Phytoplasma presence in carrot seedlings

[摘要] Phytoplasmas are cell wall lacking bacteria, insect transmitted, and worldwide infecting carrots with severe epidemics. Molecular tests on up to 4-month-old carrot seedlings from phytoplasma-positive seed batches, carried out under insect proof conditions, indicated that in the early stages of the plant development, the phytoplasma-infected and not water-stressed plants are asymptomatic. The phytoplasma seed transmission could represent a dangerous source of infection.
