This review synthesises current knowledge on how light signalling regulates cambial activity, xylem and phloem differentiation, and secondary cell wall formation and elaborate on the molecular interplay between light signalling components and key vascular developmental regulators.
Abstract
Light acts as both the primary energy source for photosynthesis and a pivotal environmental signal that orchestrates plant growth and developmental transitions. The plant vascular system, comprising xylem, phloem, and cambium, dynamically adjusts its development in response to light intensity, quality, and photoperiod. This review synthesises current knowledge on how light signalling regulates cambial activity, xylem and phloem differentiation, and secondary cell wall formation. We elaborate on the molecular interplay between light signalling components and key vascular developmental regulators. Understanding these mechanisms is crucial for deciphering plant adaptation to variable light environments and holds significant potential for enhancing crop resilience and woody biomass yield in the context of global climate change.
Light occupies a singular position in plant biology because it supplies the energy for photosynthetic carbon gain while simultaneously providing information about time, season, canopy proximity, spatial orientation and environmental change. These energetic and informational functions are sensed across different scales...

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.
