Cell surface receptor complexes act as the first line of defense in detecting pathogens and preventing invasion. Upon recognizing extracellular immunogenic patterns, a cascade of signaling relays occurs, mediated by phosphorylation events among a large array of membrane-associated proteins. These proteins…

Light influences essentially all aspects of plant growth and development. Furthermore, plants are likely to adjust their stress responses based on fluctuations in energy availability during the dark-light cycle. Lin et al investigated a hormone downstream component, ETHYLENE RESPONSE FACTOR 1 (ERF1),…

Host plants recognize diverse bacterial epitopes, known as microbe-associated molecular patterns (MAMPs), and respond with an immune reaction to control bacterial growth. However, most studies have focused on single bacterial epitopes, limiting our understanding of plant-bacteria interaction outcomes…

Plants rely on an array of mineral nutrients for their growth, development, and reproductive processes. The molecular mechanisms governing the uptake, translocation, storage, and utilization of these essential minerals are orchestrated by specific nutrient transporters and their associated regulatory…

Thiolation of tRNA adds a sulfur-containing nucleotide modification at the tRNA wobble position, which is necessary for efficient translation. Zheng et al. investigated the role of tRNA thiolation in plant immunity, revealing its necessity for robust defense responses in Arabidopsis. They identified…

The defensive alkaloid gramine, present in barley and other grass species, plays an important role in protecting the plant from insect damage but poses challenges for ruminant palatability. Breeding strategies balance these factors by maintaining the protective function and making the grain palatable…

The identification and characterization of resistosome complexes, formed by the oligomerization of intracellular nucleotide-binding leucine-rich repeat receptors (NLRs), has recently been a major focus in the field of plant immunity. Some NLR genes occur as head-to-head pairs encoding proteins that function…

In the interesting world of plant defenses, plants have secret weapons called defense metabolites that stay quiet until a pathogen comes knocking. Plants have evolved two-component chemical defence systems to protect against pathogens while striking a balance between growth promotion and defence mechanisms.…
