Soybean bud proliferation (Sbp) disease is associated with a phytoplasma of the 16SrVI-A subgroup. Because of the widespread occurrence of this disease, the possibility of its seed transmission was studied. Seeds collected from Sbp infected, or symptomatic plants were examined and compared with those collected from asymptomatic soybean plants. The results showed that none of the plants grown from seeds collected from asymptomatic plants were positive for the presence of phytoplasmas. Five months after germination, soybean plants grown from the seeds collected from symptomatic plants showed typical symptoms of Sbp disease under greenhouse conditions and also tested positive for phytoplasmas in nested PCR. Sbp is a new phytoplasma disease that could be transmitted through seeds in Iran.
