Type III secretion gene repertoires in strains of Pseudomonas syringae. Results for Pseudomonas syringae pv. actinidiae (Psa) bv. 1, Psa bv. 3 and Psa bv. 4 were compressed as the results were identical for all the strains analysed (all the genomes available in GenBank). Strains USA0007 and CC1544 were isolated from river headwaters. Other strains indicated include MAFF 302280 (P. syringae pv. morsprunorum), NCPPB 2598 (P. syringae pv. theae), BPIC 631 (P. syringae pv. avellanae), DC3000 (P. syringae pv. tomato), B728a (P. syringae pv. syringae) and Pph1448a (P. syringae pv. phaseolicola). Black boxes indicate that the genes were found in full length, white boxes indicate the absence of the genes and grey boxes indicate that the genes were truncated. The origin of strains and their biovar affiliation are indicated with colour: light blue for Psa bv. 3, turquoise for Psa bv. 1, dark blue for Psa bv. 4, brown for strains isolated from woody hosts, green for strains isolated from herbaceous hosts and red for the environmental strains.
