The interaction between plants and pathogens is often described as an evolutionary arms race, in which plants develop multilayered immune signaling to counteract direct extracellular attacks and intracellular chemical effectors. The type III secretion system (T3SS) of Gram-negative bacteria serves as…

The soil microbiome harbors a vast diversity of microorganisms that can be pathogenic, beneficial, or commensal to plants. A fundamental question in plant biology is how plants actively detect, differentiate, and optimize their associations with the microbiome to maintain optimal fitness. In a recent…

Plants and pathogens are locked in a co-evolutionary arms race. Pathogens secrete effectors into plants, leading to effector-triggered susceptibility. Plants in turn respond through the production of reactive oxygen species (ROS) and the expression of defence-related genes to defend themselves, which…

Memory—a mysterious cognitive process that retains information over time and shapes future interpretations and actions—is not exclusive to animals. In plants, a similar phenomenon occurs where past exposure to environmental stressors is “memorized,” enabling plants to respond more effectively…

Single cell mutiomics are radically changing our understanding of pretty much every cellular process. Here, Nobori et al. integrated single-cell transcriptomic, epigenomic and spatial transcriptomic data to investigate plant responses to pathogens. The authors used three different strains of Pseudomonas…

Although clusters of functionally related genes are common in prokaryotes, until recently it was thought that they were not a feature of eukaryotic genomes. However, several studies have identified biosynthetic gene clusters (BGCs) in plants. Many of these gene clusters include sets of enzymes that act…

Don’t miss this exciting Virtual Issue from New Phytologist on “plant-microbe-microbe” interactions. That’s not a typo – many of the articles address the signals that coordinate such multi-factorial interactions, as there is a growing recognition that interrelations between microbes influence…

Have you ever wondered how cells distinguish between the diverse array of external signals traveling through similar pathways? To understand the intricacies of plant signaling mechanisms, Ma et al. used single endodermal cells of Arabidopsis roots as a model to compare two receptor pathways. One pathway…
