Widespread premature transcription termination of Arabidopsis thaliana NLR genes by the spen protein FPA

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/P-TEFb snRNP controls ultraviolet radiation-induced transcriptional reprogramming

- 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

BORDER proteins protect expression of neighboring genes by promoting 3' Pol II pausing in plants

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 …

CCA: An R Package to Extend Canonical Correlation Analysis

Canonical correlations analysis (CCA) is an exploratory statistical method to highlight correlations between two data sets acquired on the same experimental units. The cancor() function in R (R Development Core Team 2007) performs the core of …
