The International Society for Molecular Plant-Microbe Interactions (IS-MPMI) is comprised of members from more than 30 countries who research molecular aspects of microorganisms interacting with plants and the consequences of such interactions. Disciplines represented by IS-MPMI members include microbiology, nematology, plant pathology, plant breeding, and many more. Introduction. Pseudomonas syringae is one of the pre‐eminent models for the exploration of plant–microbe interactions in both natural and laboratory systems. The species has played a central role in seminal studies and publications, including the development of the guard hypothesis (Dangl and Jones, ) and the zig–zag model (Jones and Dangl, ) of plant immunity.

Introduction. Pseudomonas syringae is a Gram-negative bacterial phytopathogen responsible for worldwide disease on many crop e a collectively broad pathogenic range for the species, individual isolates of P.
syringae display pathogenic potential on a limited set of plant species and either elicit immune responses, or simply fail to thrive on alternative species –.Cited by: Plasmids are transmissible, extrachromosomal genetic elements that are often responsible for environmental or host-specific adaptations.
In order to identify the forces driving the evolution of these important molecules, we determined the complete nucleotide sequence of the five-plasmid complement of the radish and Arabidopsis pathogen Pseudomonas syringae pv.
maculicola ES and conducted Cited by: Pseudomonas syringae is a common foliar bacterium responsible for many important plant diseases. We studied the population structure and dynamics of the core genome of P. syringae via multilocus sequencing typing (MLST) of 60 strains, representing 21 pathovars and 2 nonpathogens, isolated from a variety of plant hosts.
Seven housekeeping genes, dispersed around the P. syringae genome Cited by: Pseudomonas isolates, much of the phylogenetic, ecological, and host diversity for this plant pathogen remains unexplored.
We provide a phylogenetically comprehensive genomic view of P. syringae with a focus on TTE repertoire evolution. We analyzed data from draft or complete genome sequences of. The first wave of Pseudomonas syringae next-generation genomic studies has revealed insights into host-specific virulence and immunity, genome dynamics and evolution, and genetic and metabolic specialization.
These studies have further enhanced our understanding of type III effector diversity, identified an atypical type III secretion system (T3SS) in a new clade of nonpathogenic P.

Pseudomonas syringae pv. phaseolicola, a gram-negative bacterial plant pathogen, is the causal agent of halo blight of bean. In this study, we report on the genome sequence of P. syringae pv. phaseolicola isolate A, which encodes 5, open reading frames (ORFs) on one circular chromosome (5, bp) and two plasmids (, bp bp).

Biotechnol Bioeng. 90 (1)– Pseudomonas syringae is a highly diverse bacterial species complex capable of causing a wide range of serious diseases on numerous agronomically important crops.
We examine the evolutionary relationships of agricultural and environmental strains using whole-genome sequencing and evolutionary genomic analyses.

Table 1 Genome features for published Pseudomonas syringae genomes Strain Host PG a Genome Length (bp) %GC #ORFs Reference Pto DC Tomato 1 chromosome 6, 5, (8). Abstract. Genomic study of the genus Pseudomonas depends on knowledge of not only chromosomal sequences of the major species comprising the genus, but also the mobile genetic elements (MGEs) that carry key determinants within and between species.
MGEs include plasmids that replicate autonomously in the cytoplasm of their host, temperate phage that can coexist with their host as prophage either. For example Ralstonia solanacearum encodes 72 T3SE [15, 16•] while Pseudomonas syringae pv. tomato strain DC expresses 28 T3SE.
An understanding of how the bacteria are evolving to overcome host resistance and what is driving this evolution is crucial for designing robust agricultural strategies to maintain healthy crop plants. Given the large size of the P. syringae pan-genome, the fact that some strains have acquired large plasmids, and the relatively high frequency of horizontal gene transfer in the P.
syringae species complex (Baltrus et al., ; Dillon et al., ), we expect there to be some variation in genome size and coding content of different strains.

Environ Microbiol. 19. By clustering Pseudomonas 16S rDNA reads at 99% sequence identity, we could distinguish 56 OTUs (Figure 1B). The 99% threshold resulted in OTU patterns more congruent with a subsequently derived core genome-phylogeny than the more widely used 97% sequence identity ().Thirteen of the 56 OTUs, including the most abundant OTU, OTU5, were classified as P.
