New linear lipopeptides produced by Pseudomonas cichorii SF1-54 are involved in virulence, swarming motility, and biofilm formation.
TLDR
High-performance liquid chromatography analysis of P. cichorii SF1-54 revealed the presence of seven compounds with lipopeptide characteristics, and two nonribosomal peptide synthethase-encoding genes, cifA and cifB, were identified as responsible for cichofactin biosynthesis. Expand
Automated leaf temperature monitoring of glasshouse tomato plants by using a leaf energy balance model
In order to detect biotic and abiotic stress at leaf level thermal indices based on leaf temperature measurements have been commonly used. The application of these indices within glasshouse crops is,Expand
Pseudomonas cichorii as the causal agent of midrib rot, an emerging disease of greenhouse-grown butterhead lettuce in Flanders.
TLDR
Isolations from infected lettuces, collected from 14 commercial greenhouses in Flanders, yielded 149 isolates that were characterized polyphasically, which included morphological characteristics, pigmentation, pathogenicity tests by both injection and spraying of lettuce, LOPAT characteristics, FAME analysis, BOX-PCR fingerprinting, 16S rRNA and rpoB gene sequencing, as well as DNA-DNA hybridization.

Simultaneous response of stem diameter, sap flow rate and leaf temperature of tomato plants to drought stress
TLDR
Stem diameter, sap flow rate and leaf temperature measurements detected drought stress before visual symptoms were observed, so they can be implemented in an early-warning system. Expand
Epidemiology of Pseudomonas cichorii, the Cause of Lettuce Midrib Rot
TLDR
It was shown that symptom expression is strongly influenced by the lettuce cultivar group, irrespective of the P. cichorii isolate, resulting in varnish spot ⁄ tar on crisphead lettuce and midrib rot on butterhead or cutting group lettuce. Expand
Development of a real‐time PCR assay for Pseudomonas cichorii, the causal agent of midrib rot in greenhouse‐grown lettuce, and its detection in irrigating water
TLDR
A sensitive real-time PCR assay based on a 90-bp amplicon from the pathogenicity gene cluster hrcRST and a Taqman Minor Groove Binding probe proved to be valuable for detecting infective P. cichorii concentrations in the irrigation water of a commercial lettuce production greenhouse. Expand
Characterization of Cichopeptins, New Phytotoxic Cyclic Lipodepsipeptides Produced by Pseudomonas cichorii SF1-54 and Their Role in Bacterial Midrib Rot Disease of Lettuce.
TLDR
It is demonstrated that cichopeptins contribute to virulence of P. cichorii SF1-54 on lettuce by characterization of the structure of the two phytotoxic compounds. Expand
Modelling ontogenetic changes of nitrogen and water content in lettuce.
BACKGROUND AND AIMS It is well established that the nitrogen content of plants, including lettuce, decreases with time. It has also been observed that water content of lettuce increases betweenExpand
Pseudomonads associated with midrib rot and soft rot of butterhead lettuce and endive.
TLDR
Fluorescent pseudomonads with phenotype HR+ were consistently isolated from typical dark midrib rot symptoms, and selected isolates reproduced the typical mid rib rot symptoms when spray-inoculated onto healthy lettuce plants. Expand
