Interpretive Summary: Xylella fastidiosa is a slow growing, xylem inhabiting, nutritionally fastidious and insect-transmitted bacterium. The bacterium not only causes devastating Pierce’s disease of grapevine in the US, citrus variegated chlorosis and coffee leaf scorch in Brazil, and olive quick decline syndrome in Italy, but also bacterial leaf scorch and decline in many economically important landscape trees and shrubs including oak, elm, sycamore, mulberry, and oleander. Although at least 65 genome sequences of X. fastidiosa strains have been determined so far, such information has only been obtained for mulberry, sycamore, and oak strains of X. fastidiosa in landscape trees. We report here the draft genome sequence for the elm strain of X. fastidiosa obtained from American Type Culture Collection and originally isolated from a symptomatic tree of American elm grown in Washington D.C. The genome information could provide biological insights into the plasticity, nutritional requirements, pathogenicity, and bacterial-host interactions of the landscape tree strains of X. fastidiosa. It may also be useful in developing specific detection methods for this important bacterium.

Technical Abstract: We report here the draft genome sequence of Xylella fastidiosa strain ATCC35873, obtained from American Type Culture Collection and originally isolated from a symptomatic tree of American elm grown in Washington D.C. The ATCC35873 genome contains 2,454,216 bp and has a G+C content of 51.68 %.
