RT Journal Article SR Electronic T1 Mycoplasmalike Organisms as Causes of Slow Growth and Decline of Trees and Shrubs JF Arboriculture & Urban Forestry (AUF) JO JOA FD International Society of Arboriculture SP 176 OP 189 DO 10.48044/jauf.1994.033 VO 20 IS 3 A1 Wayne A. Sinclair A1 Helen M. Griffiths A1 Ing-Ming Lee YR 1994 UL http://auf.isa-arbor.com/content/20/3/176.abstract AB Mycoplasmalike organisms are obligate parasites of plants and insects. In recent years, advances have been made in detecting and identifying them, distinguishing among those associated with various plant diseases, assigning them to groups based upon homology of DNA base sequences, and determining their roles in decline of trees and shrubs. These advances are reviewed with special reference to ash yellows and elm yellows. Known and probable relationships among MLOs associated with various plant diseases are tabulated.
