The genetic diversity of aster yellows phytoplasmas in grapevine collected in two locations in South Africa (Vredendal and Robertson) was investigated by the use of multilocus analysis of gene sequences amplified by polymerase chain reaction. Based on results from restriction fragment length polymorphism profiling and nucleotide sequence alignments of 16S rRNA, rp, amp, groEL and secY genes in comparison with aster yellows strains from Italy and reference aster yellows strains, four lineages have been detected in samples from South Africa.

Abstract
The genetic diversity of aster yellows phytoplasmas in grapevine collected in two locations in South Africa (Vredendal and Robertson) was investigated by the use of multilocus analysis of gene sequences amplified by polymerase chain reaction. Based on results from restriction fragment length polymorphism profiling and nucleotide sequence alignments of 16S rRNA, rp, amp, groEL and secY genes in comparison with aster yellows strains from Italy and reference aster yellows strains, four lineages have been detected in samples from South Africa.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
