What rhymes with pseudomonas syringae?
pseu·domonas syringae

Pseudomonas syringae is a rod shaped, Gram-negative bacterium with polar flagella. It is a plant pathogen which can infect a wide range of plant species, and exists as over 50 different pathovars, all of which are available to researchers via international culture collections such as the NCPPB, ICMP, and others. It is unclear whether these pathovars represent a single species. P. syringae is a member of the Pseudomonas genus, and based on 16S rRNA analysis, it has been placed in the P. syringae group. It is named after the lilac tree, from which it was first isolated. P. syringae tests negative for arginine dihydrolase and oxidase activity, and forms the polymer levan on sucrose nutrient agar. Many but not all strains secrete the lipodepsinonapeptide plant toxin syringomycin, and it owes its yellow fluorescent appearance when cultured in vitro on King's B medium to production of the siderophore pyoverdin. P. syringae also produce Ina proteins which cause water to freeze at fairly high temperatures, resulting in injury to plants. Since the 1970s, P. syringae has been implicated as an atmospheric "biological ice nucleator", with airborne bacteria serving as cloud condensation nuclei. Recent evidence has suggested that the species plays a larger role than previously thought in producing rain and snow. They have also been found in the cores of hailstones, aiding in bioprecipitation. These Ina proteins are also used in making artificial snow.
