Reversal of an immunity associated plant cell death program by the growth regulator auxin

, 2007
One form of plant immunity against pathogens involves a rapid host programmed cell death at the site of infection accompanied by resistance, termed the hypersensitive response (HR).

Mapping of Fire Blight Resistance QTL in the European Pear (Pyrus communis L.) Cultivar ‘Petersbirne’

Plant Breeding, EarlyView.
ABSTRACT The breeding of pear (Pyrus communis) cultivars that meet market requirements and are at the same time resistant to fire blight is a challenging task beacuse appropriate resistance donors are scarce. To identify valuable resistance sources, phenotypic screening and genetic characterization are indispensable.

Erwinia plantamica sp. nov., a Non-Phytopathogenic Bacterium Isolated from the Seedlings of Spring Wheat (Triticum aestivum L.)

Microorganisms
Erwinia are widely known as phytopathogenic bacteria, but among them, there are also plant-friendly strains that can promote plant growth (PGPR). The Erwinia-like strain OPT-41 was isolated from Triticum aestivum seedlings as a potential PGPR. The cells (

Characterization of plasmids in Erwinia stewartii [PDF]

Applied and Environmental Microbiology, 1981
Plasmids in 39 strains of Erwinia stewartii were examined by agarose gel electrophoresis. Most virulent strains had from 11 to 13 plasmids ranging in molecular mass from 2.8 to 210 megadaltons and contained plasmids of 210, 70, 49, 43, 29.5, 16.8, 8.8, and 2.8 megadaltons. Plasmids in strains SW2 and SS104 were characterized by both electron microscopy

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

Genome analysis of Erwinia persicina reveals implications for soft rot pathogenicity in plants

Frontiers in Microbiology, 2022
Soft rot disease causes devastating losses to crop plants all over the world, with up to 90% loss in tropical climates. To better understand this economically important disease, we isolated four soft rot-causing Erwinia persicina strains from rotted ...

The grapevine microbiota: A review on the possible impacts of plant protection programs on phyllosphere microorganisms

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
This review highlights recent advances in understanding how plant protection programs and alternative fungicides affect the taxonomic composition of the grapevine phyllosphere microbiota. Bacterial and fungal communities are primarily shaped by the plant compartment, vineyard location, and sampling time. Plant protection programs generally have a minor
