Other claims from this paper (7)
- Intervention effect Thirteen bacterial isolates from kiwifruit canker reproduced canker-like symptoms when inoculated on Hayward, and the inoculated bacteria were re-isolated.
- Observation The bacterium was identified as Pseudomonas syringae pv. actinidiae by physiological tests, PCR assays and MLSA.
- Observation The novel bacterium differs from the four known biovars (1, 2, 3, 5) of P. syringae pv. actinidiae.
- Observation The novel biovar 6 produces both phaseolotoxin and coronatine, a combination not previously known in plant pathogenic bacteria.
- Observation Biovar 6 is closely related to biovar 1 and biovar 3.
- Observation Biovar 6 carries the phaseolotoxin and coronatine biosynthetic gene clusters.
- Recommendation The authors recommend against using the phaseolotoxin and coronatine genes as markers to detect or discriminate biovar 1 and biovar 2.
