Immunodominant carbohydrate determinants in the multicellular stages of Dictyostelium discoideum

Developmentally regulated, carbohydrate-binding protein in Dictyostelium discoideum.

A carbohydrate-binding protein assayed by its ability to agglutinate formalinized sheep erythrocytes is synthesized between 3 and 9 hr after Dictyostelium discoideum cells are deprived of food, as the cells become cohesive. Agglutination of erythrocytes by this protein was inhibited by N-acetyl-D-galactosamine, D-galactose, and L-fucose, but other monosaccharides had little or no effect. The pr...

Cost of movement in the multicellular stage of the social amoebae Dictyostelium discoideum and D. purpureum

Dictyostelium discoideum

Dictyostelium discoideum is a cellular slime mold [4] that serves as an important model organism [5] in a variety of fields. Cellular slime molds have an unusual life cycle. They exist as separate amoebae, but after consuming all the bacteria in their area they proceed to stream together to form a multicellular organism. These features make them a valuable tool for studying developmental proces...

influx in Dictyostelium discoideum

Translocations in Dictyostelium discoideum.

Fourteen translocations of independent origin were identified in Dictyostelium discoideum on the basis of segregation anomalies of diploids heterozygous for these chromosome rearrangements, all of which led to the cosegregation of unlinked markers. Many of these translocations were discovered in strains mutagenized with MNNG or in strains carrying mutations affecting DNA repair; however, sponta...
