Rhizobium-made Nod factors induce rapid changes in both Ca(2+) and gene expression. Mutations and inhibitors that abolish Nod-factor-induced Ca(2+) spiking block gene induction, indicating a specific role for Ca(2+) spiking in signal transduction. We used transgenic Medicago truncatula expressing a "cameleon" Ca(2+) sensor to assess the relationship between Nod-factor-induced Ca(2+) spiking and the activation of downstream gene expression. In contrast to ENOD11 induction, Ca(2+) spiking is… CONTINUE READING
