Resumen:
Competition for nodulation is a complex problem where bacterial adhesins, which are required for root
colonization, may play a role. However, the possible influence of adhesins on competitiveness was
scarcely studied. In this work, the Rhizobium leguminosarum bv trifolii adhesion protein RapA1 was
overproduced from a pHC60-derived plasmid and expressed in R200 strain. When an overproducing
strain and a control-carrying empty vector were co-inoculated on clover plants, a positive effect of RapA1
on competition for nodule occupation was observed. Therefore, optimization of RapA1 expression may
be considered for improvement of rhizobial competitiveness.
