- BDR proteins repress expression of the floral repressor, FLC - BDR proteins physically interact with the autonomous pathway protein FPA - BDR-repressed genes have high levels of Pol II occupancy, despite low mRNA levels - Gene repression by BDR may involve the inhibition of transcription elongation
Genes involved in disease resistance are some of the fastest evolving and most diverse components of genomes. Large numbers of nucleotide-binding, leucine-rich repeat (NLR) genes are found in plant genomes and are required for disease resistance. …
- The 7SK snRNA is dispensable for cell proliferation under standard growth conditions - After UV exposure, 7SK/P-TEFb is needed for proper stress response and cell survival - P-TEFb extracted from 7SK/P-TEFb triggers UV-induced general RNAPII pause release - P-TEFb from 7SK/P-TEFb supports activation of important UV-responsive genes
Ensuring that one gene's transcription does not inappropriately affect the expression of its neighbors is a fundamental challenge to gene regulation in a genomic context. In plants, which lack homologs of animal insulator proteins, the mechanisms …
