GenomicsThe GATA transcription factor GtaC regulates early developmental gene expression dynamics in Dictyostelium
In many developmental systems, morphogenesis is coupled with dramatic changes in spatiotemporal gene expression, often orchestrated by the coordinated action of transcription factors. Development of the social soil amoebae Dictyostelium discoideum proceeds through a sequence of morphological and tra...

TranscriptomicsAllorecognition, via TgrB1 and TgrC1, mediates the transition from unicellularity to multicellularity in the social amoebae Dictyostelium discoideum
The social amoeba Dictyostelium discoideum integrates into a multicellular organism when individual starving cells aggregate and form a mound. The cells then integrate into defined tissues and develop into a fruiting body that consists of a stalk and spores. Aggregation is initially orchestrated by ...

TranscriptomicsBacterial discrimination by Dictyostelid amoebae reveals the complexity of ancient interspecies interactions
Transcriptional profiling of D. discoideum revealed sets of genes whose expression is enriched in amoebae interacting with different species of bacteria, including sets that appear specific to amoebae interacting with Gram(+), or with Gram(-) bacteria. In a genetic screen utilizing the growth of mut...

TranscriptomicsLeaps and lulls in the developmental transcriptome of Dictyostelium discoideum
Development of the soil amoeba Dictyostelium discoideum is triggered by starvation. When placed on a solid substrate, the starving solitary amoebae cease growth, communicate via extracellular cAMP, aggregate by tens of thousands and develop into fully integrated multicellular organisms. Early phases...

TranscriptomicsTranscriptome conservation of the D. discoideum and D. purpureum developmental programs revealed through RNA-sequencing
Cross species comparison of genomes and transcriptomes is a powerful tool for understanding underlying biological processes, accurate functional classification of genes, and discovery of novel elements. The shift to next-generation sequencing platforms has tremendously accelerated the analysis of ge...

TranscriptomicsNucleocytoplasmic shuttling of a GATA transcription factor functions as a development timer
Biological oscillations are observed at many levels of cellular organization. In the social amoebae Dictyostelium discoideum, starvation-triggered multicellular development is organized by periodic cAMP waves, which provide both chemoattractant gradients and developmental signals. We report that Gta...
