• Information
  • Symbol: OSH6
  • MSU: LOC_Os01g19694
  • RAPdb: Os01g0302500
• Publication
  • Overexpression of rice OSH genes induces ectopic shoots on leaf sheaths of transgenic rice plants, 2000, Dev Biol.
  • KNOX homeobox genes are sufficient in maintaining cultured cells in an undifferentiated state in rice, 2001, Genesis.
  • Regional expression of the rice KN1-type homeobox gene family during embryo, shoot, and flower development, 1999, Plant Cell.
  • A Ds-insertion mutant of OSH6 Oryza sativa Homeobox 6 exhibits outgrowth of vestigial leaf-like structures, bracts, in rice, 2007, Planta.
  • Transcriptome comparison between pluripotent and non-pluripotent calli derived from mature rice seeds, 2020, Sci Rep.
• Genbank accession number
  • AK241312
• Key message
  • These data suggest that OSH6-Ds interferes with a developmental mechanism involved in bract differentiation, especially at the basal nodes of panicles
  • A Ds-insertion mutant of OSH6 (Oryza sativa Homeobox 6) exhibits outgrowth of vestigial leaf-like structures, bracts, in rice
  • The truncated mRNA was expressed ectopically in leaf tissues and encoded the N-terminal region of OSH6, which includes the KNOX1 and partial KNOX2 subdomains
  • These phenotypes distinguished it from the OSH6 transgene whose ectopic expression led to a blade to sheath transformation phenotype at the midrib region of leaves, similar to that seen in dominant Lg3 mutants
