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…

The angle at which roots grow into the soil is modulated by the interaction between genetics and environment, and involves the gravity perception and response pathways including auxin transporters. Ogura et al. did a GWAS analysis of the gravitropic response of different Arabidopsis accessions in…

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…

Marchantia polymorpha is an emerging model for plant molecular biology and has contributed to studies on development and plant-microbe interactions. Here, using RNA-seq and proteomics, Carella et al. present a detailed time-course analysis of Marchantia molecular responses to pathogen infection triggered…

Plants are sessile organisms that have evolved sophisticated immune systems in defense of pathogens, thus maximizing the chance of survival. Most of our understanding of plant defenses comes from studies in angiosperms. Evolutionary molecular plant-microbe interactions (EvoMPMI) can reveal the origins…

The remarkable adaptations of Venus flytrap traps enable them to sense and respond to insects, snapping shut to capture and then digest the unfortunate meal. Previous studies showed that the sensors, trigger hairs on the inner surface of the leaves, need at least two touches to initiate trap closure.…

Review: Formal description of plant morphogenesis ($) In recent years, a number of tools have been developed to describe and model plant morphogenesis, and these approaches have greatly informed our understanding of the molecular processes that underpin the control of growth. This excellent review…
