Proteins from legumes possess the highest sustainability because, among other reasons, legume plants have positive impact on soil fertility due to their ability to fix nitrogen via rhizobial symbioses. Medicago truncatula was chosen as a model for legumes because it is diploid, with a relatively small genome (450–550 Mb), self-fertile, relatively easy to transform, and it has a short generation time. In the last years several mutant collections became available in both Europe and USA, based on different strategies: chemical mutagenesis (TILLING); deletion mutagenesis (fast-neutron bombardment and -rays); insertional mutagenesis (transposons such as Tnt1) (Porceddu et al, 2008; Tadege et al., 2009, Rogers et al., 2009 ). Part of these collections were produced in Italy and used for isolating mutants of interest related to traits of practical relevance, in particular a key gene involved in saponin biosynthesis was identified. The possibility to speed up knowledge of the genetic control of traits of agronomic interest and translate such knowledge to crop legumes via different means will be discussed.
