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 ...
Anatomy and histology of reproductive organs of female Homalodisca coagulata (Hemiptera : Cicadellidae : Proconiini), with special emphasis on categorization of vitellogenic oocytes
The anatomy and histology of female Homalodisca coagulata (Say) (Hemiptera: Ci-cadellida: Proconiini) reproductive organs is described using light microscopy. The reproductive organs of H. coagulat...
Bacterial Leaf Scorch, a New Blueberry Disease Caused by Xylella fastidiosa
Since 2004, growers and scientists have observed a disorder described as "yellow twig" or "yellow stem" affecting a major selection of southern highbush blueberry, FL 86-19, in the south Georgia bl...
Biology and biometry of sharpshooter Homalodisca coagulata (Homoptera : Cicadellidae) reared on cowpea
Stage-specific survival, growth, developmental biology, and biometry of the sharpshooter Homalodisca coagulata (Say) were studied in the laboratory under controlled conditions of 27 ± 1°...
Colony morphology of Xylella fastidiosa almond leaf scorch strains
Xylella fastidiosa is the causal agent of almond leaf scorch disease (ALSD), which is currently reemerging in California as a potential threat to almond (Prunus dulcis) production. We previously re...
Comparative dispersal of Homalodisca coagulata and Homalodisca liturata (Homoptera : Cicadellidae)
California's viticulture and ornamental industries have suffered significant losses since the introduction of Homalodisca coagulata (Say), an important vector of the Pierce's disease bacterium. A b...
Complete Genome Sequence Data of Three Xylella fastidiosa subsp. multiplex Strains Isolated from Olive Trees in California, U.S.A.
Xylella fastidiosa is a xylem-limited bacterial plant pathogen that causes disease on numerous hosts. Additionally, X. fastidiosa asymptomatically colonizes a wide range of plant species. X. fast...
Cooperative efforts contained spread of Pierce's disease and found genetic resistance
An outbreak of Pierce's disease of grapevine in the Temecula Valley in the late 1990s was one in a decades-long series of sporadic appearances of this infection in California. However, the new outb...
DEVELOPMENT OF A FAST AMPLIFYRP ACCELER8 DIAGNOSTIC ASSAY FOR GRAPEVINE RED BLOTCH VIRUS
Polymerase chain reaction (PCR) is routinely used for the detection of grapevine red blotch virus (GRBV), a virus with a circular single-stranded DNA genome, in grapevine tissue. Since the preparat...
Differential Susceptibility of Prunus Germplasm (Subgenus Amygdalus) to a California Isolate of Xylella fastidiosa
Seedling peach (Prunus persica Batsch) and clonal peach-almond hybrids are popular rootstock choices for commercial almond growers in California. In this study, clonal replicates of peach and almon...
Do Sharpshooters From Around the World Produce the Same EPG Waveforms? Comparison of Waveform Libraries From Xylella fastidiosa (Xanthomonadales: Xanthomonadaceae) Vectors Kolla paulula (Hemiptera: Cicadellidae) From Taiwan and Graphocephala atropunctata From Californiae
When an exotic invasive species is a vector-borne plant pathogen, vector feeding behavior must be studied to identify potential host plant range and performance of specialized pathogen transmissi...
Effects of citrus and avocado irrigation and nitrogen-form soil amendment on host selection by adult Homalodisca vitripennis (Hemiptera : Cicadellidae)
Host plant water status is thought to influence dispersal of the xylophagous leafhopper Homalodisca vitripennis Germar, especially where plants are grown under high evaporative demand. Preference b...
