... regulatory regions are simply depleted of nucleosomes, and other proteins bound at these regions may not cross-link to DNA as efficiently as histones. In either case, the physical fractionation of yeast ... regulatory regions of the yeast genome have a lower density of nucleosomes than other regions, and that there is an inverse correlation between nucleosome density and...

Further exploration of the links between the clock and these pathways will lead to a better understanding of ... circadian phases of peak transcript abundance of ethylene signaling and ethylene responsive genes. Interestingly, two key ethyl- ene signaling components, namely EIN3 (ETHYLEN...
