The Kotodesh genotype of the nickel (Ni) hyperaccumulator Alyssum murale was examined to determine the compartmentalization and internal speciation of Ni, and other elements, in an effort to ascertain the mechanism used by this plant to tolerate extremely high shoot (stem and leaf) Ni concentrations. Plants were grown either hydroponically or in Ni enriched soils from an area surrounding an his...

In this paper we provide a step by step comparison of the pathogenesis of murine infection caused by reovirus type 3 (Dearing) and an antigenic variant (K) selected by its resistance to neutralization with a monoclonal antibody (G5) directed against the T3 hemagglutinin. To show that specific changes in the biologic properties of variant K were due to mutation in the S1 double-stranded RNA segm...

Lobularia maritima or sweet alyssum (Brassicaceae) is an annual littoral halophyte, naturally thriving on sandy beaches. In addition to its obvious interest as a salt-tolerant plant, this species mainly cultivated ornamental plant in many countries. Laboratory experiments were carried out assess the effects of salinity seed germination and recovery from saline conditions after transfer distille...
