Ziek en Zeer : Erwinia chrysanthemi in Amaryllidaceae

open access: yes, 2011
In dit artikel een verslag van het onderzoek naar de gevoeligheid van narcissen voor de bacterie Erwinia chrysanthemi (tegenwoordig Dickeya dadantii). Uit een infectieproef is gebleken dat deze bacterie tijdens een reguliere bollenteelt in Lisse niet in ...

External pH: An Environmental Signal That Helps to Rationalize pel Gene Duplication in Erwinia chrysanthemi

open access: yesMolecular Plant-Microbe Interactions, 2000
The phytopathogenic bacterium Erwinia chrysanthemi produces five major pectate lyases that are key virulence factors in soft-rot disease development. Using transcriptional fusions, we studied the regulation of pelA, pelD, and pelE gene expression as a ...

Erwinia chrysanthemi EC16 produces a second set of plant-inducible pectate lyase isozymes

open access: yes, 2014
The enterobacterium Erwinia chrysanthemi causes soft-rot diseases involving extensive tissue maceration in a wide variety of plants and secretes multiple pectic enzymes that degrade plant cell walls and middle lamellae. An E.

Population Behavior Analysis of dspE and pelD Regulation in Erwinia chrysanthemi 3937

open access: yesMolecular Plant-Microbe Interactions, 2006
Erwinia chrysanthemi 3937 (Ech3937) is a phytopathogenic bacterium with a wide host range. The pectinolytic enzymes secreted by the bacterium and the type III secretion system (T3SS) are essential for full virulence. We used the green fluorescent protein

Osmoregulated periplasmic glucan synthesis is required for Erwinia chrysanthemi pathogenicity

open access: yes, 2001
Erwinia chrysanthemi is a phytopathogenic enterobacterium causing soft rot disease in a wide range of plants. Osmoregulated periplasmic glucans (OPGs) are intrinsic components of the gram-negative bacterial envelope.

Identification of plant-inducible genes in Erwinia chrysanthemi 3937

open access: yes, 1990
We present a method for identifying plant-inducible genes of Erwinia chrysanthemi 3937. Mutagenesis was done with the Mu dIIPR3 transposon, which carries a promoterless neomycin phosphotransferase gene (nptI), so upon insertion, the truncated gene can ...
