Other claims from this paper (10)

Observation Under ambient CO2, transgenic and wild-type lines did not differ in growth or grain yield.
Intervention effect Elevated CO2 increased wild-type rice growth and grain yield.
Intervention effect Elevated CO2 increased OsRab6a-OE growth and grain yield more than in wild type.
Intervention effect Elevated CO2 did not affect OsRab6a-RNAi growth or grain yield.
Intervention effect Elevated CO2 stimulated wild-type photosynthesis.
Intervention effect Elevated CO2 stimulated OsRab6a-OE photosynthesis more than wild type.
Intervention effect Elevated CO2 reduced vegetative-tissue iron in wild-type and transgenic lines.
Observation The CO2-induced iron decrease was smaller in OE plants than in WT and RNAi plants.
Observation Fe-acquisition genes were more highly expressed in OE lines under elevated CO2.
Mechanism The authors identify OsRab6a as a regulator of rice adaptation to elevated CO2 through photosynthesis and Fe accumulation.

Other claims from this paper (9)

Association The magnitude of the drought effect on soil fungi depended on the initial community.
Intervention effect Drought was associated with a decrease in soil fungal network connectivity.
Intervention effect Drought changed the dominant fungal taxa in soil.
Intervention effect Drought legacy reduced crop yield during the recovery period.
Intervention effect Drought legacy slowed soil decomposition rate 6 months after the drought.
Association The effect of drought on crop yield depended on the soil inoculum.
Intervention effect The legacy effect of drought on fungal communities was smaller in bulk soil than in rhizosphere soil.
Association Soil communities that were more diverse and fungal-rich recovered faster from drought.
Recommendation The authors conclude that watering of soils can alleviate the most acute drought stress on soil fungal communities.
