Abstract

Chinese chestnut trees ( Castanea mollissima BL.) planted in a suburb of Beijing, China developed symptoms including yellowing, leaf crinkling, little leaf, shortened internodes, and empty burrs. Transmission electron microscopy revealed presence of phytoplasma cells in phloem sieve elements of the symptomatic chestnut trees. Molecular cloning and sequence analysis of PCR-amplified near-full length 16S rRNA gene indicated that the phytoplasma associated with the Chinese chestnut yellow crinkle disease is closely related to Japanese chestnut witches'-broom phytoplasma. This is the first report of a phytoplasmal disease in Chinese chestnut trees. [ABSTRACT FROM AUTHOR]
