Potassium-dependent wood formation in poplar: seasonal aspects and environmental limitations.
Potassium availability and acquisition are pivotal for the generation of biomass and thus wood formation in growing poplar trees. Here, we focus on the role of potassium (K(+)) in wood production, transitions between dormancy and active growth, and limiting environmental conditions. Molecular mechanisms, such as expression and activity of K(+) transporters and channels controlling seasonal changes in wood formation, are discussed.
