Fig. 3From: G protein γ subunit qPE9-1 is involved in rice adaptation under elevated CO2 concentration by regulating leaf photosynthesisGrowth of wild-type rice and transgenic lines under aCO2 and eCO2. Seedlings were grown under aCO2 (400 ppm) or eCO2 (800 ppm) in growth chambers for 4 weeks. (A) Growth phenotypes of WT, RNAi lines and OE lines of qPE9-1 under aCO2 or eCO2 for 4 weeks. Bar: 10 cm. (B, C and D) Shoot dry weight, root dry weight and total dry weight of WT, RNAi lines and OE lines of qPE9-1 grown under aCO2 or eCO2 for 4 weeks. Values are means ± SD (n = 5); different letters indicate significant differences (P < 0.05)Back to article page
