Leaf wilting, plant stunting, browning of the vascular system, leaf death and lack of fruit production also occur. [8]
The wilting may only show on one side of the leaf and may recover during cooler periods. [6] The entire system of xylem within the plant allows the bacteria to form titers of up to 10 9 bacteria per gram of plant tissue.
