A force awakens: exploiting solar energy beyond photosynthesis.

abstract：:Medicago truncatula is a model legume plant that interacts symbiotically with Sinorhizobium meliloti, the alfalfa symbiont. This process involves a molecular dialogue between the bacterium and the plant. Legume roots exude flavonoids that induce the expression of a set of rhizobial genes, the nod genes, which are esse...
