“…Similarly, constitutive expression of OsGH3.1 (in IIB) alters auxin homeostasis and enhances resistance to the fungal pathogen Magnaporthe grisea (Domingo et al 2009). Furthermore, the IIA genes PtGH3.1 and PtGH3.2 were induced in EMF-colonized tree roots (Felten et al 2009) and VvGH3.2 (probeset: 1610880_s_at) expression was elevated in response to infection with Bois Noir phytoplasma (Albertazzi et al 2009). …”

GH3 amino acid conjugases have been identified in many plant and bacterial species. The evolution of GH3 genes in plant species is explored using the sequenced rosids Arabidopsis, papaya, poplar, and grape. Analysis of the sequenced non-rosid eudicots monkey flower and columbine, the monocots maize and rice, as well as spikemoss and moss is included to provide further insight into the origin of GH3 clades. Comparison of co-linear genes in regions surrounding GH3 genes between species helps reconstruct the evolutionary history of the family. Combining analysis of synteny with phylogenetics, gene expression and functional data redefines the Group III GH3 genes, of which AtGH3.12/PBS3, a regulator of stress-induced salicylic acid metabolism and plant defense, is a member. Contrary to previous reports that restrict PBS3 to Arabidopsis and its close relatives, PBS3 syntelogs are identified in poplar, grape, columbine, maize and rice suggesting descent from a common ancestral chromosome dating to before the eudicot/monocot split. In addition, the clade containing PBS3 has undergone a unique expansion in Arabidopsis, with expression patterns for these genes consistent with specialized and evolving stress-responsive functions.

“…Recent studies on BN have shown several transcriptional and metabolic changes in the host plant. Specifically, the genes involved in primary and secondary metabolism are changed in response to infection; several photosynthetic genes are largely down-regulated in infected plant tissues, whereas the genes involved in carbohydrate metabolism, genes associated with the flavonoid synthesis pathway, some genes encoding pathogenesis-related (PR) proteins and genes associated with reactive oxygen species production are significantly induced (Hren et al 2009a, b;Albertazzi et al 2009;Landi and Romanazzi 2011;Santi et al 2013;Covington Dunn et al 2016). Several metabolites associated with activities of the enzyme products of these genes have also been demonstrated as increased in infected plants (Prezelj et al 2016b).…”

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

et al. 2017

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.

“…Considerable and tissue specific modulations were found for genes related to the cell wall metabolism, which are most likely correlated to the anatomical aberrations found on the plates of sieve tubes in infected plants [2,6,10]. Jagoueix-Eveillard et al [5] reported a down-regulation of a putative sterol-C-methyltransferase in periwinkle after infection with stolbur phytoplasma and associated this gene repression with leaf yellowing and stunting.…”

“…This inhibition may also have an impact on the carbohydrate metabolism, particularly on the accumulation of soluble carbohydrates and starch, as observed in source leaves of plants infected by phytoplasmas [11e14]. Albertazzi et al [6] and Hren et al [8] have recently found that specific genes such as vacuolar invertase and sucrose synthase were up-regulated in phytoplasma-infected grapevine leaves, which may be linked to the negative interferences with sucrose metabolism [11,12]. Beside the transcriptional changes strictly related to the primary and secondary metabolism, other major alterations were found in the host tissues and included the activation of defence genes such as the heat shock protein 70 (Hsp70) and genes coding for pathogenesis-related (PR) proteins, which are downstream components of systemic acquired resistance in plants [6,8].…”
