	Brenneria Salicis ''Brenneria salicis'' is a Gram-negative bacterium that is pathogenic on plants. The bacterium is known to cause 'watermark disease' in willow (''Salix'' ssp.) trees. Watermark disease affects infected trees by occluding the xylem Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of xylem is to transport water from roots to stems and leaves, but it also transports nutrients. The word ''xylem'' is derived from ... vessels, impeding circulation. Early signs of the disease are wilting or dried-out, dead leaves on intermittent branches throughout the tree's crown. Cross sections from affected branches show a watery, transparent discoloration to an orange-brown staining in the wood. Cross sections of a killed tree's main stem are blanched completely white.Willow Resistance to the Watermark Disease, author: M. Steenackers.

	Enterobacterales Enterobacterales is an order of Gram-negative, non-spore forming, facultatively anaerobic, rod-shaped bacteria with the class Gammaproteobacteria. The type genus of this order is ''Enterobacter.'' The name Enterobacterales is derived from the Latin term ''Enterobacter'', referring the type genus of the order and the suffix "-ales", an ending used to denote an order. Together, Enterobacterales refers to an order whose nomenclatural type is the genus ''Enterobacter''. Historical Identification and Systematics Enterobacterales was proposed in 2005 under the name "Enterobacteriales". However, the name "Enterobacteriales" was not validated according to the rules of the ''International Code of Nomenclature of Prokaryotes,'' thus it lacked standing in nomenclature, so the name was written in parentheses. "Enterobacteriales" was a monotypic order, containing only the family '' Enterobacteriaceae'', and shared its type genus ''Escherichia''.NCBEnterobacteralesaccessed 9 Mar 2013 The ...

	Erwinia ''Erwinia'' is a genus of Enterobacterales bacteria containing mostly plant pathogenic species which was named for the famous plant pathologist, Erwin Frink Smith. It contains Gram-negative bacteria related to ''Escherichia coli'', ''Shigella'', ''Salmonella'', and ''Yersinia''. They are primarily rod-shaped bacteria. Many infect woody plants. A well-known member of this genus is the species '' E. amylovora'', which causes fire blight on apples, pears, and other Rosaceae crops; ''E. tracheiphila'', though, causes bacterial wilt of cucurbits. Other familiar species, such as '' E. carotovora'' (another major cause of plant diseases), are more distantly related to the fire blight bacterium, and have been moved to genera ''Brenneria'', ''Dickeya'', and '' Pectobacterium''. ''Erwinia aphidocola'' and ''E. persicina'' species were both observed to be present within the floral nectar microbial community of seven different orchid (''Epipactis'') flower species.

picture info	Bacteria Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of 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 soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of 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, such as hydrogen sulphide and methane, to energy.
