• Information
  • Symbol: TAW1
  • MSU: LOC_Os10g33780
  • RAPdb: Os10g0478000
• Publication
  • TAWAWA1, a regulator of rice inflorescence architecture, functions through the suppression of meristem phase transition, 2013, Proc Natl Acad Sci U S A.
• Genbank accession number
  • AK243306
• Key message
  • In contrast, reductions in TAWAWA1 (TAW1) activity cause precocious IM abortion and spikelet formation, resulting in the generation of small inflorescences
  • We thus propose that TAW1 is a unique regulator of meristem activity in rice and regulates inflorescence development through the promotion of IM activity and suppression of the phase change to SM identity
  • TAW1 expression disappears from incipient spikelet meristems (SMs)
  • TAW1 encodes a nuclear protein of unknown function and shows high levels of expression in the shoot apical meristem, the IM, and the BMs
  • We also demonstrate that members of the SHORT VEGETATIVE PHASE subfamily of MADS-box genes function downstream of TAW1
• Connection
  • OsG1L1, TAW1, The ALOG family members OsG1L1 and OsG1L2 regulate inflorescence branching in rice., Recently, by combining precise laser microdissection of inflorescence meristems with RNA-seq, we observed that two ALOG genes, OsG1-like 1 (OsG1L1) and OsG1L2, have expression profiles similar to that of TAW1
  • OsG1L1, TAW1, The ALOG family members OsG1L1 and OsG1L2 regulate inflorescence branching in rice., Here, we report that osg1l1 and osg1l2 loss-of-function CRISPR mutants have similar phenotypes to the phenotype of the previously published taw1 mutant, suggesting that these genes might act on related pathways during inflorescence development
  • OsG1L2, TAW1, The ALOG family members OsG1L1 and OsG1L2 regulate inflorescence branching in rice., Recently, by combining precise laser microdissection of inflorescence meristems with RNA-seq, we observed that two ALOG genes, OsG1-like 1 (OsG1L1) and OsG1L2, have expression profiles similar to that of TAW1
