A Novel Group of -Like Agrobacteria Associated with Crown Gall Disease of Rhododendron and Blueberry.

Crown gall is an economically important and widespread plant disease caused by tumorigenic bacteria that are commonly affiliated within the genera , and . Although crown gall disease was reported to occur on rhododendron, literature data regarding this disease are limited. In this study, an atypical group of tumorigenic agrobacteria belonging to the genus was identified as a causative agent of crown gall on rhododendron.

Computational Modelling of Structures with Non-Intuitive Behaviour.

This paper presents a finite-element analysis of honeycomb and re-entrant honeycomb structures made of a two-phase composite material which is optimized with respect to selected parameters. It is shown that some distributions of each phase in the composite material result in the counter-intuitive mechanical behaviour of the structures. In particular, negative values of effective Poisson's ratio, i.

[Acute pancreatitis in children with acute lymphoblastic leukemia treated with L-asparaginase].

The treatment of the acute lymphoblastic leukemia in childhood includes frequent administration of L-asparaginase by intravenous route. L-asparaginase is an enzyme produced by E. coli and Erwinia chrysanthemi strains.
