- Key message
- 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

- 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
- qSH1~RIL1, RHS1, A Novel RHS1 Locus in Rice Attributes Seed-Pod Shattering by the Regulation of Endogenous S-Nitrosothiols., Interestingly, the basal expression levels of QSH1 and SHAT1 genes (transcription factors that regulate seed-pod shattering in rice) were significantly lower in these plants than in wild-type plants; however, nitrosative stress negatively regulated the expression of QSH1 and SHAT1 in both WT and rhs1 plants, but positively regulated QSH4 expression in rhs1 plants alone
