A fall visit, October, to a plant displaying signs of Milkweed Yellows. I return to the same plant the following spring, May, to see how the phytoplasma is displaying in the plant.
Phytoplasmas are cellular bacterias that have an obligate relationship to plant cells. Milkweed Yellows Phytoplasma interacts with milkweed plant tissue on the cellular level. MW1, as it is abbreviated, is an obligate intracellular parasite. Signs of MW1 include the following four things.
1 Chlorosis of the leaf
2 Irregular vascular development including anthocyanin
3 Leaf deformation, especially at the leaf edges
4 Flowers expressing leaf growth in place of petals "Witches Broom"
