Interaction between plant agglutinins and Legionella species

Interaction between plant agglutinins and Legionella species.

Serogroups of Legionella pneumophila exhibited differential reactivities with plant agglutinin. Agglutination patterns were modified by growing the organisms in different media. The passage of four strains through guinea pigs did not result in altered reactivities with lectins or with plant agglutinins.

Use of heterophilic agglutinins in plant serology.

In previous communications it has been demonstrated that monogalactosyl diglyceride and the anionic chloroplasts lipids can be detected on the thylakoid membrane by specific antisera 1 _ 3 . The antigen determinants are of carbohydrate nature as was shown by specific agglutination inhibition tests. They are located on the outer surface of the thylakoid membrane and are directly accessible to th...

Species interaction mechanisms maintain grassland plant species diversity.

Development of theory has outpaced experimental tests for most maintenance of diversity mechanisms. Here we demonstrate how data from biodiversity-ecosystem functioning experiments can be used to determine the mechanisms that maintain plant species diversity. We hypothesized that grassland plant diversity is maintained by two classes of mechanisms: (1) equalizing mechanisms, which reduce asymme...

Interaction between Some Pasture Species and Two Hieracium Species

Possible control options are investigated for the introduced Hieracium weeds, particular problems in South Island high country, New Zealand. In a pot experiment regression of input to output ratios of above ground biomass over successive harvests, from binary mixtures was used to determine the competitive interaction between 13 pasture species and two Hieracium species, H. pilosella and H. prae...
