Differential Expression of Proteins in Apple Following Inoculation With Erwinia Amylovora

Molecular response of resistant and susceptible apple genotypes to Erwinia amylovora infection

“…It is expressed in a number of plants infected with various pathogens (Rivera et al 2002), but also during induction of systemic acquired resistance with abiotic elicitors like salicylic acid or acibenzolar-S-methyl (Brisset et al 2000). Overexpression of this gene was observed previously in apples infected with E. amylovora by Venisse et al (2002) and Heyens et al (2006). The mode of action of β-1,3-glucanase against pathogen infection is not clear.…”

“…Bacterial infection leads to a range of defence responses in planta, ranging from an induction of lipid peroxidation, a change in ion fluxes and cell wall reinforcement (Nicaise et al 2009), emission of volatiles (Bent et al 1992), accumulation of phytoalexins (Huttner et al 2010), activation of pathogenesis-related proteins (Heyens et al 2006), an increase of secondary metabolites (Fischer et al 2007;Gayler et al 2004;Milcevicova et al 2010) and a shift in plant hormone balances (Robert-Seilaniantz et al 2007). Probably one of the earliest responses to a pathogen infection, is a rapid increase of reactive oxygen species (ROS), released into the apoplast of primarily infected plant cells (Baker and Orlandi 1995;Bolwell and Wojtaszek 1997).…”
