TranscriptomicsTranscription profiling of Arabidopsis FACS sorted root specific cell types after nitrogen treatment
The organs of multicellular species are comprised of cell types that must function together to perform specific tasks. One critical organ function is responding to internal or external change but little is known about how responses are tailored to specific cell types or coordinated among them on a g...

TranscriptomicsTranscription profiling of Arabidopsis Pwer::GFP protoplasts with over-expressed dominant negative mutant isoforms of Aux/IAA transcription factors
Transient genetic modification of plant protoplasts is a straightforward and rapid technique for the analysis of numerous aspects of plant biology. One drawback in the analysis of transformed protoplast suspensions is that they are a heterogeneous mix of cells that have and have not been successfull...

TranscriptomicsTranscription profiling of Arabidopsis reveals organ regeneration in plants is independent of stem cell niche activity
A critical step in regeneration is recreating the cellular identities and patterns of lost organs long after embryogenesis is complete. In plants, perpetual (indeterminate) organ growth occurs in apical stem cell niches, which have been shown to re-establish quickly when damaged or removed (1,2). He...

TranscriptomicsA systemic view of coordinated root responses to NO3- heterogeneous environment in Arabidopsis
We investigated the morphological roots decisions of Arabidopsis in a NO3- heterogeneous medium. To do so, we used the Split-Root System which is an experimental set up to assess root decisions in nutrient heterogeneous medium. Split-root plants have been subjected to three different treatments. ‘Co...

TranscriptomicsHit-and-run transcriptional control by bZIP1 mediates rapid nutrient signaling in Arabidopsis
To identify potential transient interactions between a TF and its targets, we developed an approach that can identify primary targets based either on TF-induced regulation or TF-binding, assayed in the same samples. Our studies focused on the TF bZIP1 (BASIC LEUCINE ZIPPER 1), a central integrator o...
