Gene Details:

• MSU gene ID: LOC_Os01g62920
• RAPdb gene ID: Os01g0848400
• Gene Symbol: qSH1 RIL1
• Genome: MSU7 ,  IRGSP-1.0
• Species: Oryza sativa

Functional Descriptions:

• Here, we studied nucleotide variation at the shattering loci, sh4 and qSH1, for cultivated rice, Oryza sativa ssp.
• We revealed that the qSH1 gene, a major quantitative trait locus of seed shattering in rice, encodes a BEL1-type homeobox gene and demonstrated that a single-nucleotide polymorphism (SNP) in the 5’ regulatory region of the qSH1 gene caused loss of seed shattering owing to the absence of abscission layer formation.
• Genomewide association analysis for awn length linked to the seed shattering gene qSH1 in rice.
• Special interest was the detection of the most significant association SNP, sf0136352825, which was less than 95 kb from the seed shattering gene qSH1.
• In addition, both RI and RIL1 seem to be involved in meristem maintenance, because the ri RIL1 double mutant failed to establish or maintain the shoot apical meristem during embryogenesis.
