The article reflects on a report of a phytoplasma associated with Christmas cactus witches' broom. The report states that symptom of witches' broom and stunted growth was found in a pot containing a Christmas cactus with cladoded showing conspicuous malformed branches at the Agricultural University, Kunming. Samples from the plant showing signs of witches' broom and symptomless plants were analyzed for the presence of phytoplasmas using 16S rDNA PCR assays. The analysis of the 16S rDNA sequence delineated the Christmas cactus witches's broom phytoplasma as a Peanut witches'-broom group member, which closely related to the broad bean phyllody phytoplasma. |
