutant characterized by excessive tillering, semi-dwarfism and leaf variegation that corresponded to the PTOX1 gene.
• The tillering and semi-dwarf phenotypes of the PTOX1 mutant are similar to phenotypes of known strigolactone (SL)-related rice mutants, and both phenotypic traits could be rescued by application of the synthetic SL GR24.
• The PTOX1 mutant accumulated phytoene in white leaf sectors with a corresponding deficiency in beta-carotene, consistent with the expected function of PTOX1 in promoting phytoene desaturase activity.
