Sisterson, M. S., Ledbetter, C. A., Chen, J., Higbee, B. S., Groves, R. L., and Daane, K. M. 2012. Management of almond leaf scorch disease: Long-term data on yield, tree vitality, and disease progress. Plant Dis. 96:1037-1044. Almond leaf scorch disease (ALSD) has been a chronic problem for California almond growers. This disease is caused by the bacterial pathogen Xylella fastidiosa and is tr...
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...
متن کاملSpatial Analysis of Almond Leaf Scorch Disease in the San Joaquin Valley of California: Factors Affecting Pathogen Distribution and Spread
Almond leaf scorch (ALS) disease has emerged recently as a serious threat to almond production areas throughout California’s San Joaquin Valley (5,36). This disease is caused by the xylem-limited bacterium Xylella fastidiosa, which also causes several plant diseases in California including Pierce’s disease (PD) of grape, oleander leaf scorch (OLS), and alfalfa dwarf (AD). X. fastidiosa bacteria...
متن کاملPopulation Structure of Xylella fastidiosa Associated with Almond Leaf Scorch Disease in the San Joaquin Valley of California.
Xylella fastidiosa causes disease in many commercial crops, including almond leaf scorch (ALS) disease in susceptible almond (Prunus dulcis). In this study, genetic diversity and population structure of X. fastidiosa associated with ALS disease were evaluated. Isolates obtained from two almond orchards in Fresno and Kern County in the San Joaquin Valley of California were analyzed for two succe...
