The hypothesis that crown gall tumorigenesis requires the formation of spheroplasts was tested by comparing the tumorinducing ability of populations of both permanent and revertable spheroplasts of Agrobacterium tumefaciens with that of popula tions of the typical rod form of the bacterium. Permanent spheroplasts produced by serial transfers in medium containing 0.005 MD-methionine did not prod...

BACKGROUND Rahnella aquatilis is ubiquitous and its certain strains have the applicative potent as a plant growth-promoting rhizobacteria. R. aquatilis HX2 is a biocontrol agent to produce antibacterial substance (ABS) and showed efficient biocontrol against crown gall caused by Agrobacterium vitis on sunflower and grapevine plants. The regulatory network of the ABS production and biocontrol ac...

The effects of cigarette smoking and parity on the development of symptomatic gall bladder disease remain controversial. These relations have been examined in a cohort of 46000 women followed for up to 19 years during the Royal College of General Practitioners' (RCGP) oral contraception study. During follow up, 1087 women were recorded as experiencing their first ever episode ofsymptomatic chol...

We have investigated the possibility that the abnormally decreased gall bladder contraction after meals in patients with coeliac disease might result in part from an abnormality in the gall bladder response to endogenous cholecystokinetic hormones--for example, cholecystokinin and motilin--rather than solely from decreased secretion of such hormones. Eight patients with untreated coeliac diseas...

INTRODUCTION Gall bladder is a pear shaped secular Organ which stores bile, is also place for formation and growth of gall stones. Today the incidence of Cholelithiasis is increasing considerably in India. The aim of our study are to know the incidence of gall stones in relation to age and sex, the relation of diet in gall stones, the clinical presentation of gall stones, the best mode of inves...

Crown gall tumors induced by Agrobacterium tumefaciens represent a sink that has to be provided with nutrients and water by the host plant. The lack of an intact epidermis or cuticle results in uncontrolled loss of water. However, neither the tumor nor the host plant displays wilting. This phenomenon points to drought adaptation in both tumors and the crown gall host plant. To understand the un...
