Cloning and expression in Escherichia coli of pectinase genes of Erwinia carotovora subsp. carotovora [PDF]

Applied and Environmental Microbiology, 1985
Genes coding for an endo-pectate lyase, an exo-pectate lyase, and an endopolygalacturonase of Erwinia carotovora subsp. carotovora Ecc71 were cloned in Escherichia coli HB101, using the cosmid pHC79. The products of the cloned pectinase genes paralleled their counterparts in strain Ecc71 in isoelectric mobility, mode of substrate degradation, and ...

Novel Quorum-Sensing-Controlled Genes in Erwinia carotovora subsp. carotovora: Identification of a Fungal Elicitor Homologue in a Soft-Rotting Bacterium

Molecular Plant-Microbe Interactions, 2005
Seven new genes controlled by the quorum-sensing signal molecule N-(3-oxohexanoyl)-L-homoserine lactone (OHHL) have been identified in Erwinia carotovora subsp. carotovora.

Genotypic characterisation of the Erwinia genus by PCR-RFLP analysis of rpoS gene

Plant Protection Science, 2002
Genotypic characterisation of the members of the genus Erwinia, based on the PCR-RFLP analysis of a fragment of the rpoS gene was done. PCR primers deduced from described rpoS gene sequences of E.

Erwinia chrysanthemi: pectolytic bacterium causing soft rot outbreaks of arracacha in Brazil Erwinia chrysanthemi: bactéria pectolítica envolvida na "mela" da mandioquinha-salsa no Brasil

Pesquisa Agropecuária Brasileira, 2006
The objetive of this work was to identify the pectolytic bacteria associated with soft rot of arracacha roots in Brazil. From 1998 to 2001, 227 isolates of Erwinia spp.

Oligogalacturonide-Mediated Induction of a Gene Involved in Jasmonic Acid Synthesis in Response to the Cell-Wall-Degrading Enzymes of the Plant Pathogen Erwinia carotovora

Molecular Plant-Microbe Interactions, 1999
Identification of Arabidopsis thaliana genes responsive to plant cell-wall-degrading enzymes of Erwinia carotovora subsp. carotovora led to the isolation of a cDNA clone with high sequence homology to the gene for allene oxide synthase, an enzyme ...

Caracterização de bactérias do género Erwinia causando podridões em plantas ornamentais no Brasil.

Ornamental Horticulture, 1996
São descritas as ocorrências de fito-bacterioses em plantios comerciais, ocasionando podridão mole em seis espécies de plantas ornamentais. Testes bioquímicos, fisiológicos, culturais e de patogenicidade permitiram cons-tatar a ocorrência de Erwinia ...

Characterization of transposon insertion out- mutants of Erwinia carotovora subsp. carotovora defective in enzyme export and of a DNA segment that complements out mutations in E. carotovora subsp. carotovora, E. carotovora subsp. atroseptica, and Erwinia chrysanthemi [PDF]

Journal of Bacteriology, 1990
Soft-rotting Erwinia spp. export degradative enzymes to the cell exterior (Out+), a process contributing to their ability to macerate plant tissues. Transposon (Tn5, Tn10, Tn10-lacZ) insertion Out- mutants were obtained in Erwinia carotovora subsp. carotovora 71 by using plasmid and bacteriophage lambda delivery systems.

Quorum Sensing in the Plant Pathogen Erwinia carotovora subsp. carotovora: The Role of expREcc

Molecular Plant-Microbe Interactions, 2000
The production of the main virulence determinants of the plant pathogen Erwinia carotovora subsp. carotovora, the extracellular cell wall-degrading enzymes, is partly controlled by the diffusible signal molecule N-(3-oxohexanoyl)-l-homoserine lactone ...

Chromosomal mapping in Erwinia carotovora subsp. carotovora with the IncP plasmid R68::Mu [PDF]

Journal of Bacteriology, 1985
Conjugational gene transfer was established in Erwinia carotovora subsp. carotovora SCRI193 by using plasmid R68::Mu c+ to mobilize the chromosome into multiply mutant recipients. It was observed that although the plasmid alone mobilized markers randomly at a frequency of ca.

Peh Production, Flagellum Synthesis, and Virulence Reduced in Erwinia carotovora subsp. carotovora by Mutation in a Homologue of cytR

Molecular Plant-Microbe Interactions, 2003
Erwinia carotovora subsp. carotovora is a causal agent of soft-rot diseases in a wide variety of plants. Here, we have isolated a new regulatory factor involved in the virulence of E. carotovora subsp.
