Photosynthetic Responses of a Temperate Liana to Xylella fastidiosa Infection and Water Stress
Xylella fastidiosa is a xylem-limited bacterial plant pathogen that causes bacterial leaf scorch in its hosts. Our previous work showed that water stress enhances leaf scorch symptom severity and progression along the stem of a liana, Parthenocissus quinquefolia, infected by X. fastidiosa. This paper explores the photosynthetic gas exchange responses of P. quinquefolia, with the aim to elucidat...
متن کاملDraft Genome Sequence of 11399, a Transformable Citrus-Pathogenic Strain of Xylella fastidiosa
The draft genome of Xylella fastidiosa subsp. pauca strain 11399, a transformable citrus-pathogenic strain, is reported here. The 11399 genome size is 2,690,704 bp and has a G+C content of 52.7%. The draft genome of 11399 reveals the absence of four type I restriction-modification system genes.
متن کاملQuantification of Xylella fastidiosa from Citrus Trees by Real-Time Polymerase Chain Reaction Assay.
ABSTRACT Xylella fastidiosa is the causal agent of citrus variegated chlorosis (CVC), a destructive disease of sweet orange cultivars in Brazil. Polymerase chain reaction (PCR)-based assays constitute the principal diagnostic method for detection of these bacteria. In this work, we established a real-time quantitative PCR (QPCR) assay to quantify X. fastidiosa in naturally and artificially infe...
متن کاملStable transformation of the Xylella fastidiosa citrus variegated chlorosis strain with oriC plasmids.
Xylella fastidiosa is a gram-negative, xylem-limited bacterium affecting economically important crops (e.g., grapevine, citrus, and coffee). The citrus variegated chlorosis (CVC) strain of X. fastidiosa is the causal agent of this severe disease of citrus in Brazil and represents the first plant-pathogenic bacterium for which the genome sequence was determined. Plasmids for the CVC strain of X....
متن کاملCitrus and Coffee Strains of Xylella fastidiosa Induce Pierce’s Disease in Grapevine
Pierce’s disease (PD) of grapevines (Vitis vinifera L.), caused by a strain of the bacterium Xylella fastidiosa (39), was first noted in California near Anaheim in 1884, and has been an important disease problem since that time in California. The disease prevents the cultivation of V. vinifera and French hybrid grapes in the southeastern United States, where the glassy-winged sharpshooter (GWSS...
