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 ...
