Phyllody disease is a threat to sesame production in Kerman province, southeastern Iran. RFLP analysis of PCR products of phytoplasma-specific 16S rRNA gene (1.8 kb) and phylogenetic analyses of 16S-23S rDNA spacer region (SR) sequence indicated that the predominant agent associated with sesame phyllody in Kerman province is a phytoplasma with 100% similarity with eggplant big bud, and peanut witches’-broom phytoplasmas, members of “CandidatusPhytoplasma aurantifolia” from Iran and China, respectively. Among the samples tested, only one strain (SPhSr1), had a unique RFLP profile and its SR was 100% similar in nucleotide sequence with the phytoplasma carried byOrosius albicinctusandHelianthus annuswitches’-broom phytoplasma from Iran, members of “Ca.Phytoplasma trifolii”. Virtual RFLP patterns of SPhJ2 (representative of the predominant PCR-RFLP profiles) SR sequence were identical to those of peanut witches’-broom phytoplasma (16SrII-A, JX871467). However, SPhSr1 SR sequence patterns resemble (99.7%) those of vinca virescence phytoplasma (16SrVI-A, AY500817). [ABSTRACT FROM PUBLISHER] |
