The most common phytoplasma effects on plants resemble the common “yellows” and can affect over 200 plant species, both monocots and dicots. Googling suggested that milkweeds generally suffer from few pests and diseases although they are less studied than commercial plants species. 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. I was horrified by what I found: huge root systems spreading through the bed of milkweeds with great bunches of fasciated shoots.

Milkweed yellows phytoplasma is a more serious issue identified by malformed, yellowish growth and branch dieback. Phylogenetic analysis (using MEGA v4.0) of the 16S rDNA sequence (Fig. 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. He said it was spread by leafhoppers from plant to plant. I shall have to watch the milkweed patch more carefully as the root systems of the malformed plants were very extensive and I’m sure I’ve missed some.
