Different Regulation and Roles of Lactonases AiiB and AttM in Agrobacterium tumefaciens C58
The phytopathogen Agrobacterium tumefaciens C58 expresses two lactonases, AttM and AiiB. We showed that expression of the aiiB gene was controlled by agrocinopines A and B and required the agrocinopine-ABC transporter Acc, but was not affected by the ...

Ecological Conditions and Molecular Determinants Involved in Agrobacterium Lifestyle in Tumors
The study of pathogenic agents in their natural niches allows for a better understanding of disease persistence and dissemination. Bacteria belonging to the Agrobacterium genus are soil-borne and can colonize the rhizosphere. These bacteria are also well

Healthy and Unhealthy Plant-Based Diets and Glioma in the Chinese Population
Plant-based diets have been suggested to help prevent various chronic diseases, including cancer. However, there are few reports on central nervous system tumors, and data on dose–response relationships are lacking.

Nucleoprotein Changes in Plant Tumor Growth [PDF]
Tumor cell transformation and growth were studied in a plant neoplasm, crown gall of bean, induced by Agrobacterium rubi. Ribose nucleic acid (RNA), deoxyribose nucleic acid (DNA), histone, and total protein were estimated by microphotometry of nuclei, nucleoli, and cytoplasm in stained tissue sections. Transformation of normal cells to tumor cells was

INDUCTION OF PLANT TUMORS BY ULTRAVIOLET RADIATION [PDF]
It was found that tumors can be induced in gametophytes of Pteridium aquilinum by exposing the dormant spores to ultraviolet radiation prior to germination. The tumor frequency increased linearly with dosage up to the level at which general viability of the spores was significantly affected. These ultraviolet-induced tumors were in every way comparable
