“…P. solani' infection of vegetables in the world. This pathogen was previously reported to infect tomatoes naturally as well as at least 100 plant species from 40 families (Yaman 1971;Reckhaus et al, 1988;Özdemir et al, 2009).…”

The phytoplasma associated diseases are an emerging threat to fruit and vegetable crops leading severe yield losses worldwide. Pear (Pyrus communis L.) trees, with symptoms of severe reddening, dwarfing and shoot proliferation were observed in pear orchards of Malatya province of Turkey. Tomato (Solanum lycopersicum L.) plants grown nearby the symptomatic pear orchard displaying leaf rolling, severe flower sterility and purple leaves were observed at the same agroecosystem. To verify the presence and diversity of phytoplasmas, symptomatic pears and tomatoes were sampled and weeds nearby the symptomatic plants were collected. Total plant DNA was purified from midrib of collected leaves using a commercial kit. The DNA samples were analyzed by nested polymerase chain reaction (PCR) using universal primer pairs to amplify 16S rDNA fragments. The phytoplasmas detected in collected samples were differed according to the host. Here we detected and characterized ‘Candidatus Phytoplasma pyri’ belonging to apple proliferation group (subgroup 16SrX-C) from a pear tree, ‘Candidatus Phytoplasma trifolii’ belonging to clover proliferation group (subgroup 16SrVI-A) from a weed (Amaranthus retroflexus) and ‘Candidatus Phytoplasma solani’ belonging to the stolbur phytoplasma group (subgroup 16SrXII-A) from a tomato plant. Direct sequencing of PCR products verified the phytoplasmal nature of the infections. The occurrence of ‘Ca. P. trifolii’ on A. retroflexus is the first report for the world. The irregular presence of the phytoplasmas in fruit and vegetable crops and weeds indicates continuous spread of the phytoplasmas threatening the new crops and new horizons.

Two symptomatic tomato plants exhibiting dwarfing, twisting of shoots and leaves, virescence and phyllody of flowers were collected, respectively, from a greenhouse (Soly07fi) or the field (Soly06gh) in the western region of Poland. Direct and nested polymerase chain reactions (PCR) were performed using universal phytoplasma primers P1 ⁄ P7 and R16F2n ⁄ R16R2. Restriction fragment length polymorphism (RFLP) analysis of the PCR products showed that the RFLP profiles of both tested phytoplasma isolates are the same and that they belong to the phytoplasma 16S rRNA I-C subgroup. The homology between the two strains was 99%. Phylogenetic analysis of the 16S rRNA gene sequences of the phytoplasma isolates and other phytoplasma sequences available in the GenBank database indicated that the Polish phytoplasma isolates are most closely related to the phytoplasma 16S rRNA I-C subgroup.

Parasitic plants represent a peculiar group of semi- or fully heterotrophic plants, possessing the ability to extract water, minerals, and organic compounds from other plants. All parasitic plants, either root or stem, hemi- or holoparasitic, establish a vascular connection with their host plants through a highly specialized organ called haustoria. Apart from being the organ responsible for nutrient extraction, the haustorial connection is also a highway for various macromolecules, including DNA, proteins, and, apparently, phytopathogens. At least some parasitic plants are considered significant agricultural pests, contributing to enormous yield losses worldwide. Their negative effect is mainly direct, by the exhaustion of host plant fitness and decreasing growth and seed/fruit formation. However, they may pose an additional threat to agriculture by promoting the trans-species dispersion of various pathogens. The current review aims to summarize the available information and to raise awareness of this less-explored problem. We further explore the suitability of certain phytopathogens to serve as specific and efficient methods of control of parasitic plants, as well as methods for control of the phytopathogens.
