    Differences in rhizosphere carbon-partitioning among plant species of different families

    Interspecific variations in carbon (C) allocation and partitioning in the rhizosphere were investigated on 12 Mediterranean species belonging to different family groups (grasses, legumes, non-legume forbs) and...

    Towards a better understanding of carbon flow in the rhizosphere: a time-dependent approach using carbon-14

     Controversies exist in interpreting rhizosphere C flow obtained by different 14CO2 labelling methods. However, there is a need for the standardisation of methods in order to be able to compare values obtained fo...

    Why and how to estimate the cost of symbiotic N2 fixation? A progressive approach based on the use of14C and15N isotopes

    The process of symbiotic nitrogen fixation, though of obvious advantage to legumes in situations in which nitrogen is limiting, results in substantial penalty to the host plant in terms of cost of maintenance,...
