The obligate biotrophic pathogen Blumeria graminis f. sp. tritici (Bgt) is the cause of wheat powdery mildew, a foliar disease that results in significant yield loss in most wheat-growing regions across the globe. This research focuses on the identification and functional analysis of the powdery mildew…

Enhancing plant defense against pathogens and pests often incurs a cost to essential physiological functions such as growth and reproduction, creating a trade-off. This phenomenon is evident in genetic studies across various plant models and agricultural breeding programs. Salicylic acid (SA) is a well-known…

Plants, particularly long-lived trees, need to balance nutrient acquisition, herbivore and pathogen defence, and ultimately organic matter decomposition. The intricate relationship between these processes is crucial for the survival and growth of trees over their extended lifespans. Zheng et al. investigated…

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…
