Query: NC_006512:2789098 Idiomarina loihiensis L2TR, complete genome Lineage: Idiomarina loihiensis; Idiomarina; Idiomarinaceae; Alteromonadales; Proteobacteria; Bacteria General Information: This is the type strain for this organism, which was isolated from a hydrothermal vent at a depth of 1300 m from the Lo'ihi Seamount southeast of Hawaii. This organism grows optimally in salt concentrations of 7.5 to 10%. Genome comparison has suggested that the bacterium has maintained its amino acid transport and degradation systems but lost sugar transport and certain sugar metabolic genes suggesting that it lives on amino acids rather than sugars. This may be in keeping with the environment this organism grows in, which is at hydrothermal deep sea vents that are characterized by collections of proteinaceous particles. This organism may colonize these particles by producing exopolysaccharides.

General Information: This organism is found in the aphid Baizongia pistaciae. Aphid endosymbiont. It is believed that the Buchnera provide the essential nutrients the host lacks. Besides a nutritional co-dependence, due to a co-existence of millions of years, Buchnera have lost the ability to produce cell surface components such as lipopolysaccharides. This makes for an obligate endosymbiont relationship between host and Buchnera. Buchnera are prokaryotic cells which belong to the gamma-Proteobacteria, closely related to the Enterobacteriaceae family. Phylogenetic studies using 16S rRNA indicate that the symbiotic relationship was established around 200-250 million years ago. Since Buchnera are closely related to Escherichia coli and Haemophilus influenzae, comparative genomic studies can shed light on the evolutionary mechanisms of intracellular endosymbiosis as well as the different underlying molecular basis between organisms with parasitic behavior and symbionts.
