Proteomic changes may lead to yield alteration in maize under carbon dioxide enriched condition.

ABSTRACT: In the present study, the effect of elevated CO₂ on growth, physiology, yield and proteome was studied on two maize (Zea mays L.) varieties grown under Free-air CO₂ enrichment. Growth in high CO₂ (530 ppm) did not affect either photosynthesis or pigment contents in both varieties. Reduced MDA content, antioxidant and antioxidative enzymes levels were observed in both varieties in response to high CO₂. PEHM-5 accumulated more biomass than SMH-3031 under eCO₂. PEHM-5 also had more seed starch and total soluble sugar than SMH-3031. However, SMH-3031 had increased number of seed per cob than PEHM-5. Interestingly, thousand seed weight was significantly increased in PEHM-5 only, while it was decreased in SMH-3031 under eCO₂
