Query: NC_013722:2476236 Xanthomonas albilineans, complete genome
Lineage: Xanthomonas albilineans; Xanthomonas; Xanthomonadaceae; Xanthomonadales; Proteobacteria; Bacteria
General Information: This bacterium causes the economically important leaf scald disease in sugar cane. Xanthomonas albilineans produces a potent toxin, albicidin, which is responsible for the characteristic whitening of sugar cane leaves and stunted plant growth.
Subject: NC_006510:2044347 Geobacillus kaustophilus HTA426, complete genome
Lineage: Geobacillus kaustophilus; Geobacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: Geobacillus kaustophilus strain HTA426 was first isolated from deep sea sediment of the Mariana Trench in the Pacific Ocean and belongs to a closely related group of thermophilic Bacillus spp. Members of this genus were originally classified as Bacillus. Recent rDNA analysis and DNA-DNA hybridization studies using spore-forming thermophilic subsurface isolates provided enough evidence to define the phylogenetically distinct, physiologically and morphologically consistent taxon Geobacillus. Geobacillus species are chemo-organotrophic, obligately thermophilic, motile, spore-forming, aerobic or facultatively anaerobic. This organism was compared with mesophilic Bacillus spp. to identify genome characteristics and specific genes related to thermophilia. Analysis of the amino acid compositions showed clear differences between Geobacillus kaustophilus and the mesophilic bacilli. In addition, the higher G+C content in Geobacillus kaustophilus rRNA also appears correlated to thermophilia. In addition, tRNA modification by the Geobacillus kaustophilus specific tRNA methyltransferases probably aids in the thermoadaptation of this organism.
