Antibacterial mechanism of forsythoside A against Pseudomonas syringae pv. actinidiae
Microbial Pathogenesis, 2022In this study, we investigated the antibacterial mechanism of forsythoside A against the kiwifruit canker pathogen, which provided the theoretical basis for the prevention and control of canker disease and the development of plant-based fungicides. The pathogenic bacteria were isolated from kiwifruit diseased tissues and the specific primers Psa_A1 F2 ...

SURVIVAL OF PSEUDOMONAS SYRINGAE PV. ACTINIDIAE IN THE ENVIRONMENT
Acta Horticulturae, 2015Pseudomonas syringae is a group of bacteria that can survive in the environment outside their host plants, the environment constituting a reservoir for the pathogen. To determine whether Pseudomonas syringae pv. actinidiae (Psa), the causal agent of bacterial canker of kiwifruit, could survive in the environment, and where in the environment it could ...

Pseudomonas syringae pv. Actinidiae (Psa), the causal agent of the bacterial canker of kiwifruit, uses leaves as an entry site to colonize plants. Upon leaf attack, this Gram-negative bacterium reaches systemically the plant shoot in a week. A combined approach based on two-dimensional gel electrophoresis (2-DE) and nano-scale liquid chromatographic ...

Molecular signalling in Pseudomonas syringae pv. actinidiae
Acta Horticulturae, 2018Bacterial communication is a complex phenomenon that involves a heterogeneous class of compounds acting as signal molecules and receptors that specifically recognize some of the signal molecules. This communication system occurs between bacteria of the same species, bacteria of different species and also between bacteria and eukaryotes; it affects ...

PSEUDOMONAS SYRINGAE pv. ACTINIDIAE IN NEW ZEALAND
Journal of Plant Pathology, 2012There are several populations of Pseudomonas syringae pv. actinidiae (Psa) that differ in virulence, in genetic characteristics, and in phenotypic characters. Primary concern is with highly virulent strains, here called Psa –V. They cause most damage in gold fruit cultivars of Actinidia chinensis.

Insect-mediated vectoring ofPseudomonas syringaepv.actinidiae
Acta Horticulturae, 2018From 2008, kiwifruit production and the total cultivated area decreased considerably, due to the pandemic spread of the bacterial canker caused by Pseudomonas syringae pv. actinidiae (Psa). This bacterium is able to infect host plants via natural openings or wounds, such as those caused by sucking insects.

Photoinactivation of Pseudomonas syringae pv. actinidiae in kiwifruit plants by cationic porphyrins
Planta, 2018The studied cationic porphyrins formulation allows an effective photoinactivation of Pseudomonas syringae pv. actinidiae in kiwifruit leaves under sunlight irradiation, without damaging the plant. Pseudomonas syringae pv. actinidiae (Psa) is a Gram-negative phytopathogenic bacterium responsible for canker on kiwifruit plant.
