Guest Editor : Suresh Damodaran I am a postdoctoral research associate in Dr. Lucia Strader’s lab at WUSTL. My primary area of interest is understanding the role of plant hormones in development. I completed my graduate degree in Dr. Sen Subramanian’s lab at SDSTATE.  Twitter: @SureshDamod   Design…

In recent months, a flurry of papers have come out that reveal new insights into the structural interactions of cell-surface receptors with each other and with their ligands. This timely review by Moussu and Santiago captures the highlights, in case you haven’t been following along. The review features…

SCHENGEN 3 [SGN3, also known as GASSHO1 (GSO1)] is a leucine-rich repeat receptor kinase (LRR-RK) previously shown to interact with CIF peptides (CASPARIAN STRIP INTEGRITY FACTORS) to regulate the development of the Casparian strip boundary in roots. Here, Okuda et al. characterize the CIF/LRR-RK interaction.…

RALFs (Rapid Alkalinization Factors, based on historical observations that they induce alkalization of the extracellular space) are signaling peptides with diverse roles. RALF4 is required for pollen tube growth and guidance through its interactions with CrRLK1Ls and leucine-rich extension (LRX) proteins.…

RALFs (Rapid Alkalinization Factors, based on historical observations that they induce alkalization of the extracellular space) are signaling peptides with diverse roles. RALFs have previously been shown to bind to the extracellular domain of (among others) FERONIA (FER), a member of the Catharanthus…

Osmotic stress in plants elicits many responses, one of which is increased accumulation of Ca2+ in the cytosol. Genes involved in this response have been identified, yet the mechanism behind the Ca2+ transport remains unknown. Maity et al. investigated the structure and function of the osmolality-sensitive…

The 2017 Chemistry Nobel Prize went to the developers of cryo-electron microscopy, and this method is transforming plant science as well as other life sciences. In a pair of back-to-back papers, Wang et al. used cryo-EM to examine how ZAR1, a CC-NLR protein [Coiled-coil (CC) nucleotide-binding (NB),…
