Right you are as usual, lefteh. From the Texas Tech Plant Molecular Biology Lab: “Agrobacterium tumefaciens is a plant pathogen that causes a disease in dicotyledonous (broad-leafed) plants called crown gall. A crown gall is a tumor that usually forms on the stem of plants that consists of rapidly dividing cells. The crown gall is essentially a plant cancer. These galls do not kill the plant directly but they tap resources from the plant and can sometimes grow large enough to block the vascular system of the stem.”
Right? lefteh? Perhaps you should change that to righteh, although it does not have the same ring to it.
