Historically the genus Erwinia has served as a repository for plant-pathogenic or plant-
associated bacteria (25, 96, 128). Consequently, diverse bacteria that occupy different …

Diverse interactions between hosts and microbes are initiated by the detection of host-
released chemical signals. Detection of these signals leads to altered patterns of gene …

The soft rot erwiniae, Erwinia carotovora ssp. atroseptica (Eca), E. carotovora ssp.
carotovora (Ecc) and E. chrysanthemi (Ech) are major bacterial pathogens of potato and …

Erwinia chrysanthemi is an enterobacterium that causes various plant diseases. Its
pathogenicity results from the secretion of pectinolytic enzymes responsible for the …

Streptomyces are Gram-positive microorganisms able to adapt and respond to different
environmental conditions. It is the largest genus of Actinobacteria comprising over 900 …

Members of the IclR family of regulators are proteins with around 250 residues. The IclR
family is best defined by a profile covering the effector binding domain. This is supported by …

The production of extracellular enzymes such as pectate lyase (Pel), polygalacturonase
(Peh), cellulase (Cel), and protease (Prt) is activated by the cell density (quorum)-sensing …

The plant pathogen Erwinia chrysanthemi produces three acyl‐homoserine lactones (acyl‐
HSLs). One has been identified as N‐(3‐oxohexanoyl)‐homoserine lactone (OHHL), and …

The enterobacterium Erwinia carotovora ssp. carotovora strain 71 (hereafter Ecc71)
produces extracellular enzymes such as pectate lyase isozymes (Pels), cellulase (Cel) …

Production of the plant hormone indole-3-acetic acid (IAA) is widespread among plant-
associated microorganisms. The non-gall-forming phytopathogen Erwinia chrysanthemi …
