Biomolecular condensates at the plasma membrane: Insights into plant cell signaling

Biomolecular condensates, often formed through liquid-liquid phase separation (LLPS), are increasingly recognized as a critical mechanism for cellular compartmentalization across diverse biological systems. Although traditionally considered membrane-less entities, recent discoveries highlight their dynamic interactions with membranes, where they regulate various processes, including signal transduction. Signaling lipids are observed in condensates. Despite these advancements, our understanding of such condensates in plant biology remains limited. This review highlights recent studies involving membrane-associated condensates in plants, focusing particularly on their interactions with the plasma membrane (PM) and their potential roles in PM-based signaling.
