“…Phytoplasmas, previously called mycoplasma-like organisms (MLO), are unculturable, phloem-limited and insect-transmitted plant pathogens, and have been associated with diseases in hundreds of plant species, including many important food crops, ornamentals, Serious epidemics of purple top disease of potato, caused by phytoplasma infections, have recently occurred in North America (Leyva-López et al 2002;Khadhair et al 2003;Lee et al 2004;Munyaneza 2005;Munyaneza et al 2006;RubioCovarrubias et al 2006;Secor et al 2006;Olivier et al 2009;Munyaneza et al 2008b;2010a;Santos-Cervantes et al 2010), Central and South America (Secor and Rivera-Varas 2004;Jones et al 2004), central and eastern Europe (Linhartova et al 2006;Paltrinieri and Bertaccini 2007;Bogoutdinov et al 2008;Girsova et al 2008;Fialova et al 2009), and New Zealand ). Countries severely affected by phytoplasma diseases of potato include Russia, Romania, Mexico, Guatemala, and the United States.…”

In recent years, emerging phytoplasma diseases of potato (Solanum tuberosum L.) have increasingly become important in central and eastern Europe. Accurate identification of phytoplasmas and their insect vectors is essential to developing effective management strategies for diseases caused by these plant pathogens. Potato phytoplasma diseases in Europe were for a long time diagnosed only on the basis of visual symptoms. However, this approach is not very reliable and the use of modern molecular techniques such as polymerase chain reaction (PCR) is required in order to accurately determine the etiology of these phytoplasma diseases. A survey and identification of phytoplasmas associated with potato crops in Romania and southern Russia were conducted based on modern molecular techniques. Symptomatic potato plants were collected from several fields and tested for phytoplasmas by PCR.Also, selected crops and weeds in the vicinity of these potato fields were sampled and tested for phytoplasmas. Stolbur ("Candidatus Phytoplasma solani"; 16SrXII-A) was the only phytoplasma detected in potato and adjacent crops, including tomato (Solanum lycopersicum), pepper (Capsicum annuum), eggplant (Solanum melongena), and beet (Beta vulgaris). This phytoplasma was also detected in weeds, particularly Convolvulus arvensis, Cuscuta sp., and Euphorbia falcata. Genotyping of obtained stolbur isolates on tuf genes revealed that they all had the same RFLP profile corresponding to the tuf-type 'b' (VK Type II). Stolbur-affected potato plants produced a large number of spongy tubers that resulted in commercially unacceptable potato chips upon processing.

Potato purple top disease (PPTD), the most important phytoplasma disease of potato, is caused by different phytoplasmas such as those related to ‘ Candidatus Phytoplasma astris’ (Jones et al. 2005), clover proliferation (16SrVI) (Hiruki and Wang 2004), peanut witches’‐broom (16SrII) and American potato purple top wilt (16SrXVIII) (Lee et al.…”

Potato plants with symptoms suggestive of potato purple top disease (PPTD) occurred in the central, western and north-western regions of Iran. Polymerase chain reaction (PCR) and nested PCR assays were performed using phytoplasma universal primer pair P1 ⁄ P7 followed by primer pairs R16F2n ⁄ R16R2 and fU5 ⁄ rU3 for phytoplasma detection. Using primer pairs R16F2n ⁄ R16R2 and fU5 ⁄ rU3 in nested PCR, the expected fragments were amplified from 53% of symptomatic potatoes. Restriction fragment length polymorphism (RFLP) analysis using AluI, CfoI, EcoRI, KpnI, HindIII, MseI, RsaI and TaqI restriction enzymes confirmed that different phytoplasma isolates caused PPTD in several Iranian potato-growing areas. Sequences analysis of partial 16S rRNA gene amplified by nested PCR indicated that ÔCandidatus Phytoplasma solaniÕ, ÔCa. Phytoplasma astrisÕ and ÔCa. Phytoplasma trifoliiÕ are prevalent in potato plants showing PPTD symptoms in the production areas of central, western and north-western regions of Iran, although ÔCa. Phytoplasma solaniÕ is more prevalent than other phytoplasmas. This is the first report of phytoplasmas related to ÔCa. Phytoplasma astrisÕ, ÔCa. Phytoplasma solaniÕ and ÔCa. Phytoplasma trifoliiÕ causing PPTD in Iran.

“…Phytoplasmas are infrequently passed to daughter tubers, although some aster yellows strains prevent infected tubers from sprouting or else produce elongated hair sprouts that, in turn, produce weak plants that do not survive (Conners 1967, Salazar and Javasinghe 2001, Leyva-López et al 2002, Jones et al 2004 and which produce few marketable tubers. The bases of young leaflets turn purplish, reddish, or yellowish.…”
