Plant Direct Q&A with Judy Brusslan
Plant Direct: Author ProfilesWhat does your lab work on?
My lab is interested in the regulation of leaf senescence (LS). As leaves sequentially age, they enter a regulated dismantling process that exports nutrients to growing and storage organs.
Tell us about the key findings from your recent article in Plant Direct.

Comparative profiling examines roles of DNA regulatory sequences and accessible chromatin during cold stress response in grasses
Research, The Plant Cell, The Plant Cell: In BriefPhysical access to regulatory DNA, including cis-regulatory sequences found within proximal promoters and distal enhancer elements, is a vital property of chromatin. In turn, their access is determined by nucleosome occupancy and post-translational modification of histone proteins. A continuum of chromatin…

Close Encounters of the ARF Kind: Proximity-based ARF1 GTPase Activity Regulates Vesicle Trafficking
Research, The Plant Cell, The Plant Cell: In BriefADP-RIBOSYLATION FACTOR (ARF) proteins play essential roles in vesicle trafficking by regulating the formation of membrane vesicles that move cargo throughout the cell. Their activity is controlled by specific guanine exchange factors (ARF-GEFs) that activate ARFs by catalyzing a GDP to GTP exchange…

Review: Emerging mechanisms to fine-tune receptor kinase signaling specificity (COPB)
Plant Science Research WeeklyMaybe it’s because I’ve spent too much time in lockdown, but sometimes I find studies on cell signaling a bit impenetrable. Fortunately, this excellent review by Galindo-Trigo et al. has arrived, which elegantly walks the reader through the crowded world of receptor-like kinases and “how cells…
Modifying plant photosynthesis and growth via simultaneous chloroplast transformation of Rubisco large and small subunits (Plant Cell)
Plant Science Research WeeklyIn an interesting evolutionary artifact, the genes encoding the small subunit of Rubisco, rbcS, reside in the nuclear genome, whilst those encoding RbcL persists in the chloroplast. The RbcS protein is translocated into the chloroplast where the holoenzyme forms. This complexity adds to the challenge…
