Detection of 16SrVI and 16SrIX phytoplasma groups in pot marigold and tickseed plants in northeastern Iran.

Pot marigold and tickseed are ornamental plants with many medicinal and cosmetic uses and for landscape, respectively. During a survey in 2018, phyllody symptoms were observed in high percentages in these plants in some regions of the Razavi Khorasan province (northeastern Iran). Total DNA was extracted from symptomatic and asymptomatic plants and polymerase chain reaction was carried on using universal phytoplasma primer pairs P1/P7 and nested primer pairs R16F2n/R16R2.

Diversity of beet curly top Iran virus isolated from different hosts in Iran.
