DETECTION AND IDENTIFICATION OF PHYTOPATHOGENIC XANTHOMONAS STRAINS BY AMPLIFICATION OF DNA-SEQUENCES RELATED TO THE HRP GENES OF XANTHOMONAS-CAMPESTRIS PV VESICATORIA
Three pairs of oligonucleotide primers specific for different regions of the hrp gene (hypersensitive reaction and pathogenicity) cluster of Xanthomonas campestris pv. vesicatoria were designed and...
DEVELOPMENT OF A POLYMERASE CHAIN-REACTION PROTOCOL FOR DETECTION OF XYLELLA-FASTIDIOSA IN PLANT-TISSUE
A 7.4-kb EcoRI fragment of genomic DNA of Xylella fastidiosa strain PCE-RR (ATCC 35879) was used as a probe and was conserved in 18 strains of Xylella. The nucleotide sequence of a 1.0-kb internal ...
ISOLATION AND PRELIMINARY CHARACTERIZATION OF EXTRACELLULAR PROTEASES PRODUCED BY STRAINS OF XYLELLA-FASTIDIOSA FROM GRAPEVINES
Virulent and weakly virulent grape strains of Xylella fastidiosa grew well on PD3 amended with gelatin and produced zones of hydrolysis on this medium, indicating the presence of proteolytic activi...
