Other claims from this paper (7)
- Observation The KDS-1830C mutant had an opaque endosperm with a central cavity, unlike the normal translucent endosperm of wild-type Kitaake.
- Observation Scanning electron microscopy showed polygonal starch granules in Kitaake and irregularly shaped, rounded granules in KDS-1830C.
- Observation Grain width, thickness and weight differed significantly between KDS-1830C and wild type.
- Observation KDS-1830C had lower seed hardness.
- Observation QTL-seq identified a significant locus on chromosome 11 associated with the cavity phenotype.
- Observation A non-synonymous SNP in LOC_Os11g37560 was detected as the candidate causal mutation and is predicted to generate a premature stop codon.
- Mechanism Protein structure prediction suggests the nonsense mutation in KDS-1830C truncates a beta sheet, potentially impairing amylopectin binding and granule crystallization.
