A dramatic outbreak of Xylella fastidiosa decimating olive was discovered in 2013 Apulia, Southern Italy. This pathogen is a quarantine bacterium the European Union (EU) and created unprecedented turmoil for local economy posed critical challenges its management. With new emerging threat to susceptible crops EU, efforts were devoted gain basic knowledge on biology, host, environmental interactions (e.g., bacterial strain(s) pathogenicity, hosts, vector(s), fundamental drivers epidemics)...
Discovery of Xylella fastidiosa from olive trees with "Olive quick decline syndrome" in October 2013 on the west coast Salento Peninsula prompted an immediate search for insect vectors bacterium. The dominant xylem-fluid feeding hemipteran collected orchards during a 3-mo survey was meadow spittlebug, Philaenus spumarius (L.) (Hemiptera: Aphrophoridae). Adult P. spumarius, November ground vegetation X. fastidiosa-infected orchards, were 67% (40 out 60) positive by polymerase chain reaction...
In autumn 2013, the presence of Xylella fastidiosa, a xylem-limited Gram-negative bacterium, was detected in olive stands an area Ionian coast Salento peninsula (Apulia, southern Italy), that were severely affected by disease denoted quick decline syndrome (OQDS). Studies carried out for determining involvement this bacterium genesis OQDS and leaf scorching shown number naturally infected plants other than olive. Isolation axenic culture attempted assays its pathogenicity to olive, oleander...
The recent introduction of Xylella fastidiosa in Europe and its involvement the Olive Quick Decline Syndrome (OQDS) Apulia (Salento, Lecce district, South Italy) led us to investigate biology transmission ability meadow spittlebug, Philaenus spumarius, which was recently demonstrated transmit X. periwinkle plants. Four xylem-sap-feeding insect species were found within bordering olive orchards across Salento during a survey carried out from October 2013 December 2014: P. spumarius most...
The recent Xylella fastidiosa subsp. pauca (Xfp) outbreak in olive (Olea europaea) groves southern Italy is causing a destructive disease denoted Olive Quick Decline Syndrome (OQDS). Field observations disclosed that Xfp-infected plants of cv. Leccino show much milder symptoms, than the more widely grown and highly susceptible Ogliarola salentina. To determine whether these field underlie tolerant condition Leccino, which could be exploited for lessening economic impact on local industry,...

Abstract Plant pathogens pose increasing threats to global food security, causing yield losses that exceed 30% in food-deficit regions. Xylella fastidiosa ( Xf ) represents the major transboundary plant pest and one of world’s most damaging terms socioeconomic impact. Spectral screening methods are critical detect non-visual symptoms early infection prevent spread. However, subtle pathogen-induced physiological alterations spectrally detectable entangled with dynamics abiotic stresses. Here,...

Xylella fastidiosa is a plant-pathogenic bacterium recently introduced in Europe that causing decline olive trees the South of Italy. Genetic studies have consistently shown bacterial genotype recovered from infected belongs to sequence type ST53 within subspecies pauca. This genotype, ST53, has also been reported occur Costa Rica. The ancestry was clarified, showing it contains alleles are monophyletic with those subsp. pauca America. To more robustly determine phylogenetic placement X....
We determined the draft genome sequence of Xylella fastidiosa CoDiRO strain, which has been isolated from olive plants in southern Italy (Apulia). It is associated with quick decline syndrome (OQDS) and characterized by extensive scorching desiccation leaves twigs.
Plum pox potyvirus (PPV) isolates may be divided into four groups separated by serological, molecular, and epidemiological differences. Monoclonal antibodies specific for the two major of isolates, represented D M serotypes virus, have been obtained. Polymerase chain reaction (PCR)-based assays allowing direct detection differentiation PPV also developed. We now report on a large-scale comparison these typing approaches. The results obtained show an overall excellent correlation between in...
Olive quick decline syndrome (OQDS) is a devastating disease of olive trees in the Salento region, Italy. This caused by bacterium Xylella fastidiosa, which widespread outbreak area; however, “Leccino” variety olives has proven to be resistant with fewer symptoms and lower bacterial populations than “Ogliarola salentina” variety. We completed an empirical study determine mineral trace element contents (viz; ionome) leaves from infected comparing two varieties, develop hypotheses related...
Abstract Xylella fastidiosa is an important insect‐vectored bacterial plant pathogen with a wide host range, causing significant economic impact in the agricultural and horticultural industries. Once restricted to Americas, severe European outbreaks have been discovered recently Italy, Spain, France, Portugal. The Italian outbreak, detected Puglia 2013, has spread over 100 km, killing millions of olive trees, still expanding. To date, quantified assessment epidemiological parameters useful...
This Scientific report provides an update of the
Xylella fastidiosa subsp. pauca ST53 ( Xfp ) is a pathogenic bacterium causing one of the most severe plant diseases currently threatening olive-growing areas Mediterranean, Olive Quick Decline Syndrome (OQDS). The majority olive cultivars upon infections more or less rapidly develop desiccation phenomena, while few are resistant (e.g. Leccino and FS17), being impacted by infections. present study contributes to elucidating basis resistance phenomenon investigating influence composition...
