Photosynthetic flexibility in maize exposed to salinity and shade

Sharwood, Robert; Sonawane, Balasaheb V.; Ghannoum, Oula


C4 photosynthesis involves a close collaboration of the C 3 and C4 metabolic cycles across the mesophyll and bundlesheath cells. This study investigated the coordination of C4 photosynthesis in maize plants subjected to two salinity (50 and 100 mM NaCl) treatments and one shade (20% of full sunlight) treatment. Photosynthetic efficiency was probed by combining leaf gas-exchange measurements with carbon isotope discrimination and assaying the key carboxylases [ribulose-1,5- bisphosphate...[Show more]
