Putative Transcriptional Regulator LysR1 Is Required for Full Virulence of Erwinia amylovora

Plant Pathology, Volume 74, Issue 6, Page 1697-1706, August 2025.
Erwinia amylovora lysR1 transcription factor mutants have a sharply reduced ability to cause fire blight disease, not due to lysine auxotrophy but a deficiency in production of the virulence factor exopolysaccharide amylovoran. ABSTRACT Fire blight, caused by the gram‐negative bacterium Erwinia amylovora, is a serious disease of apple and pear trees ...

Differential Regulation of Two Oligogalacturonate Outer Membrane Channels, KdgN and KdgM, ofDickeya dadantii(Erwinia chrysanthemi) [PDF]

Journal of Bacteriology, 2007
ABSTRACTThe entry of oligogalacturonates intoDickeya dadantiioccurs through the specific channel KdgM. The genome of the bacterium encodes a second member of this family of outer membrane proteins, KdgN. We showed that this protein is also involved in the uptake of oligogalacturonates.

Natural pigments derived from plants and microorganisms: classification, biosynthesis, and applications

Plant Biotechnology Journal, Volume 23, Issue 2, Page 592-614, February 2025.
Summary Pigments, as coloured secondary metabolites, endow the world with a rich palette of colours. They primarily originate from plants and microorganisms and play crucial roles in their survival and adaptation processes. In this article, we categorize pigments based on their chemical structure into flavonoids, carotenoids, pyrroles, quinones ...

The two‐component system CpxA/CpxR regulates pathogenesis and stress adaptability in the poplar canker bacterium Lonsdalea populi

Molecular Plant Pathology, Volume 25, Issue 11, November 2024.
Lonsdalea populi CpxA/CpxR manipulates pathogenesis and stress response by influencing flagella formation and function, regulating the type III secretion system and modulating transcription of membrane protein‐coding gene yccA. Abstract Bacteria employ two‐component systems (TCSs) to rapidly sense and respond to their surroundings often and during ...

Evolution of glucuronoxylan side chain variability in vascular plants and the compensatory adaptations of cell wall–degrading hydrolases

New Phytologist, Volume 244, Issue 3, Page 1024-1040, November 2024.
Summary Polysaccharide structural complexity not only influences cell wall strength and extensibility but also hinders pathogenic and biotechnological attempts to saccharify the wall. In certain species and tissues, glucuronic acid side groups on xylan exhibit arabinopyranose or galactose decorations whose genetic and evolutionary basis is completely ...

Diversity within the novel Dickeya fangzhongdai sp., isolated from infected orchids, water and pears

, 2018
International audienceMembers of the genus Dickeya are plant pathogens that mostly cause soft-rot diseases. Diversity within the genus has led to the recent description of three novel species (i.e. a mainly clonal D.
