Query: NC_009482:822716 Synechococcus sp. RCC307 chromosome, complete genome
Lineage: Synechococcus; Synechococcus; Synechococcaceae; Chroococcales; Cyanobacteria; Bacteria
General Information: Marine Synechococcus and Prochlorococcus are the most abundant photosynthetic organisms on earth and between them account for about half of the world's photosynthesis. RCC307 is an oceanic Synechococcus strain which presents great phylogenetic interest because trees obtained using its 16S RNA gene seem to indicate that it is rooted at the base of the radiation of marine cyanobacteria. This strain was isolated from seawater taken at a depth of 15 meters from the Mediterranean Sea.
Subject: NC_007005:830467 Pseudomonas syringae pv. syringae B728a, complete genome
Lineage: Pseudomonas syringae; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria
General Information: This strain is the causal agent of brown spot disease on beans. It was isolated from a snap bean leaflet in Wisconsin, USA. Plant pathogen. 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.
