Multilocus sequence typing of Xylella fastidiosa causing Pierce's disease and oleander leaf scorch in the United States.
Using a modified multilocus sequence typing (MLST) scheme for the bacterial plant pathogen Xylella fastidiosa based on the same seven housekeeping genes employed in a previously published MLST, we studied the genetic diversity of two subspecies, X. fastidiosa subsp. fastidiosa and X. fastidiosa subsp. sandyi, which cause Pierce's disease and oleander leaf scorch, respectively. Typing of 85 U.S....
متن کاملfirst report of xylella fastidiosa associated with oleander leaf scorch in lebanon
symptoms of the leaf scorch disease on the leaves of oleander infected by xylella fastidiosa appearing for the first time in lebanon were confirmed by elisa tests and anatomical observations of sections of petioles by a scanning electron microscope. xylella fastidiosa was detected in the xylem forming bacterial aggregates in the lumen of tracheary elements. the bacterium colonizes and invades t...
متن کاملGenome Sequence of a Xylella fastidiosa Strain Causing Mulberry Leaf Scorch Disease in Maryland
Xylella fastidiosa causes bacterial leaf scorch in landscape trees, including mulberry. We determined the draft genome of the mulberry strain Mul-MD in order to gain a better understanding of the molecular basis of strain divergence, host specificity, nutrient requirements, and pathogenicity, as well as to develop genome-based specific detection methods.
متن کاملGenome Sequence of a Xylella fastidiosa Strain Causing Sycamore Leaf Scorch Disease in Virginia
Xylella fastidiosa causes bacterial leaf scorch in landscape trees including sycamore. We determined the draft genome of X. fastidiosa strain Sy-Va, isolated in Virginia from a sycamore tree displaying leaf scorch symptoms. The Sy-VA genome contains 2,477,829 bp, and has a G+C content of 51.64 mol%.
متن کاملTwo Xylella fastidiosa Genotypes Associated with Almond Leaf Scorch Disease on the Same Location in California.
ABSTRACT Almond leaf scorch disease (ALSD) has recently reemerged in the San Joaquin Valley of California threatening almond production. ALSD is caused by Xylella fastidiosa, a nutritionally fastidious bacterium. Single nucleotide polymorphisms (SNPs) in the 16S rRNA gene (16S rDNA) of X. fastidiosa strains were identified to characterize the bacterial population in infected trees. Genotype-spe...
