Descripción
Rhizobium leguminosarum bv. viciae (Rlv) is an ?-proteobacterium commonly found in association with Vicia, Pisum, Lens or Lathyrus. This symbiosis is based on the exchange of plant carbon compounds to bacteroids in return of nitrogen molecules fixed in nodules (Gage et al, 2004). Thus, it is not only interesting from the biological point of view, but also for sustainable agriculture in order to reduce the amount of nitrogen fertilizers. Rlv strains are able to infect, induce nodule and fix nitrogen in any of these legumes; however, there are evidences that show differential expression in some Rlv proteins depending of the host (Brito et al, 2008). Proteomic analysis and ITRAQ quantification from Rlv UPM 791 bacteroids induced in lentil and pea plants showed a significant number of protein whose expression were found to differ in bacteroids from each host. We have focused in six host-dependent proteins: i) two protein involved in metabolic adjustment (c189 encode a diaminobutyrate 2-oxoglutarate transaminase relative to a route derived from tricarboxylic acid cycle, and c190 that is similar to a biotin carboxylase); ii) three sHSPs (small Heat Shock Protein), hsp20, hspD2, hspD3; iii) and an USP (Universal Stress Protein), chr2011.
