Other claims from this paper (8)
- Observation Lines with enlarged chloroplasts underperformed on most measured traits.
- Observation Lines with smaller and more numerous chloroplasts had similar efficiency to wild-type tobacco.
- Association Chloroplast size weakly affected leaf light absorptance and light profiles.
- Intervention effect Increasing chloroplast size decreased mesophyll conductance.
- Intervention effect Decreasing chloroplast size did not increase mesophyll conductance.
- Intervention effect Increasing chloroplast size reduced chloroplast movements.
- Intervention effect Increasing chloroplast size enhanced non-photochemical quenching.
- Recommendation The authors judged chloroplast size manipulation unlikely to raise photosynthetic efficiency or growth.
