OCCURRENCE OF VASCULAR STEM ROT DISEASE ON GLOBE ARTICHOKE CAUSED BY ERWINIA CAROTOVORA IN EGYPT. [PDF]
During the summer of 2001, a vascular stem rot of artichoke (Cynara sco/ymus L) was reported. Gram negative, non sporulating bacteria were isolated from the affected lesions.

A mutant of Erwinia carotovora subsp. carotovora, AH2552, created by a Mud1 insertion was found to be reduced in plant pathogenicity and deficient in extracellular protease and cellulase activity, although it produced normal levels of pectate lyase and ...

recA is required in the induction of pectin lyase and carotovoricin in Erwinia carotovora subsp. carotovora [PDF]
Pectin lyase (PNL) and the bacteriocin carotovoricin (CTV) were induced in Erwinia carotovora subsp. carotovora 71 by the DNA-damaging agents mitomycin C, nalidixic acid, and UV light. To determine whether the recA product was involved in the expression of these damage-inducible phenotypes, we cloned the E. carotovora subsp.

Effects of a mutation that eliminates UDP glucose-pyrophosphorylase on the pathogenicity of Erwinia carotovora subsp. carotovora [PDF]
A nonpathogenic mutant of Erwinia carotovora obtained by Mu d1 mutagenesis was defective in the ability to utilize several carbon sources. The basis of the mutation was analyzed biochemically and shown to be a defect in the ability to form UDP glucose-pyrophosphorylase.

Affinity chromatography of exopolygalacturonate lyase from Erwinia carotovora subsp. carotovora. [PDF]
An exopolygalacturonate lyase (exo-PGL) was rapidly purified from the cells of E. carotovora subsp. carotovora with a modified cross-linked pectate (mdCLPA); the material CLPA was partially degraded by an endopolygalacturonase to increase its adsorption capacity, followed by reduction with sodium borohydride.

Construction and Damage Analysis of a Three‐Factor Collision Model for Potato‐Soil‐Pole
In this study, the potato‐soil‐pole three‐factor collision model was constructed with the potato‐soil ratio, impact velocity and impact object as the core factors, and a new coupled pole was designed to alleviate the impact damage. The potato‐soil finite element model was constructed by reverse engineering, and the deviation of the traditional ...
