crown gall Agrobacterium tumefaciens more than 100 genera of woody and herbaceous plants initially a small enlargement of stems or roots usually at or near the soil line, increasing in size, becoming wrinkled, and turning brown to black the conversion of a normal cell to one that produces excessive cell multiplication is caused by a plasmid (a small circular piece of DNA) carried by the pathogenic bacterium
aster yellows Mycoplasma-like organism (MLO) many vegetables, ornamentals, and weeds chlorosis; dwarfing malformations greatest losses suffered by carrots; transmission by leafhoppers
citrus stubborn disease Spiroplasma citri (MLO) citrus and stone fruits and vegetables chlorosis, yellowing of leaves, shortened internodes, wilting first MLO pathogen of plant disease cultured
