“…Members of group 16SrXII have been detected in a large number of plants worldwide, with a high incidence in grapevines (Davis et al, 1997;Cheng et al, 2012;Quaglino et al, 2013). With five candidate species of 'Ca.…”

“…In Europe, 'Candidatus Phytoplasma solani' from the stolbur group 16 SrXII-A (Quaglino et al 2013), which causes bois noir (BN) disease, is the most widespread and may lead to up to 50% loss of grape clusters (Starý et al 2013). BN is usually endemic in the Euro-Mediterranean area, and its spread occurs via a complicated disease cycle which includes insect vectors and multiple herbaceous plants as phytoplasma reservoirs (Belli et al 2010;Cvrković et al 2014).…”

Statistical modeling of long-term grapevine response to ‘Candidatus Phytoplasma solani’ infection in the field

Bois noir (BN) is the most widespread European grapevine yellows disease caused by 'Candidatus Phytoplasma solani'. Although our knowledge of the mechanisms of interactions of this pathogenic bacteria with host is largely unknown, the plant-pathogen system of BN is commonly used as a model system for studying grapevine yellows diseases. We applied here a conceptual model of general plant pathology -a disease triangle for describing interactions among the host plant, the pathogen and the environment. We generated a proofof-concept statistical model for disease triangle using original experimental data and different statistical and data mining approaches for a selected system of 'Ca. P. solani' infection of cv. 'Chardonnay' grapevine plants. We monitored individual plants from a single vineyard over a period of six years. Phytoplasma content, the expression of 21 selected grapevine genes and environmental conditions were recorded and related to disease severity. Our model predicts that in described conditions BN is a function of the expression of grapevine gene VvDMR6, summer rainfall and abundance of 'Ca. P. solani'. The greatest impact among elements of the disease triangle is attributed to the pathogen, and is independent of the pathogen titer. We showed that this first de facto representation of the disease triangle is useful for showing disease dynamics over several years and could be applied to other plant-pathogen systems. The overall results of this study will contribute to understanding of 'Ca. P. solani' biology and its interactions with grapevine host.

“…'Candidatus Phytoplasma solani' is from the stolbur group/ 16SrXII-A of phytoplasmas (Quaglino et al 2013), and is associated with Bois noir disease (i.e., Bois noir phytoplasma; BNp). In Europe, Bois noir disease is widespread.…”

Rapid loop-mediated isothermal amplification assays for grapevine yellows phytoplasmas on crude leaf-vein homogenate has the same performance as qPCR

A fluorescence-based real-time loop-mediated isothermal amplification (LAMP) assay for 'Candidatus Phytoplasama solani' (Bois noir phytoplasma; BNp) detection was developed and optimised for rapid laboratory and on-site BNp detection. This assay is highly specific, rapid and as sensitive as qPCR. It was validated according to European and Mediterranean Plant Protection Organisation recommendations. In addition, 286 grapevine leaf samples from the 2015 growing season were tested with this new real-time LAMP assay and an assay previously developed for detection of Flavescence dorée phytoplasma (FDp). These LAMP assays for detection of both BNp and FDp used without any DNA extraction step, which is a required step for qPCR analysis, were comparably effective to qPCR, and positive results were obtained in less than 35 min.
