Succinamopine: a new crown gall opine [PDF]

Journal of Bacteriology, 1984
Agrobacterium tumefaciens strains can incite plant tumors consisting of transformed cells that synthesize novel metabolites called opines. The pattern of opine synthesis is dictated by plasmid-borne genes in the pathogen; additional plasmid genes confer on the pathogen the ability to catabolize the same pattern of opines synthesized.

Pathogenic fungus Ustilago maydis exploits the lateral root regulators to induce pluripotency in maize shoots

New Phytologist, Volume 249, Issue 6, Page 2974-2985, March 2026.
Summary Biotrophic plant–pathogens secrete effector molecules to redirect and exploit endogenous signaling and developmental pathways in their favor. The biotrophic fungus Ustilago maydis causes galls on all aerial parts of maize. However, the responsible gall‐inducing effectors and corresponding plant signaling pathway(s) remain largely unknown.

The Rhus chinensis Genome Provides Insights Into Tannin, Flavonoid Biosynthesis, and Glandular Trichome Development

Plant Biotechnology Journal, Volume 24, Issue 3, Page 988-1013, March 2026.
ABSTRACT The “salt tree”, Rhus chinensis, holds significant economic and medicinal value due to its ability to produce Galla chinensis (Chinese gall/gallnut), a plant‐derived medicinal material used in both traditional Chinese and modern medicine that is rich in tannins and flavonoids. It is also renowned for its remarkable stress tolerance.

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.

The tasiR‐ARF pathway in plants: origin, functions, and interplay of miR‐390, tasiRNAs and ARF3

Plant Biology, Volume 28, Issue 2, Page 328-344, March 2026.
Trans‐acting small interfering RNAs that silence a subset of Auxin Response Factors are crucial for plant growth, developmental timing, proper organ patterning, and coping with stress. Abstract Trans‐acting small interfering RNA (tasiRNAs) are a special type of endogenous small RNAs (sRNAs) found only in plants.

Susceptibility of chrysanthemum (Dendranthema grandiflora Tzvelev) cultivars to crown gall [Agrobacterium tumefaciens (Smith et Townsend) Conn]

Acta Agrobotanica, 2012
The susceptibility of 29 cultivars of chrysanthemum, representing various types of growth, to crown gall was studied. Two isolates of Agrobacterium tumefaciens: chrysanthemum and apple were used for testing plants.

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, Volume 13, Issue 10, 18 February 2026.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

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

Biological Flora of Britain and Ireland: Geranium sylvaticum*

Journal of Ecology, Volume 114, Issue 2, February 2026.
Geranium sylvaticum is a perennial forb of upland grasslands, woodlands and riverbanks in northern Britain, with scattered native occurrences also in Wales, central England and Northern Ireland. It has an extensive native range in Europe and Asia. The species is gynodioecious, with individual plants typically female or hermaphrodite.

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.
