“…Other phytoplasmas that have been recorded in Rubus spp. include Rubus stunt (16SrV) in the UK, North America and Europe (Lee et al 2000), Aster yellows (16SrI) in the UK (Reeder et al 2010) and Pakistan (Fahmeed et al 2009), a group 16SrIII phytoplasma in the UK (Davies 2000), and Black raspberry witches'-broom phytoplasma (16SrIII-Q) in North America (Davis et al 2001). The relationship between the group 16SrIII phytoplasmas detected in Rubus spp.…”

“…However, phytoplasmas from the groups of X-disease (16SrIII), aster yellows (16SrI), and stolbur (16SrXII) have also been identified in Rubus stunt symptomatic Rubus spp. plants [ 9 – 13 ], and may cause similar symptoms like the ones described above. So far, little is known about the presence and distribution of phytoplasmas in different Rubus species or cultivars, the impact of the respective cultivation system, their geographical spread as well as about the spectrum of putative insect vectors.…”

Rubus stunt is an economically important disease in the production of raspberries, blackberries, and loganberries. A fast, sensitive, and reliable diagnosis of phytoplasmas, the causal agent of the disease, is of prime importance to stop its spread by vegetative propagation and by insect vectors. Therefore, multiplex qPCR assays using TaqMan probes with different kinds of fluorophores in one reaction were developed, allowing the detection of phytoplasmas in general as well as a more specific detection of phytoplasmas belonging to group 16SrV and host DNA (either plant or insect). This assay now provides a practical tool for the screening of motherplants and monitoring the presence and distribution of phytoplasmas in Rubus plants of different geographic origins, cultivars, and cultivation systems, as well as in putative insect vectors like leafhoppers.

“…Usually, Rubus stunt is associated with the presence of ' Candidatus Phytoplasma rubi', which is a phytoplasma belonging to the elm yellows group of phytoplasmas (16SrV). However, phytoplasmas from other groups have also been reported from symptomatic Rubus plants, such as aster yellows phytoplasmas (16SrI‐B) (Borroto Fernández et al, ; Fahmeed, Rosete, Pérez, Boa, & Lucas, ; Reeder, Kelly, & Arocha, ), X‐disease phytoplasmas (16SrIII) (Davies, ; Davis, Dally, & Converse, ) and stolbur phytoplasmas (16SrXII‐A) (Borroto Fernández et al, ). More recently, a new phytoplasma was identified in blackberry plants showing witches' broom symptoms in Portugal that was named blackPort phytoplasma (Fránová et al, ).…”

Phytoplasmas are cell wall‐less phytopathogenic bacteria which are associated with a disease in Rubus species known as Rubus stunt. Symptoms range from stunting, witches’ broom, small leaves, short internodes, enlarged sepals, phyllody and flower proliferation to fruit malformations. Phytoplasmas can be spread by vegetative propagation and by phloem‐feeding insect vectors. However, little is known about the spectrum and distribution of putative Rubus stunt insect vectors. In this study, a screening of putative insect vectors of Rubus stunt in raspberry plantations in southern and northern Germany was carried out during two successive years (2014 and 2015) with multiple sampling dates throughout the growing seasons. A total of 2,891 hemipteran insects were sorted, identified to family, genus or species level when possible, and a subset of 319 DNA samples containing a sum of 932 selected individuals representing all identified species, sampling locations and sampling dates were tested for phytoplasma DNA using qPCR. Altogether, eight DNA samples were positive for phytoplasma DNA, among them species from the genera Euscelidius, Macrosteles, Euscelis, Anaceratagalliaand Psammotettix. These data will form the basis for choosing and timing appropriate control measures against Rubus stunt and also for potential insect vector transmission experiments.
