Experimental infection of Alstroemeria seedlings with naturally infected lily ‘Casablanca’ with stunting and flower bud deficiency phytoplasma resulted 3–4 weeks after top grafting in chlorotic and/or necrotic stripes, whitening of the leaves, shoot necrosis and die back. Flower discoloration or malformation were not observed. Attempts to transmit phytoplasma from naturally infected lily and experimentally infected Alstroemeria to Catharanthus roseus by top grafting resulted in stunted growth, dull yellowing and malformation of the leaves in 4–6 weeks. Some plants were temporary entirely vegetative and did not produce flowers. The periwinkle plants that were bridged by Cuscuta odorata from the diseased lilies and Alstroemerias showed similar symptoms as top-grafted ones. With the universal primer pairs rU3/fU5 specific PCR product with expected length ∼900 was amplified from samples collected from lilies with severe symptoms and top grafted test plants. All PCR products used for RFLP analysis after digestion with Alu I showed the same restriction profiles. Position of three obtained bands corresponded to the lengths of the DNA fragments of American aster yellows (AAY) phytoplasma group.
