Effects of ammonia and pH on the relative expressions of genes involved in the pathogenicity process. Expressions were analyzed of: polygalacturonase (PG), Mep2, Copper amine oxidase (CuAO), ACC deaminase, PacC, and pectate lyase A (PelA). a Samples from the leading edge of infection in apples treated with exogenous NH4Cl at 0 and 22 μM, according to Barad et al. [8]; b Samples grown at pH 4 or pH 7, for 3 h in shaking secondary media (SM)
