Balance Under Stress: A Case of Mixed Signals
Blog, Plant Physiology, Plant Physiology: News and Views, ResearchPlants may appear to be sitting ducks to whatever pest, pathogen or bad weather assaults them, but they are far from defenseless. In fact, plants are artful masters of war, armed with elaborate physical and chemical defense systems. But, in many cases, optimizing growth and defense is like running a…
Resistance on Tap: PDR Transporters Direct Antimicrobial Metabolites Towards Invading Pathogens
Research, The Plant Cell, The Plant Cell: In BriefIn Arabidopsis thaliana and related species within the Mustard family (Brassicaceae), the tryptophan (trp)-derived antimicrobial metabolite camalexin (3-thiazol-2-yl-indole) plays a central role in defense against bacterial, fungal, and oomycete pathogens. Upon pathogen attack, cytochrome P450 monooxygenases…
Part of the Stack; How Does a Protein Know its Place?
Research, The Plant Cell: In a NutshellParsons et al. successfully separate early to late Golgi cisternae to reveal the sequential localization of resident proteins and the sequence features that guide transmembrane proteins within the Golgi stack. Plant Cell https://doi.org/10.1105/tpc.19.00081

Review: Sulfated plant peptide hormones (J. Exp. Bot)
Plant Science Research WeeklyIt’s hard to believe that when I was a student we were taught that “plants don’t have peptide hormones”. Since then we’ve discovered many diverse families of plant peptide hormones (see the Teaching Tool on peptide hormones for an excellent overview). Here, Kaufmann and Sauter review one family,…
Perspective: Grazing animals drove domestication of grain crops (Nature Plants)
Plant Science Research WeeklyHere’s an interesting question: Without human intervention, why would one find a dense stand of plants, growing in rather nutrient-rich soil? Perhaps you recognized that these conditions suggest seed dispersal by endozoochory, which involves passage through an animal's digestive tract. Spengler and…
COP1 can be hijacked by photoreceptors via their VP motifs (EMBO J)
Plant Science Research WeeklyPlant development is characterized by a high degree of plasticity in response to light. Light‐activated plant photoreceptors bind and inhibit the E3 ubiquitin ligase COP1, thus protecting downstream transcription factors from degradation. However, the detailed mechanisms of how COP1 can function between…
Plasma membrane-associated receptor like kinases relocalize to plasmodesmata in response to osmotic stress (Plant Phys)
Plant Science Research WeeklyPlasmodesmata are channels through the cell wall that allow molecules and substances to move back and forth as needed; they also play a central role in growth, development and defence of all higher plants. In this study, Grison et al. describe the rapid relocation to the plasmodesmata pores of two plasma…
