The switch from mitotic cell cycles to the one meiotic cell cycle in each generation is triggered through dramatic upregulation of a broad gene expression program by transcriptional regulator STRA8.
A new technique called fastFISH enables nearly real-time and stoichiometric detection of nascent RNA and the tracking of individual stages of transcription at the level of single-molecules.
By properly accounting for gene copy number and cell-cycle effects, single cell snapshots of nascent and mature mRNA can be used to unveil the stochastic kinetics of gene activity.
Real-time single-molecule visualization of transcription and splicing in living cells reveals that RNA synthesis and processing can occur through multiple pathways on the same gene.
Two related DNA replication initiation proteins contribute to the decision of whether to enter a new round of the cell division cycle or enter into a period of proliferative quiescence.
Arabidopsis deploys the core signalling module that perceives distinct stress signals, such as DNA damage and heat stresses, and represses G2/M-specific genes, thereby causing cell cycle arrest.
Lin37 is essential for cell-cycle gene repression by the DREAM complex in cellular quiescence and a combined loss of Lin37 and Rb prevents cell-cycle exit in response to growth-limiting signals.
The formation of mutually exclusive coding and non-coding transcription units contributes to transcriptional interference and insulation at gene clusters and manages state-switching in response to environmental change.
