Other claims from this paper (13)
- Observation OsPUKI was predominantly expressed in rice stem, panicle, leaf sheath, embryo and sprouting seed germ.
- Intervention effect OsPUKI knockout reduced rice grain yield per plant by 35.97-51.66%.
- Intervention effect OsPUKI knockout reduced rice thousand grain weight by 3.37-6.20%.
- Intervention effect OsPUKI knockout reduced rice grain width and thickness.
- Observation Rice ospuki lines had narrower spikelet hull cells.
- Observation Rice ospuki mutants had altered starch gelatinization properties.
- Observation Rice ospuki mutants had elevated seed storage protein content.
- Observation Rice ospuki mutants had elevated Asp, Glu and Tyr content.
- Observation Rice ospuki mutants had elevated Leu, Val and Phe content.
- Observation Starch synthesis gene transcripts decreased significantly in ospuki rice.
- Observation Protein and amino acid metabolism gene expression changed significantly in ospuki rice.
- Mechanism The authors infer that OsPUKI regulates grain size and weight through spikelet hull cell proliferation and expansion.
- Mechanism The authors infer that OsPUKI affects rice yield and quality through storage substance accumulation.
