Linking genotype to phenotype using the Arabidopsis unimutant collection

RC O'Malley, JR Ecker - The Plant Journal, 2010 - Wiley Online Library
The large collections of Arabidopsis thaliana sequence‐indexed T‐DNA insertion mutants
are among the most important resources to emerge from the sequencing of the genome. …

[HTML][HTML] Highly integrated single-base resolution maps of the epigenome in Arabidopsis

R Lister, RC O'Malley, J Tonti-Filippini, BD Gregory… - Cell, 2008 - cell.com
Deciphering the multiple layers of epigenetic regulation that control transcription is critical to
understanding how plants develop and respond to their environment. Using sequencing-by-…

[PDF][PDF] Cistrome and epicistrome features shape the regulatory DNA landscape

RC O'Malley, SC Huang, L Song, MG Lewsey… - Cell, 2016 - cell.com
The cistrome is the complete set of transcription factor (TF) binding sites (cis-elements) in an
organism, while an epicistrome incorporates tissue-specific DNA chemical modifications …

Transgenerational epigenetic instability is a source of novel methylation variants

RJ Schmitz, MD Schultz, MG Lewsey, RC O'Malley… - Science, 2011 - science.org
Epigenetic information, which may affect an organism’s phenotype, can be stored and
stably inherited in the form of cytosine DNA methylation. Changes in DNA methylation can …

[HTML][HTML] Epigenomic diversity in a global collection of Arabidopsis thaliana accessions

…, C Wang, F Bemm, C Becker, R O'Neil, RC O'Malley… - Cell, 2016 - cell.com
The epigenome orchestrates genome accessibility, functionality, and three-dimensional
structure. Because epigenetic variation can impact transcription and thus phenotypes, it may …

[HTML][HTML] A link between RNA metabolism and silencing affecting Arabidopsis development

BD Gregory, RC O'Malley, R Lister, MA Urich… - Developmental cell, 2008 - cell.com
MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) are abundant endogenous
small RNAs (smRNAs) that control transcript expression through posttranscriptional gene …
