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…

Temperature extremes, such as cold stress, severely affect wheat (Triticum aestivum) productivity and quality by impairing its vegetative and reproductive growth. Several phytohormones have roles in cold stress, such as brassinosteroids (BRs) and salicylic acid (SA). However, how BR interacts with SA…

Salicylic acid (SA) is a pivotal natural compound in plant science and finds applications in herbal medicine; specifically, aspirin, the renowned anti-inflammatory drug and pain reliever, is a derivative of SA. As summarized in this review by Spoel and Dong, within plants SA serves as a crucial phytohormone…

Plants are colonized by numerous beneficial microorganisms in the rhizosphere, including Pseudomonas fluorescens, that provide benefits including nutrient acquisition and pathogen protection. Host plants must tune their immune systems to restrict microbial overgrowth, while avoiding overstimulation of…

Gordon et al. report that knock-out of a recently discovered enzyme for salicinoid biosynthesis in poplar leads to changes in salicylic acid and jasmonic acid metabolism and has unexpected effects on growth..

Programmed cell death (PCD) plays roles in both developmental and environmental responses across plant species. During pathogen attack, the hypersensitive response can limit spread of infection by orchestrating an organised death of cells around the infection area. A recent study by Lukan et al. demonstrated…

He et al. demonstrate that Mediator complex subunits have functions beyond their known roles in transcription. Plant Cell https://doi.org/10.1093/plcell/koab079 By Huaming He, Patrick Willems, Frank Van Breusegem, and Amna Mhamdi Background: Plants often face challenging environments to which they…

Does a new job always come with a new location? Perhaps this is true for some plant proteins; half of the proteins are located in more than one subcellular compartment. Emerging evidence in plants shows that nuclear-encoded proteins undergo redox and posttranslational modifications or processing events…
