- Intervention effect Aberrant RISBZ1 splice isoforms were undetectable in three edited lines under normal and heat conditions.
- Intervention effect Under normal conditions, major agronomic traits generally did not differ significantly between edited lines and WT.
- Intervention effect Line #5-2 had a slight reduction in grain number per panicle under normal conditions.
- Intervention effect Line #3-1 had a 4.2% increase in grain weight relative to WT.
- Intervention effect Line #5-1 had a 3.6% increase in grain weight relative to WT.
- Intervention effect Line #5-2 had 10.5% lower grain weight relative to WT.
- Observation Lines #3-1 and #5-1 had longer grains, whereas #5-2 had narrower grains.
- Intervention effect All three lines showed no significant changes in chalky grain rate or degree under normal conditions.
- Intervention effect Under heat stress, WT grain weight fell by 10.4% relative to normal conditions.
- Intervention effect Under heat stress, #3-1 showed a smaller, 4.7% grain weight reduction.
- Intervention effect Under heat stress, #5-1 showed a smaller, 4.1% grain weight reduction.
- Intervention effect Under heat stress, #3-1 and #5-1 had greater grain weight than WT.
- Intervention effect Under heat stress, #3-1 had 9.5% higher grain setting rate than WT.
- Intervention effect Under heat stress, #5-1 had 10.6% higher grain setting rate than WT.
- Intervention effect Under heat stress, #3-1 grain yield per plant rose 12.0%.
- Intervention effect Under heat stress, #5-1 grain yield per plant rose 11.7%.
- Intervention effect Edited lines had lower chalky grain rates and chalkiness degrees than WT under heat stress.
- Observation In #3-1 and #5-1, 19 of 21 tested genes were less downregulated or not downregulated under heat than in WT.
- Observation RISBZ1 mRNA nuclear export efficiency decreased in #5-2.
