Short description of contents:

The symbiotic association with N-fixing bacteria facilitates the growth of leguminous plants under nitrogen-limiting conditions. The establishment of the symbiosis requires signal exchange between the host and the bacterium, which leads to the formation of root nodules, inside which bacteria are hosted. The formation of nodules is controlled through local and systemic mechanisms which involves root-shoot communication. Our study was aimed at investigating the proteomic changes occurring in shoots and concomitantly in roots of Medicago truncatula at an early stage of Sinorhizobium meliloti infection. The principal systemic effects consisted in alteration of chloroplast proteins, induction of proteins responsive to biotic stress and changes in proteins involved in hormonal signaling and metabolism. The most relevant local effect was the induction of proteins involved in the utilization of photosynthates and C-consuming processes (such as sucrose synthase and fructose-bisphosphate aldolase). In addition, some redox enzymes such as peroxiredoxin and ascorbate peroxydase showed an altered abundance. The analysis of local and systemic proteome changes suggests the occurrence of a stress response in the shoots and the precocious alteration of energy metabolism in roots and shoots. Furthermore, our data support the hypothesis that ABA and ethylene participate in the communicative network between root and shoot in the control of rhizobial infection.
