摘要：

An extensive survey was performed from 2002 to 2006 to detect and identify phytoplasmas associated with Chilean grapevines. Nested polymerase chain reaction assays using phytoplasma universal primer pairs P1/P7 and R16F2n/R2 detected phytoplasmas in 34 out of the 94 samples tested (36%). Restriction fragment length polymorphism (RFLP) analyses. cloning, and sequencing allowed identification of phytoplasmas belonging to ribosomal subgroups 16SrI-B 16SrI-C, 16SrVII-A, and l6SrXII-A. The 16SrVII-A phytoplasma represents a new finding ill grapevines moreover, variability of the RFLP profile was observed in some of the 16SrXII-A phytoplasmas, indicating possible new ribosomal subgroups. Mixed phytoplasma infections and infections of phytoplasmas together with one or more viruses also occurred.
