Subject: New pathway discovered for the transmission of Xylella fastidiosa
Date posted: August 01, 2003

Xylella fastidiosa, a bacterium thought to be spread only by insect vectors such as glassy winged sharpshooters or contaminated budwood, is now known to infect and colonize orange fruit tissues and seeds and be transmissible from the seeds to seedlings. This is the first report of X. fastidiosa transmission through seeds. Various strains of Xylella cause diseases in economically important crops such as citrus variegated chlorosis in Brazilian oranges, coffee leaf scorch in South America and Pierce's disease of grapevines in North and Central America.
