Chromosome rearrangements in Dictyostelium discoideum.
A tandem duplication (D350(III,III] of the whiB to radB interval of linkage group III has been characterized. The gene order on the duplication-bearing chromosome is: centromere, whiB500, radB+, whiB+, radB24, bsgA5, acrC4. Slow-growing, duplication-bearing strains (yellow-spored, radiation-resistant) produced four classes of faster growing sectors involving the whiB and radB loci: white-spored...
متن کاملA high-resolution HAPPY map of Dictyostelium discoideum chromosome 6.
We have made a high-resolution HAPPY map of chromosome 6 of Dictyostelium discoideum consisting of 300 sequence-tagged sites with an average spacing of 14 kb along the approximately 4-Mb chromosome. The majority of the marker sequences were derived from randomly chosen clones from four different chromosome 6-enriched plasmid libraries or from subclones of YACs previously mapped to chromosome 6....
متن کاملDictyostelium
How do the amoebae know where to go? Amoebae are chemotactic: they can sense gradients of certain chemicals and move along them. Dicty is known to chemotax to two chemicals: folic acid, which is released by bacteria and used in the hunt for food, and cAMP, which is released by amoebae during starvation and used to find each other during aggregation. Cells have evolved a relay mechanism in which...
متن کاملLocalization and organization of protein factors involved in chromosome inheritance in Dictyostelium discoideum.
Heterochromatin protein 1 (HP1) proteins are highly conserved heterochromatin components required for genomic integrity. We have previously shown that the two HP1 isoforms expressed in Dictyostelium, HcpA and HcpB, are mainly localized to (peri-)centromeric heterochromatin and have largely overlapping functions. However, they cause distinct phenotypes when overexpressed. We show here that these...
متن کاملDifferential effects of heterochromatin protein 1 isoforms on mitotic chromosome distribution and growth in Dictyostelium discoideum.
Heterochromatin protein 1 (HP1) is a well-characterized heterochromatin component conserved from fission yeast to humans. We identified three HP1-like genes (hcpA, hcpB, and hcpC) in the Dictyostelium discoideum genome. Two of these (hcpA and hcpB) are expressed, and the proteins colocalized as green fluorescent protein (GFP) fusion proteins in one major cluster at the nuclear periphery that wa...
