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.
