Electrophoretic karyotype for Dictyostelium discoideum.

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...

Foraging Strategies for Dictyostelium discoideum

The rate at which organisms are able to forage for food affects the rate at which they can grow, and thus foraging strategies are crucial for almost any organism. In the social amoeba Dictyostelium discoideum (Dicty), it is known that cell-cell communication plays an important role in aggregation of the cells, and thus we ask if it plays a similarly important role in foraging. In particular, we...

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...

Electrophoretic karyotype of Aspergillus nidulans.

An electrophoretic karyotype of Aspergillus nidulans has been obtained using contour-clamped homogeneous electric field gel electrophoresis. Six chromosomal bands were separated, with two of the bands migrating as doublets. Using the Schizosaccharomyces pombe and Saccharomyces cerevisiae chromosomes as size standards, we estimate the sizes of the chromosomes to be between 2.9 and 5.0 megabase p...
