Systemic immunity, where local plant interactions with microbes or insects trigger enhanced resistance in distant organs, has parallels to the nervous system in animals. In plants, GLUTAMATE RECEPTOR-LIKE (GLR) genes have a pivotal role in long-distance wound signal transmission and the initiation of defense mechanisms including the accumulation of the defense hormone jasmonate (JA) at […]
Phosphorus is the second most essential macronutrient in terms of limiting plant growth, acquired in the form of orthophosphate (Pi) by plant roots. The intricate processes of sensing, uptake, transport, storage, utilization, and cellular compartmentalization of Pi are finely orchestrated by a complex network of transporters and their regulators. The plant’s Pi status, encompassing both […]
Phosphorus (P) is an essential nutrient and critical component of nucleic acids, phospholipids, and other molecules. Yang et al. provide a historical (since 1996) overview of the processes controlling its uptake and use. Plants take up P from the rhizosphere primarily in the form of orthophosphate (Pi). However, Pi in the soil often complexes with […]
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 essential for basal immunity and systemic acquired […]
