Pseudomonas aurantiaca ST-TJ4 against crown gall caused by Agrobacterium tumefaciens by inducing systemic resistance in cherry blossom

Biological Control
Cherry blossom crown gall has caused serious damage to plant growth, and is highly contagious and extremely difficult to control. The antagonism of pathogens by rhizosphere bacteria has attracted widespread attention.

Felons’ chattels and English living standards in the later fourteenth and fifteenth centuries

The Economic History Review, Volume 79, Issue 3, Page 1024-1051, August 2026.
Abstract The later fourteenth and fifteenth centuries have long occupied an intriguing and contested place in discussions of England's long‐run economic development. One key issue around which debate has coalesced is the living standards of the population as a whole and of different groups within it. We contribute to this debate by bringing forward new

Anatomical structure of moss leaves and their photosynthetic activity

Acta Societatis Botanicorum Poloniae, 2014
The photosynthetic activity of the leaf area unit increases depending on the degree of differentiation of the anatomical structure of the leaves of six chosen moss species. There is a correlation between the leaf area and the degree of differentiation of

Abnormal Accumulation of Sugars and Phenolics in Tobacco Roots Expressing the Agrobacterium T-6b Oncogene and the Role of These Compounds in 6b-Induced Growth

Molecular Plant-Microbe Interactions, 2007
The Agrobacterium T-DNA oncogene 6b induces tumors and modifies the growth of transgenic plants by an unknown mechanism. We have investigated changes in roots of tobacco seedlings that express a dexamethasone-inducible T-6b (dex-T-6b) gene.

Polyamine levels in crown gall tumour and teratoma

, 1992
The levels of polyamines in two morphological types of transformed tissue [crown gall tumour (undifferentiated) and teratoma (shooty tumour)] and of untransformed differentiating callus tissue growing in hormone-containing media were compared.

Deciphering the Key Players of the Bacterial Microbiota Associated with Aerial Crown Gall Tumors on Rhododendron: Insights into the Gallobiome

Phytobiomes Journal
Tumorigenic agrobacteria are widespread plant pathogens causing crown gall and cane gall diseases in various agricultural crops. These pathogens genetically transform the host plant and thus form an ecological niche (galls) in which specific metabolites (

Expression of a crown gall biological control phenotype in an avirulent strain of Agrobacterium vitis by addition of the trifolitoxin production and resistance genes

BMC Biotechnology, 2002
Background Agrobacterium vitis is a causal agent of crown-gall disease. Trifolitoxin (TFX) is a peptide antibiotic active only against members of a specific group of α-proteobacteria that includes Agrobacterium and its close relatives. The ability of TFX

Spatial distribution of Cynips quercusfolii (Hymenoptera: Cynipidae) galls on leaves and within the crowns of oak trees

European Journal of Entomology, 2013
The factors that affect oviposition and consequently spatial distribution of the galls of many gall makers are poorly understood. Knowledge of these factors could result in a better understanding of the mechanisms that initiate and regulate the ...
