A multigene phylogenetic study of clonal diversity and divergence in North American strains of the plant pathogen Xylella fastidiosa

Xylella fastidiosa is a pathogen that causes leaf scorch and related diseases in over 100 plant species, including Pierce's disease in grapevines (PD), phony peach disease (PP), plum leaf scald (PL...

An Experimental Test of the Host-Plant Range of Nonrecombinant Strains of North American Xylella fastidiosa subsp. multiplex

Nonrecombinant strains of Xylella fastidiosa subsp. multiplex (those lacking evidence of significant intersubspecific homologous recombination) infect the xylem of a wide range of native and nonnat...

First Report of Bacterial Leaf Scorch Disease of American Elm Caused by Xylella fastidiosa in Georgia, USA

The American elm (Ulmus americana) is a highly desirable deciduous shade tree with moderately dense foliage and a symmetrical broad or upright vase-shaped crown. This plant is susceptible to variou...

Genetic Control of Growth Traits and Inheritance of Resistance to Bacterial Leaf Scorch in American Sycamore

Open-pollinated progeny tests of American sycamore (Platanus occidentalis L.), which included 55 open-pollinated families selected from several prior Westvaco progeny tests and seed orchards and si...

High-Quality Draft Genome Sequence Resources of Eight Xylella fastidiosa Strains Isolated from Citrus, Coffee, Plum, and Hibiscus in South America.

Xylella fastidiosa subsp. pauca, once confined to South America and infecting mainly citrus and coffee plants, has been found to be associated with other hosts and in other geographic regions. We...

NEW RECORDS ON THE GEOGRAPHICAL DISTRIBUTION OF SOUTH AMERICAN SHARPSHOOTERS (CICADELLIDAE: CICADELLINAE: PROCONIINI) AND THEIR POTENTIAL AS VECTORS OF XYLELLA FASTIDIOSA

The Proconiini comprises 422 species distributed in the continental Americas, the highest biodiversity is found in the Neotropical Region (Wilson et al. 2009). Members of the tribe Proconiini have ...

PATHOGENICITY OF XYLELLA-FASTIDIOSA IN AMERICAN ELM AND FAILURE OF RECIPROCAL TRANSMISSION BETWEEN STRAINS FROM ELM AND SYCAMORE

Pathogenicity of Xylella fastidiosa was demonstrated in American elm seedlings. Ten 4-mo-old seedlings were stem-inoculated with a pure culture of X. fastidiosa obtained from a naturally infected e...

Specific Detection and Identification of American Mulberry-Infecting and Italian Olive-Associated Strains of Xylella fastidiosa by Polymerase Chain Reaction

Xylella fastidiosa causes bacterial leaf scorch in many landscape trees including elm, oak, sycamore and mulberry, but methods for specific identification of a particular tree host species- limited...

Temporal Patterns in Homalodisca spp. (Hemiptera: Cicadellidae) Oviposition on Southern California Citrus and Jojoba

A detailed study of the distribution of egg masses of Homalodisca vitripennis (Germar) and H. liturata Ball was done across a 2-yr period (2001-2003) on six host plants in southern California (Mars...

The Complex Biogeography of the Plant Pathogen Xylella fastidiosa: Genetic Evidence of Introductions and Subspecific Introgression in Central America

The bacterium Xylella fastidiosa is a plant pathogen with a history of economically damaging introductions of subspecies to regions where its other subspecies are native. Genetic evidence is presen...

Vitis caribaea as a source of resistance to Pierce's disease in breeding grapes for the tropics

A native Costarican vine, Vitis caribaea, was found growing unaffected by Pierce's disease (PD; Xylella fastidiosa) in the forests surrounding a dying V. vinifera plantation. V. caribaea was tested...

Xylella fastidiosa CoDiRO strain associated with the olive quick decline syndrome in southern Italy belongs to a clonal complex of the subspecies pauca that evolved in Central America

Xylella fastidiosa, a xylem-limited bacterium transmitted by xylem-fluid-feeding Hemiptera insects, causes economic losses of both woody and herbaceous plant species. A Xyl. fastidiosa subsp. pauca...
