TL;DR
Recent advances in plant nutrient signalling during development are reviewed, focussing on how carbon and nitrogen signals inform shoot apical meristem activity and the emerging idea that meristem regulators may reciprocally influence nutrient signalling pathways and metabolism is considered.
Abstract
Plant development relies on a complex network of transcription factors and hormone signalling pathways that guide pattern formation and developmental transitions in the meristems. Yet, how this core network is regulated to enable developmental plasticity remains poorly understood. A key question is how information about nutrient availability influences growth decisions, with nutrients acting not only as substrates for energy production and anabolism but also as regulatory signals. Here, we review recent advances in plant nutrient signalling during development, focussing on how carbon and nitrogen signals inform shoot apical meristem activity. We also consider the emerging idea that meristem regulators may reciprocally influence nutrient signalling pathways and metabolism.
It is proposed that chronic low temperature may contribute importantly to this pattern through hormonal regulation, notably reduced gibberellin availability and persistence of DELLA‐like repressors, together with altered auxin and brassinosteroid signaling.

This review explores how PLTs can act as universal architects of plant development and proposes that they confer meristematic potential to tissues, which is primarily determined by their spatiotemporal expression patterns.
