Journal ArticleDOI
PCR-mediated generation of a gene disruption construct without the use of DNA ligase and plasmid vectors
Hidekazu Kuwayama,Shinji Obara,Takahiro Morio,Mariko Katoh,Hideko Urushihara,Yoshimasa Tanaka +5 more
TL;DR: This method depends on DNA fragment fusion by the PCR technique and requires only two steps of PCR to obtain a sufficient amount of the gene disruption construct for one transformation experiment, and is simple, rapid and relatively inexpensive.
Journal ArticleDOI
Polymorphic Members of the lag Gene Family Mediate Kin Discrimination in Dictyostelium
Rocio Benabentos,Shigenori Hirose,Richard Sucgang,Tomaz Curk,Mariko Katoh,Elizabeth A. Ostrowski,Joan E. Strassmann,David C. Queller,Blaz Zupan,Blaz Zupan,Gad Shaulsky,Gad Shaulsky,Adam Kuspa +12 more
TL;DR: It is shown that lagB1 and lagC1 are highly polymorphic in natural populations and that their sequence dissimilarity correlates well with wild-strain segregation, revealing an early evolutionary origin of kin discrimination and providing insight into the mechanism of social recognition and immunity.
Journal ArticleDOI
Kin discrimination increases with genetic distance in a social amoeba.
Elizabeth A. Ostrowski,Mariko Katoh,Gad Shaulsky,Gad Shaulsky,David C. Queller,Joan E. Strassmann +5 more
TL;DR: It is demonstrated that D. discoideum cells co-aggregate more with genetically similar than dissimilar individuals, suggesting the existence of a mechanism that discerns the degree of genetic similarity between individuals in this social microorganism.
Journal ArticleDOI
A transcriptional profile of multicellular development in Dictyostelium discoideum.
Nancy Van Driessche,Chad A. Shaw,Mariko Katoh,Takahiro Morio,Richard Sucgang,Miroslava Ibarra,Hidekazu Kuwayama,Tamao Saito,Hideko Urushihara,Mineko Maeda,Ikuo Takeuchi,Hiroshi Ochiai,William Eaton,Jeffrey Tollett,John A. Halter,Adam Kuspa,Yoshimasa Tanaka,Gad Shaulsky +17 more
TL;DR: Analysis of the two differentiated cell types, spores and stalk cells, and their precursors revealed a large number of differentially expressed genes as well as unexpected patterns of gene expression, which shed new light on the timing and possible mechanisms of cell-type divergence.
Journal ArticleDOI
Developmentally regulated DNA methylation in Dictyostelium discoideum.
TL;DR: A role for a Dnmt2 methyltransferase in eukaryotic development is established, indicating that DNA methylation has a regulatory role in Dictyostelium development.
