Jasmonate signalling drives rapid local and systemic immunity establishment
Plant Science Research WeeklySystemic acquired resistance (SAR) provides plants with broad protection against many pathogens, but until recently, it was unclear how SAR signals are produced, transported, and expressed in distant tissues. In a new study in Nature Plants, Gaikwad and colleagues created a reporter construct that tracks…
Under attack: One reason why plants struggle in a warmer world
Plant Science Research WeeklyPlants, like animals, have a natural immune system that helps them defend against diseases. They not only fight local pathogens but can also alert distant, non-infected tissues to prepare for infection, a process called systemic acquired resistance (SAR). All these mechanisms can be threatened by climate…
Review: Salicylic acid in plant immunity and beyond
Plant Science Research WeeklySalicylic 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…
