• Information
  • Symbol: OsSh1
  • MSU: LOC_Os03g44710
  • RAPdb: Os03g0650000
• Publication
  • Parallel domestication of the Shattering1 genes in cereals, 2012, Nat Genet.
  • Direct identification of a mutation in OsSh1 causing non-shattering in a rice Oryza sativa L. mutant cultivar using whole-genome resequencing, 2020, Sci Rep.
• Genbank accession number
  • AK070258
• Key message
  • The function of the rice ortholog (OsSh1) was subsequently validated with a shattering-resistant mutant, and two maize orthologs (ZmSh1-1 and ZmSh1-5
  • Whole-genome mutation analysis of ‘Minamiyutaka’ newly identified a 13-bp deletion causing defective splicing in exon 3 of the OsSh1 gene which has previously been referred to as a candidate for controlling seed shattering
  • Nucleotide diversity analysis of OsSh1 in wild rice accessions and cultivars revealed that OsSh1 has been under strong selection during rice domestication, and a missense mutation might have contributed to the reduction of seed shattering from the wild progenitors to cultivated rice
• Connection
  • OsSh1, qSH1~RIL1, Direct identification of a mutation in OsSh1 causing non-shattering in a rice Oryza sativa L. mutant cultivar using whole-genome resequencing, Furthermore, gene expression analysis suggests that OsSh1 may function downstream of qSH1, a known key gene involved in abscission zone differentiation
