Verbatim
e0“Fe concentrations in vegetative tissues and the grain of the WT and transgenic plants were reduced by e[CO2], and the magnitude of the decrease was lower in the OE plants than in the WT and RNAi plants.”
t0“A rice small GTPase, Rab6a, is involved in the regulation of grain yield and iron nutrition in response to CO2 enrichment”

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 grain 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.
