molecular comparison of pathogenic bacteria from pear trees in japan and the fire blight pathogen erwinia amylovora. | several strains of the genus erwinia, which were isolated in japan from pear trees with necrotic symptoms that resembled fire blight, and tentatively identified as erwinia amylovora, were reinvestigated for their relationship to the fire blight pathogen. these isolates produced ooze on slices of immature pears and were mucoid on mm2cu agar plates, but did not synthesize levan and did not give the expected pcr signals with several primer pairs specific for erwinia amylovora. the isolates tested p ... | 2001 | 11700346 |
genotyping of bacteria belonging to the former erwinia genus by pcr-rflp analysis of a reca gene fragment. | genotypic characterization, based on the analysis of restriction fragment length polymorphism of the reca gene fragment pcr product (reca pcr-rflp), was performed on members of the former erwinia genus. pcr primers deduced from published reca gene sequences of erwinia carotovora allowed the amplification of an approximately 730 bp dna fragment from each of the 19 erwinia species tested. amplified reca fragments were compared using rflp analysis with four endonucleases (alui, hinfi, tasi and tru1 ... | 2002 | 11832521 |
erwinia mallotivora sp., a new pathogen of papaya (carica papaya) in peninsular malaysia. | erwinia mallotivora was isolated from papaya infected with dieback disease showing the typical symptoms of greasy, water-soaked lesions and spots on leaves. phylogenetic analysis of 16s rrna gene sequences showed that the strain belonged to the genus erwinia and was united in a monophyletic group with e. mallotivora dsm 4565 (aj233414). earlier studies had indicated that the causal agent for this disease was e. papayae. however, our current studies, through koch's postulate, have confirmed that ... | 2010 | 21339975 |
draft genome sequence of erwinia mallotivora bt-mardi, causative agent of papaya dieback disease. | erwinia mallotivora was isolated from papaya trees infected with dieback disease, which were planted at the malaysian agricultural research and development institute (mardi), malaysia. here, we report a draft genome sequence of e. mallotivora bt-mardi, which offers an important source of information for understanding pathogen and host interaction during papaya dieback development. | 2014 | 24812220 |
