Bacteria
Bacteria (; : bacterium) are ubiquitous, mostly free-living organisms often consisting of one Cell (biology), biological cell. They constitute a large domain (biology), domain of Prokaryote, prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit the air, soil, water, Hot spring, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and the nitrogen fixation, fixation of nitrogen from the Earth's atmosphere, atmosphere. The nutrient cycle includes the decomposition of cadaver, dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, suc ...

Bacterial Leaf Spot Of Peppers And Tomato
Bacterial leaf spot on peppers and tomatoes is caused by a gram-negative and rod-shaped bacterium in the genus ''Xanthomonas''.Thieme, Frank et al. 2005. Insights into Genome Plasticity and Pathogenicity of the Plant Pathogenic Bacterium ''Xanthomonas campestris'' pv. ''vesicatoria'' Revealed by the Complete Genome Sequence. J Bacteriol. 2005 November; 187(21): 7254–7266. It causes symptoms throughout the above-ground portion of the plant including leaf spots, fruit spots and stem cankers.University of Connecticut- Integrated Pest Management. 2012.

Xanthomonas Hortorum
''Xanthomonas hortorum'' is a plant pathogen. It includes the following pathovars: * pv. ''hederae'', common ivy and possibly other Araliaceae * pv. ''taraxaci'', '' Pelargonium peltatum'' * pv. ''carotae'', wild carrot * pv. ''pelargonii'', Kazakh dandelion * pv. ''vitians'', bacterial leafspot and headrot of lettuce, using the neopathotype of LMG 938 * pv. ''cynarae'', formerly ''Xanthomonas cynarae'', pathogenic on artichoke * pv. ''gardneri'', formerly ''Xanthomonas gardneri'' and briefly ''X. cynarae'' pv. ''gardneri'', bacterial leafspot of peppers and tomatoes (pathotype also causes BLS on lettuce surprisingly) The species was originally defined in 1995 as a grouping of pathovars ''hederae'', ''taraxaci'', ''carotae'', ''pelargonii'' from ''Xanthomonas campestris ''Xanthomonas campestris'' is a gram-negative, obligate aerobic bacterium that is a member of the Xanthomonadaceae, a family of bacteria that are commonly known for their association with plant disease.
