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 phytohormone essential for basal immunity and systemic acquired resistance; however, its […]
Genome editing stands at the forefront of scientific innovation, offering transformative possibilities to manipulate the genetic code of plants, animals, and humans. A critical bottleneck for its application in modern crop improvement is the low frequency and error-prone integration of foreign DNA into the plant genome. While the rapid development of CRISPR/Cas system, which functions […]
Phosphorus (P) is an essential nutrient for plant growth and development. Under P deficiency, white lupin develops cluster roots (CR), specialized root structures that enhance soil exploration and nutrient acquisition. While sugar signaling, particularly sucrose, has been shown to play a role in the establishment of CR, other CR-associated features such as the root exudation […]
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 include receptor-like kinases (RLKs), receptor-like proteins (RLPs), and receptor-like cytoplasmic kinases (RLCKs). The genomes […]
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 elements, including microRNAs and the ubiquitylation system. Intriguingly, mounting evidence indicates that beyond the traditional roles […]
Nitrogen (N) is vital for plant growth, with plants typically absorbing inorganic N compounds like nitrate (NO3−) and ammonium (NH4+) from the soil. Yet plants can also utilize organic N sources, including amino acids like glutamine (Gln). Gln, as the first organic N compound assimilated within plant cells, goes beyond its metabolic function, influencing various […]
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 […]
