Abstract:
Phytoplasmas were detected in S ophora japonica cv. golden and R obinia pseudoacacia with diseased branches of witches'‐broom collected in H aidian district, B eijing, C hina. Phytoplasma cells were observed in phloem sieve elements of symptomatic S . japonica cv. golden by transmission electron microscopy. The presence of phytoplasmas was further confirmed by sequence determination of partial gene sequences of 16S rDNA , rp (ribosomal protein) and secY . Phylogenetic trees and virtual restriction fragment length polymorphism ( RFLP ) analyses indicated that the phytoplasmas causing S . japonica cv. golden witches'‐broom ( SJGWB ) and R . pseudoacacia witches'‐broom ( RPWB ) belong to the 16SrV (elm yellows) group, and they are most closely related to subgroup 16SrV‐B, rpV‐C and secYV‐C jujube witches'‐broom ( JWB ) phytoplasma. Comparative analyses indicated that the phytoplasma of RPWB was closer to the JWB and that R . pseudoacacia might serve as an alternative host plant of JWB phytoplasma.
