The kiwifruit bacterial canker pathogen,  Pseudomonas syringae  pv.  actinidiae  (Psa), causes enormous economic damages in many kiwifruit producing countries. In 2015, biovar 6, the novel biovar of Psa, was found in Nagano Prefecture, Japan. The genomes of two representative strains of biovar 6 (MAFF 212134 and MAFF 212141) were sequenced and analysed, indicating that their genomes are the most similar to that of biovar 3 among the known Psa biovars, based on average nucleotide identity analysis. Biovar 3 has neither the phaseolotoxin synthesis gene cluster nor the coronatine synthesis gene cluster, whereas biovar 6 has both clusters and produces both phytotoxins. We found that biovar 6 possesses 29 type III secreted effector (T3SE) genes, among which  avrRps4  and  hopBI1  are unique to biovar 6. The expression of T3SE genes and two phytotoxin synthesis gene clusters of biovar 6 during the early stages of host infection was investigated using RNA-Seq analysis, showing that these genes could be grouped into three categories: constantly expressed genes, constantly suppressed genes, and temporarily induced genes. A PCR assay was established to differentiate biovar 6 strains from the other Psa biovars and the closely related pathovar, pv.  actinidifoliorum , by using  avrRps4  as a biovar 6-specific marker gene.
