Understanding the transcriptional regulatory circuitry responsible for pluripotency and self-renewal in embryonic stem (ES) cells is fundamental to understanding human development and realizing the therapeutic potential of these cells. The transcription factor Oct4 and the chromatin-modifying Polyc...
ORGANISM(S): Homo sapiens 
Embryonic stem cells have a unique regulatory circuitry, largely controlled by the transcription factors Oct4, Sox2 and Nanog, which generates a gene expression program necessary for pluripotency and self-renewal (Boyer et al. 2005; Loh et al. 2006; Chambers et al. 2003; Mitsui et al. 2003; Nichols ...
ORGANISM(S): Mus musculus 
Polycomb group (PcG) proteins are highly conserved from flies to mammals and many of these factors have essential roles in early embryonic development. PcG proteins comprise two multimeric complexes, the Polycomb Repressive complexes 1 and 2 (PRC1 and 2), which have been shown to repress transcript...

F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor which form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants which have a F1€“like phenotype, we have by...
