Last year I noticed some of my common milkweed (Asclepias syriaca) plants were showing signs of chlorosis – yellowing of the leaves along their veins and some stunted growth. I was horrified by what I found: huge root systems spreading through the bed of milkweeds with great bunches of fasciated shoots. The flowers are excellent for cutting. These phytoplasmic organisms on milkweed are not known to harm caterpillars. The advice is to remove all affected plants and put them in the garbage rather than composting them, to avoid spread of the bacteria. It was also suggested that as the bacteria is species-specific, it is unlikely to affect any caterpillars feeding on the plants. Milkweed yellows phytoplasma MW1 . They cause disease in plants and are spread by insects that feed on the phloem of plants, like leafhoppers. A 1.8 kbp rDNA sequence, amplified from VAC-L phytoplasma in P1/P7-primed PCR, was cloned and se-quenced and the nucleotide sequence deposited in the GenBank database under accession no.

A bacterial disease, milkweed yellows phytoplasma, which is spread by leaf hoppers, seems the most likely cause of the malformations I found. By late August the plants with yellowed leaves had proliferated with no sign of blooms and were also showing considerable malformation which looks to me like a form of fasciation so I decided it was time for them to be removed. Taxonomy - Milkweed yellows phytoplasma (SPECIES) ))) Map to UniProtKB (6) Unreviewed (6) TrEMBL. If left for the leaf hoppers, they’ll quickly spread the bacteria to other plants in the vicinity. Results from phylogenetic analysis based on 16S rRNA gene sequences are consistent with the concept that the BBP phytoplasma represents a distinct new phytoplasma lineage.

Top of page Grapevine yellows (GY) are diseases of Vitis vinifera, characterized by similar symptoms, but differing in aetiology and epidemiology. Phylogenetic analysis based on 16S rRNA gene sequences are consistent with the concept that the ChLL and BBP phytoplasmas represent two distinct phytoplasma lineages.
