Other claims from this paper (19)
- Intervention effect NIL-qSBM1Kasalath increased aboveground biomass and plant height relative to NPB.
- Intervention effect NIL-qSBM1Kasalath increased grain number per panicle relative to NPB.
- Intervention effect NIL-qSBM1Kasalath increased grain yield per plant relative to NPB.
- Intervention effect NIL-qSBM1Kasalath decreased thousand grain weight relative to NPB.
- Observation SBM1 knockout mutants showed similar but greater trait variation than the NIL.
- Observation SBM1 overexpression plants showed trait changes opposite to the NIL and knockout lines.
- Intervention effect The NPB allele complementation restored the knockout phenotype.
- Intervention effect The Kasalath allele complementation partly restored the knockout phenotype.
- Observation SBM1 expression occurred in several organs with preferential expression in roots.
- Observation SBM1 GFP localized to the plasma membrane.
- Observation Three principal SBM1 haplotypes were identified among 1140 accessions.
- Observation HapA was widespread in japonica whereas HapB and HapC were mainly in indica.
- Observation HapB was the most productive of the three haplotypes in collected rice accessions.
- Intervention effect Knockout increased and overexpression decreased seedling biomass relative to NPB across NH4NO3 conditions.
- Intervention effect In a field trial NIL-SBM1Kasalath increased plant height, grain number and plot yield at both nitrogen rates.
- Observation NIL-SBM1Kasalath had significantly higher nitrogen use efficiency.
- Observation NIL-SBM1Kasalath had higher nitrogen uptake, transport and nitrate reductase activity than NPB.
- Observation SBM1 interacted with OsMPK6, supported by yeast screening and follow up assays.
- Mechanism SBM1 knockout effects on biomass and grain number genetically depended on OsMPK6.
