Key Points

This study examines how water and nitrogen are absorbed in poplar tree roots and their interrelated dynamics.
Analyzed spatio-temporal fluctuations in water and nitrogen uptake in poplar trees.
Investigated transporter co-expression to understand the uptake mechanisms.
Explored the role of a gene regulatory network in coordinating uptake.
Water and nitrogen uptake dynamics are tightly coupled in tree roots.
Transporters involved in uptake show significant co-expression patterns.
Gene regulatory networks likely coordinate the uptake processes.

Implication

Reveals coordination of water and nitrogen uptake in Populus × euramericana, suggesting ecological insights.

Abstract

• Water and nitrogen uptake were spatio-temporally fluctuated in poplar trees • Dynamics of water and nitrogen uptake were tight coupled in the roots • Transporters co-expression underpined the coupled uptake of water and nitrogen • The uptake of water and nitrogen was likely coordinated by a gene regulatory network
