Infection mechanism of black spot pathogen in Japanese pear



Infection mechanism of black spot pathogen in Japanese pear



Acta Horticulturae (587): 623-630



In a study conducted to determine the infection mechanism of black spot (Alternaria alternata) in Japanese pear (Pyrus pyrifolia), results showed that pathogenicity was equal on the leaf surfaces of susceptible and resistant cultivars, but penetration was detected only in susceptible leaves. The pathogen released a host-specific toxin (AK-toxin) immediately after spore germination which was toxic only to susceptible cultivars.
