The polymerase-associated factor 1 complex modulates the growth-defense tradeoff in Arabidopsis

The salicylic acid receptor NPR1 mediates the degradation of PAF1, which interacts with HDACs to repress defense gene expression.

We also looked at the evolution of immune gene clusters (NLRs). We found these gene clusters tend to be syntenic within and across species, but the gene turnover at these loci is so high that it erodes 1:1 orthology between pennycress & Arabidopsis, leading to distinct NLR content across species. 6/
Figure 5 | Synteny between locations of NLR clusters in Arabidopsis (top) and pennycress ‘MN106’ (bottom). Stacked barplots represent NLR clusters (one block per gene), colored by N-terminal domain. Gray ribbons indicate synteny. Red ribbons indicate synteny between highly variable NLR genes (hvNLRs), and blue ribbons indicate synteny between non-hvNLRs.

A young woman with dark hair is on a roller coaster. She is looking over her shoulder at the camera behind her, clearly screaming. Whether she is screaming from fear, excitement, or both is unclear.

Protocol for immunofluorescence imaging of epitope-tagged protein in Arabidopsis shoot apical meristem

Proteins expressed in or translocated to the shoot apical meristem (SAM) often play pivotal roles in regulating plant development. Here, we present a step-by-step protocol for immunofluorescence imaging to analyze epitope (FLAG)-tagged proteins in the Arabidopsis SAM. This technique may be suitable to visualize mobile proteins because small epitope tags are less disruptive than a relatively large fluorescent protein fusion. For complete details on the use and execution of this protocol, please r...

We always dreamed of automating seed phenotyping to save time and reduce user bias. But Arabidopsis seeds are tiny and often cluster, making analysis tricky—traditional imaging methods usually just excluded those clusters.

Our lab has a keen interest in hybridization barriers, such as those that occur in Arabidopsis when parents of different ploidy are crossed — a phenomenon often referred to as the "triploid block." Normal seeds appear light brown, plump, and healthy, whereas seeds from interploidy crosses do not.
