Acquisitive root exploration strategies help maintain higher peak sap flux rates during summer drought, but more root biomass does not

New Phytologist, Volume 250, Issue 5, Page 2933-2945, June 2026.
Summary Roots are responsible for soil water uptake, yet little is known about how variation in fine‐root traits relates to whole‐tree water movement, particularly during periods of drought. By combining a 3‐yr dataset monitoring sap flow rates with measures of fine‐root biomass, length, and morphology across 10 tree species, we addressed hypotheses ...

Da Vinci's mischief: xylem conduits in the stems of woody plants do not furcate

New Phytologist, Volume 250, Issue 5, Page 3001-3013, June 2026.
Summary The hydraulic architecture of plants is often modeled as a ‘furcating’ network, in which xylem conduits proliferate in number toward the stem apex, analogous to animal circulatory systems. Yet whether furcation actually occurs within woody stems remains untested, despite major implications for carbon costs and hydraulic efficiency.

Constitutive and inducible oleoresin defenses share genetic architectures and mechanisms in Pinus taeda

New Phytologist, Volume 250, Issue 5, Page 2966-2987, June 2026.
Summary The oleoresin defense system of loblolly pine (Pinus taeda) protects trees from insects and pathogens and is an important source of renewable biofuels and chemicals, but the genetic basis of oleoresin production is poorly understood. We characterized the genetic architecture of oleoresin flow, resin canal number, stem wood terpene content, and ...

The interplay between hydraulic capacitance and stomatal regulation strategy affects soil–plant hydraulics and transpiration

New Phytologist, Volume 250, Issue 5, Page 2988-3000, June 2026.
Summary Plant water storage contributes to transpiration, but it is unclear how its relevance in supporting transpiration depends on the stringency of stomatal regulation. Here, we show the compounding effect of stomatal regulation and hydraulic capacitance on plant water use, by means of a soil–plant hydraulic model and measurements of leaf water ...

Tomato plants control leaf sodium levels to limit damage by Spodoptera littoralis larvae

New Phytologist, Volume 250, Issue 5, Page 3417-3427, June 2026.
Summary Sodium is an essential element for animal growth and survival. Here we test the hypothesis that plants exposed to insect feeding can translocate sodium from the feeding site to other plant organs as a defense strategy against phytophagous insects, which need sodium in their diet.
