Query: NC_012724:829830 Burkholderia glumae BGR1 chromosome 1, complete genome Lineage: Burkholderia glumae; Burkholderia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria General Information: Burkholderia glumae causes seedling rot and panicle blight of rice. Panicle blight is a significant problem in the southern USA during unusually warm growing seasons. Infection of rice with Burkholderia glumae causes sterility, or abortion, of the rice kernels, and may inhibit seed germination. Burkholderia glumae also produces an industrially important extracellular lipase.

General Information: This strain is found in the pea aphid, Acyrthosiphon pisum.Aphid endosymbiont. Almost all aphids contain maternally transmitted bacteriocyte cells, which themselves contain bacteria called Buchnera. The aphids live on a restricted diet (plant sap), rich in carbohydrates, but poor in nitrogenous or other essential compounds. 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.
