Flagellar Agglutinins
نویسنده
چکیده
1. Certain bacilli within one strain may lose their flagella and become non-motile. 2. The change in serological behavior associated with the change in motility indicates that the flagella possess an individual antigenic property. 3. Flagella can be separated from the bodies of the bacilli. 4. A strictly flagellar antiserum can be produced by the injection of a flagellar suspension. 5. This direct production of a strictly flagellar antiserum is proof of the existence in flagella of a separate specific antigen.

Light Affects Flagellar Agglutinability in Chlamydomonas eugametos by Modification of the Agglutinin Molecules.
The effect of light on the sexual competence of a light-sensitive mating type minus strain (mt(-)) of Chlamydomonas eugametos obtained by crossing a light-sensitive mating type plus strain (mt(+)) with a light-insensitive mt(-) strain is described. As previously demonstrated for the mt(+) parent, this study of one of the mt(-) offspring shows that (a) a light-sensitive mechanism affects flagell...
متن کاملWheat germ agglutinin induces mating reactions in Chlamydomonas eugametos by cross-linking agglutinin-associated glycoproteins in the flagellar membrane
Species-specific binding between the flagellar surfaces of mating types plus and minus (mt+ and mt-) gametes of Chlamydomonas eugametos is mediated by mating type-specific agglutinins. Their interaction triggers several mating responses that are necessary for cell fusion, such as flagellar twitching, flagellar tip activation, redistribution of agglutinin molecules to the flagellar tip (tipping)...
متن کاملFlagellar tip activation stimulated by membrane adhesions in Chlamydomonas gametes
Membrane adhesions between the flagella of mating-type "plus" and "minus" gametes of Chlamydomonas reinhardi are shown to stimulate a rapid change in the ultrastructure of the flagellar tips, designated as flagellar tip activation (FTA). A dense substance, termed fibrous tip material (FTM), accumulates between the flagellar membrane and the nine single A microtubules of the tip. The A microtubu...
متن کاملCell body and flagellar agglutinins in Chlamydomonas reinhardtii: the cell body plasma membrane is a reservoir for agglutinins whose migration to the flagella is regulated by a functional barrier
Fertilization in Chlamydomonas reinhardtii is initiated when gametes of opposite mating types adhere to each other via adhesion molecules (agglutinins) on their flagella. Adhesion leads to loss of active agglutinins from the flagella and recruitment of new agglutinins from a pool associated with the cell body. We have been interested in determining the precise cellular location of the pool and ...
متن کاملFlagellar adhesion-dependent regulation of Chlamydomonas adenylyl cyclase in vitro: a possible role for protein kinases in sexual signaling
Interactions between adhesion molecules, agglutinins, on the surfaces of the flagella of mt+ and mt- gametes in Chlamydomonas rapidly generate a sexual signal, mediated by cAMP, that prepares the cells for fusion to form a zygote. The mechanism that couples agglutinin interactions to increased cellular levels of cAMP is unknown. In previous studies on the adenylyl cyclase in flagella of a singl...
