Resumo

This is the first study to detect the effect of calcium ions on the activity of transmembrane adenylyl cyclase (tmAC), the key enzyme of the adenylyl cyclase signaling system, under normal conditions and after a short-term exposure to exopolysaccharides (EPS) of the bacterial ring rot pathogen Clavibacter michiganensis ssp. sepedonicus (Cms). After the treatment of the roots of plants with the Cms EPS, the response to Ca2+ changed: the activity of the tmAC of plants of the resistant cultivar significantly increased, whereas in the cells of the susceptible cultivar it remained unchanged.
