Symplastic and apoplastic pathways for local distribution of silicon in rice leaves
New Phytologist, Volume 247, Issue 3, Page 1280-1289, August 2025.Summary Silicon (Si) is highly accumulated in both the leaf blade and sheath of rice, but the transporter mediating the local distribution of Si between these two tissues remains unidentified. We investigated the role of an aquaporin, OsLsi6, in the local distribution of Si in rice leaves.

Unraveling water pathways and sources in leafless maples during early spring sap ascent
New Phytologist, Volume 247, Issue 3, Page 1172-1185, August 2025.Summary Maple trees repair cold‐induced embolism by generating positive stem pressure during their leafless state, altering sap transport in ways that remain poorly understood. This xylem pressure also drives sap exudation, enabling maple sap harvest for syrup production.

Biosilicification in monocots: Comparative analysis highlights contrasting patterns of deposition
American Journal of Botany, Volume 112, Issue 7, July 2025.Abstract Premise New insights into biomineral uptake and sequestration are important for understanding how plants grow. Some plants accumulate silica accretions in precise locations in particular cells. Among monocots, controlled biosilicification occurs in several different forms and is restricted to commelinids and orchids. Methods We utilized energy‐

Exogenous sugar addition can exacerbate root carbon limitation in trees
New Phytologist, Volume 247, Issue 2, Page 577-594, July 2025.Summary In most tree species, roots serve as major carbon (C) sinks, where C is depleted first when C assimilation is limited. Recent methodological advancements in sugar infusion allow for a better understanding of physiological processes alleviating root C limitation.

New Phytologist, Volume 246, Issue 5, Page 2075-2083, June 2025.Summary Silicon (Si) has been hypothesized to be a metabolically cheaper substitute for carbon‐based cell wall components to support leaves. However, how the biomechanical function of Si, deposited as amorphous silica, differs from cell wall components remains untested. Here, we tested the hypothesis that species with higher leaf Si concentrations have
