First Report of ‘Candidatus Phytoplasma asteris’ Associated with “Witches'-Brooms” on Jointleaf Rush (Juncus articulatus) in Poland

Citation
Jarzembowski et al. (2015). Plant Disease 99 (2)
Names
Ca. Phytoplasma asteris
Abstract
Juncus articulatus L. (Juncaceae) is a species of rush occurring in Eurasia, Canada, and the United States. In 2013, symptoms of “witches'-brooms,” similar to those associated with phytoplasma infection in other plants, were observed on jointleaf rush plants in Lower Silesia (southwest Poland), with some pests feeding on them. Livia junci (Liviinae, Hemiptera) is a small plant-feeding sap-sucking insect that affects monocotyledonous plants. To confirm the presence of phytoplasma in 15 examined

Emergence of ‘Candidatus Liberibacter solanacearum’-Infected Seed Potato in Relation to the Time of Infection

Citation
Rashed et al. (2015). Plant Disease 99 (2)
Names
“Liberibacter solanacearum”
Abstract
Zebra chip (ZC) is a disease of potato, putatively caused by the vectorborne bacterium ‘Candidatus Liberibacter solanacearum’. Although ZC has been a major concern due its significant negative impact on both potato yield and quality, its effect on seed potato sprouting has been the subject of recent evaluations. The present study was conducted to determine whether variation in emergence is affected by the infection duration of ‘Ca. L. solanacearum’-infected seed potato prior to harvest. Further

Effects of Potato-Psyllid-Vectored ‘Candidatus Liberibacter solanacearum’ Infection on Potato Leaf and Stem Physiology

Citation
Wallis et al. (2015). Phytopathology® 105 (2)
Names
“Liberibacter solanacearum”
Abstract
The bacterium ‘Candidatus Liberibacter solanacearum’ is associated with zebra chip disease (ZC), a threat to potato production in North America and New Zealand. It is vectored by potato psyllids. Previous studies observed that ‘Ca. L. solanacearum’ infection causes potato tubers to undergo ZC-symptom-associated shifts in physiology, such as increased levels of amino acids, sugars, and phenolics. However, little is known about how ‘Ca. L. solanacearum’ infections caused by psyllid vector feeding

First Report of Candidatus Phytoplasma solani Associated with Potato Plants in Greece

Citation
Holeva et al. (2014). Plant Disease 98 (12)
Names
Ca. Phytoplasma solani
Abstract
In August 2013, potato plants (Solanum tuberosum) cv. Banba displaying symptoms resembling those caused by Candidatus Phytoplasma solani (potato stolbur phytoplasma) were observed in a 2-ha field in the area of the Peripheral Unit of Drama (northern Greece). The plants were 10 weeks old and their symptoms included reddening and upward rolling of leaflets, reduced size of leaves, shortened internodes, and aerial tuber formation. Incidence of affected plants was estimated to be 40% in the field.

First Report of 16SrII-D Phytoplasma ‘Candidatus Phytoplasma aurantifolia’ Associated with Mung Bean Phyllody in Andhra Pradesh, India

Citation
Ragimekula et al. (2014). Plant Disease 98 (10)
Names
Ca. Phytoplasma aurantifolia
Abstract
Mung bean (Vigna radiata (L.) R. Wilczek) is an important edible legume grown in Asia, particularly in the Indian subcontinent, where it is used for human and animal consumption. In September 2013, 10% of a group of 90 mung bean breeding lines in experimental plots of S. V. Agricultural College, Tirupati, Andhra Pradesh, India, exhibited symptoms typical of a phytoplasma infection, including stunting, extensive proliferation of branches, reduction in leaf size, phyllody, and longitudinal splitt
