Gene Details:

• MSU gene ID: LOC_Os04g56170
• RAPdb gene ID: Os04g0656500
• Gene Symbol: OsLG1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Association analysis indicates that a single-nucleotide polymorphism-6 in the OsLG1 regulatory region led to a compact panicle architecture in cultivars during rice domestication.
• Transgenic plants harboring the OsLG1 promoter:GUS (beta-glucuronidase) reporter gene construct display preferential expression in developing laminar joint regions and meristemic regions.
• Here we show that the spread panicle architecture of wild rice is controlled by a dominant gene, OsLG1, a previously reported SBP-domain transcription factor that controls rice ligule development.
• These results indicate that OsLG1 is a transcriptional factor that plays an important role in building the laminar joint between leaf blade and leaf sheath boundary, thereby controlling ligule and auricle development.
• OsLG1 regulates a closed panicle trait in domesticated rice.
