Wheat blue dwarf(WBD) is an important d isease ofwinterwheat d issem inated byPsammotettix Shaanxi and Northwest area.Phytoplasma was observed in the phloem sieve elements of wheat leaf tis-sues and hind intestine ofP.striatusL.under the electron m icroscope.Using primers(Rm16F2 /Rm16R1) for phytoplasma 16S rDNA,a 1.4 kb DNA fragmentwas amplified by polymerase chain reaction in DNA samples ex-tracted from infected wheats but not in those extracted from healthy plants.Homology ana… Expand
16S rDNA sequence analysis of witches’ broom phytoplasma isolates from Chinese jujube in North China
Virtual RFLP and single-nucleotide polymorphism (SNP) analysis of 16S rDNA revealed that JWB isolates have a relatively low level of genetic diversity and that their SNP sites exhibit a strong bias toward A/G variation when compared with other phytoplasmas. Expand
The agent associated with blue dwarf disease in wheat represents a new phytoplasma taxon, 'Candidatus Phytoplasma tritici'.
Wheat blue dwarf (WBD) is one of the most economically damaging cereal crop diseases in northwestern PR China. The agent associated with the WBD disease is a phytoplasma affiliated with the asterExpand
