(13)C/(12)C isotope labeling to study carbon partitioning and dark respiration in cereals subjected to water stress.

Despite the relevance of carbon (C) loss through respiration processes (with its consequent effect on the lower C availability for grain filling), little attention has been given to this topic. Literature data concerning the role of respiration in cereals are scarce and these have been produced using indirect methods based on gas-exchange estimations. We… (More)
