The production of peptide siderophores and the variation in siderophore production among strains of Pseudomonas syringae and Pseudomonas viridiflava were investigated. An antibiose test was used to select a free amino acid-containing agar medium favorable for production of fluorescent siderophores by two P. syringae strains. A culture technique in which both liquid and solid asparagine-containi...

Pseudomonas syringae pv. panici is a phytopathogenic bacterium causing brown stripe disease in economically important crops worldwide. Here, we announce the draft genome sequence of Pseudomonas syringae pv. panici LMG2367 to provide further valuable insights for comparison of the pathovars among species Pseudomonas syringae.

A polymerase chain reaction (PCR) protocol that can be used to distinguish Pseudomonas syringae pv. tagetis from other P. syringae pathovars, including those that induce apical chlorosis in several plants of the Asteracaea family and in pea, and closely related P. savastanoi pathovars was developed based on DNA sequences from P. syringae pv. tagetis that are required for tagetitoxin synthesis. ...

Pseudomonas syringae pv. lapsa is a pathovar of Pseudomonas syringae that can infect wheat. The complete genome of P. syringae pv. lapsa strain ATCC 10859 contains a 5,918,899-bp circular chromosome with 4,973 coding sequences, 16 rRNAs, 69 tRNAs, and an average GC content of 59.13%. The analysis of this genome revealed several gene clusters that are related to pathogenesis and virulence.

Pseudomonas syringae pv. actinidifoliorum causes necrotic spots on the leaves of Actinidia deliciosa and Actinidia chinensis. P. syringae pv. actinidifoliorum has been detected in New Zealand, Australia, France and Spain. Four lineages were previously identified within the P. syringae pv. actinidifoliorum species group. Here, we report the draft genome sequences of five strains of P. syringae p...

The molecular features of Pseudomonas syringae pv. actinidiae strains isolated in Korea were compared with strains isolated in Japan and Italy. Sequencing of eight P. syringae pv. actinidiae and three P. syringae pv. theae strains revealed a total of 44 single nucleotide polymorphisms across 4,818 bp of the concatenated alignment of nine genes. A multiplex PCR assay was developed for the detect...

Strains of the plant pathogen Pseudomonas syringae are commonly found in the phylosphere and are able to infect a number of agriculturally important crops. Here, we report a high-quality draft genome sequence of Pseudomonas syringae pv. syringae B301D-R, isolated from pears, which is a model strain for phytotoxin research in P. syringae.
