“…prevention of pathogen movement) or susceptibility (i.e. by reduction of water movement) continues to be a matter of debate (Cantu et al ., ). Numerous observations have confirmed that extensive tylose formation in compatible X. fastidiosa –host interactions has an impact on plant water transport, which, in turn, worsens the symptoms of the disease (Choi et al ., ; Machado and Tyree, ; Perez‐Donoso et al ., ; Sun et al ., ).…”

“…Moreover, stacking the resistance genes (or transgenes) mentioned above could also be accomplished by crossing plants of the same rootstock variety. Therefore, if transgenic rootstock strategies for PD defence prove to be effective, it is likely that only a few particular rootstock genotypes would be needed for deployment with numerous V. vinifera grape scion varieties (Cantu et al ., ).…”

Most X. fastidiosa-related diseases appear as marginal leaf necrosis and scorching of the leaves. In the case of PD, X. fastidiosa can also cause desiccation of berries (termed 'raisining'), irregular periderm development and abnormal abscission of petioles. In olive trees affected with OQDS, leaves exhibit marginal necrosis and defoliation, and overall tree decline occurs. Plants with ALS and OLS also exhibit the characteristic leaf scorch symptoms. Not all X. fastidiosa-related diseases exhibit the typical leaf scorch symptoms. These include CVC and Phony Peach disease, amongst others. In the case of CVC, symptoms include foliar wilt and interveinal chlorosis on the upper surfaces of the leaves (similar to zinc deficiency), which correspond to necrotic, gum-like regions on the undersides of the leaves. Additional symptoms of CVC include defoliation, dieback and hardening of fruits. Plants infected with Phony Peach disease exhibit a denser, more compact canopy (as a result of shortened internodes, darker green leaves and delayed leaf senescence), premature bloom and reduced fruit size. Some occlusions occur in the xylem vessels, but there are no foliar wilting, chlorosis or necrosis symptoms .

Plant diseases are responsible for major crop losses and postharvest spoilage; though losses are difficult to calculate, educated estimates suggest they are responsible for 20% to 40% of losses from plough to plate for major crops (Oerke, 2006;Savary et al., 2019). Hypothetically, with current estimated population growth, we could solve the challenge of feeding the world by 2050 were we able to control all disease (Collinge et al., 2010). Plant disease can be managed primarily by farmer skill, pesticides, disease resistance, and biological control, in roughly that order of importance. Disease resistance is effective when it works because no specific input is required by the grower after sowing or planting. However, despite major effort by plant pathologists and breeders over a century, no effective disease-resistant cultivars are available for many diseases, and, for many important diseases, the pathogen overcomes natural
