A Conjugative 38 kB Plasmid Is Present in Multiple Subspecies of Xylella fastidiosa

A similar to 38kB plasmid (pXF-RIV5) was present in the Riv5 strain of Xylella fastidiosa subsp. multiplex isolated from ornamental plum in southern California. The complete nucleotide sequence of ...

*Analysis of potential distribution of Xylella fastidiosa subsp. multiplex ST-6 AND Philaenus spumarius IN THE SOUTH OF THE IBERIAN PENINSULA. THE ECOLOGICAL MODEL OF NICHE MAXENT

The ecological model of niche MaxEnt has been used to know the potential distribution of Xylella fastidiosa subsp. multiplex and the associated vector Philaenus spumarius in the south of the Iber...

A New Resource for Research and Risk Analysis: The Updated European Food Safety Authority Database of Xylella spp. Host Plant Species

Following a series of requests for scientific advice from the European Commission starting in 2013, the European Food Safety Authority (EFSA) conducted a pest risk assessment and created a comprehe...

Categorisation of plants for planting, excluding seeds, according to the risk of introduction of Xylella lfastidiosa

Following a request from the European Commission, EFSA was asked to provide urgent technical assistance in the field of plant health as regards the list of host plants of Xylella fastidiosa reporte...

Comparative genomics of Clavibacter michiganensis subspecies, pathogens of important agricultural crops

Subspecies of Clavibacter michiganensis are important phytobacterial pathogens causing devastating diseases in several agricultural crops. The genome organizations of these pathogens are poorly und...

Descriptions of eight new Acrogonia species from the Amazon region, including peculiar features of the female genitalia (Hemiptera: Cicadellidae: Cicadellinae: Proconiini)

Eight new species of the agriculturally important sharpshooter genus Acrogonia Stal, 1869 are described and illustrated from Brazil (one of them also recorded from Peru): A. amazonensis sp. nov. (s...

Development of A Nested-MultiLocus Sequence Typing Approach for A Highly Sensitive and Specific Identification of Xylella fastidiosa Subspecies Directly from Plant Samples

Identification of sequence types (ST) of Xylella fastidiosa based on direct MultiLocus Sequence Typing (MLST) of plant DNA samples is partly efficient. In order to improve the sensitivity of X. f...

Fecundity and success of progeny produced by Homalodisca coagulata (Hemiptera : Cicadellidae) on single host species

This study tested the hypothesis that Homalodisca coagulata (Say) (Hemiptera: Cicadellidae) confined to a single host cannot successfully produce progeny and survive to complete a generation. We fo...

Feeding and Development of the Glassy-Winged Sharpshooter, Homalodisca vitripennis, on Australian Native Plant Species and Implications for Australian Biosecurity

In any insect invasion the presence or absence of suitable food and oviposition hosts in the invaded range is a key factor determining establishment success. The glassy-winged sharpshooter, Homalod...

Formation of Stylet Sheaths in aere (in air) from Eight Species of Phytophagous Hemipterans from Six Families (Suborders: Auchenorrhyncha and Sternorrhyncha)

Stylet sheath formation is a common feature among phytophagous hemipterans. These sheaths are considered essential to promote a successful feeding event. Stylet sheath compositions are largely unkn...

Genetic analysis of a novel Xylella fastidiosa subspecies found in the Southwestern United States

Xylella fastidiosa, the causal agent of several scorch diseases, is associated with leaf scorch symptoms in Chitalpa tashkentensis, a common ornamental landscape plant used throughout the southwest...

Genetic differences between blight-causing Erwinia species with differing host specificities, identified by suppression subtractive hybridization

PCR-based subtractive hybridization was used to isolate sequences from Erwinia amylovora strain Ea110, which is pathogenic on apples and pears, that were not present in three closely related strain...
