Query: NC_013892:3278647 Xenorhabdus bovienii SS-2004 chromosome, complete genome
Lineage: Xenorhabdus bovienii; Xenorhabdus; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Insect pathogenic, facultatively anaerobic, non-spore forming Gram-negative bacterium. This genus is a group of insect pathogens which live in a mutualistic relationship with the soil nematode family Steinernematidae. Free-living, juvenile Steinernema spp. enter insect larvae through the digestive tract. They penetrate the larvae body cavity and release Xenorhabdus spp. into the hemolymph (blood). The bacteria multiply rapidly, killing the larvae, and providing suitable nutrient conditions for the growth and reproduction of the Steinernema spp. The nematode matures and reproduces. The new juveniles reassociate with Xenorhabdus spp. and are released into the soil.Xenorhabdus bovienii. Unlike Xenorhabdus nematophila, which is found in only in Steinernema carpocapsae, Xenorhabdus bovienii is associated with several different species of Steinernema.
Subject: NC_004578:934867 Pseudomonas syringae pv. tomato str. DC3000, complete genome
Lineage: Pseudomonas syringae group genomosp. 3; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria
General Information: While pathogenic on Arabidopsis thaliana, it is mainly characterized as causing bacterial speck disease on tomato plants, which has a large economic impact. This organism is mainly endophytic and is a poor colonizes of plant surfaces but can multiply within the host. Bacteria belonging to the Pseudomonas group are common inhabitants of soil and water and can also be found on the surfaces of plants and animals. Pseudomonas bacteria are found in nature in a biofilm or in planktonic form. Pseudomonas bacteria are renowned for their metabolic versatility as they can grow under a variety of growth conditions and do not need any organic growth factors. This species includes many plant pathogens of important crops, which makes it a model organism in plant pathology. Its natural environment is on the surface of plant leaves and it can withstand various stressful conditions, like rain, wind, UV radiation and drought. It can colonize plants in a non-pathogenic state and can rapidly take advantage of changing environmental conditions to induce disease in susceptible plants by shifting gene expression patterns.
