In search of function: nuclear bodies and their possible roles as plant environmental sensors

Plants must adjust their physiology, development and reproductive decisions in response to a fluctuating environment. Understanding how these adjustments are achieved is fundamental for predicting plant reactions to global environmental changes and for designing mitigation strategies. An often overlooked plant-environmental response is the formation of intranuclear membrane-less organelles known as 'nuclear bodies'. Currently, the functional role of nuclear bodies remains largely unclear. However, in recent years, they have received increased attention as possible hubs or integrators of environmental signals, and for possibly being part of the sensing machinery itself. Here, we will explore the formation of nuclear bodies under changing light, osmotic, and temperature conditions. We will then hypothesize on their potential functions in facilitating environmentally driven plant responses.
