On the relationship between C and N fixation and amino acid synthesis in nodulated alfalfa (Medicago sativa)

Published in Functional Plant Biology 41 (4) : 331-341, 2014 Molero, G.; Tcherkez, G.; Araus, J.L.; Nogues, S. Legumes such as alfalfa (Medicago sativa L.) are vital N2-fixing crops accounting for a global N2 fixation of ~35 Mt N year–1. Although enzymatic and molecular mechanisms of nodule N2 fixation...

Relative contribution of shoot and ear photosynthesis to grain filling in wheat under good agronomical conditions assessed by differential organ Delta13C

Published in Journal of Experimental Botany, 2014  Sanchez-Bragado, R.; Molero, G.; Reynolds, M.P.; Araus, J.L.  During grain filling in C3 cereals, the shoot (particularly the flag leaf) and the ear are believed to play major roles as sources of assimilates. However, both the cost and the intrusive...
