useful microorganism is a Phytoplasma that infects the
phloem of poinsettias. Phloem is like a blood vessel for plants.
It takes the nutrients and water from the roots to the
leaves. Poinsettias that are fuller and more highly branched
are more useful.
To get these fuller plants, we have to propagate them by
grafting branches of Phytoplasma -infected poinsettias onto
young poinsettias.
The Phytoplasmas are infected in the wild by insects called
leaf hoppers. When the leaf hoppers bite into the plant they
leave behind the Phytoplasma. When infected, the poinsettia
is shorter and has many more branches.
