Identification of Pseudomonas syringae pv. actinidiae as causal agent of bacterial canker of yellow kiwifruit (Actinidia chinensis Planchon) in central Italy
Journal of Phytopathology 157 (11-12), 768-770
Abstract: Angular, necrotic leaf spot, longitudinal cracks along the petiole, oozing and wilting of branches were observed during summer 2008 on Actinidia chinensis (yellow kiwifruit) cultivar Hort16A, cultivated in different orchards located the province of Latina (central Italy). Symptoms closely resembled those incited by Pseudomonas syringae pv. actinidiae on kiwifruit A. deliciosa. Isolates obtained from typical lesions were assessed by means of biochemical, pathogenicity and host range tests and compared with some Pseudomonas syringae pathovars by enterobacterial repetitive intergenic consensus (ERIC-PCR) analysis. The isolates belong to Pseudomonas LOPAT group Ia, incited the death of pot-cultivated A. chinensis cv. Hort 16A and A. deliciosa cv. Hayward plants in few days, but did not cause any symptoms to the other inoculated plant species. Upon ERIC-PCR analysis, all the isolates showed similarity with P. syringae pv. actinidiae NCPPB 3739, type-strain of the pathovar. This is the first report of this pathogen on A. chinensis in Italy and, as far as we currently know, in the world.
