With the ongoing climate change, water stress is prone to become a commonplace event leading plant growth and productivity worldwilde under threat because of the disruption of their water status. Forests are highly sensitive to climate change due to the lack of sufficient knowledge related to tree adaptive responses to environmental fluctuations. Structural and physiological adaptations to drought require complex interactions between anatomy, physiology and biochemistry. Thus, long term maintenance of hydraulic integrity is crucial for survival of tree, including important forestry species that are widely distributed worldwide such as Eucalyptus camaldulensis. Xylem, the main pathway for water transport over long distances of this species, is made of solitary vessels surrounded by different imperforate tracheary elements and parenchyma that may influence in a poorly known way their xylem safety and hydraulic efficiency.
