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.

Can species adapt to drought using multiple strategies? Lessons from the California poppy
New Phytologist, Volume 250, Issue 5, Page 2918-2932, June 2026.Summary Plants can escape drought by completing life cycles early, tolerate drought by increasing physiological limits, or avoid drought stress by obtaining or using water more efficiently. It remains unclear whether strategies vary within species across their distributional ranges due to trade‐offs, and whether species can exhibit plasticity in ...

New Phytologist, Volume 250, Issue 5, Page 3486-3498, June 2026.Summary Plant root‐associated anoxic microsites may influence the fate of nutrients and contaminants in the rhizosphere, but their dynamics remain relatively unknown. To examine the formation of root‐induced anoxic microsites over space and time, we use microfluidic devices integrated with transparent, planar oxygen sensors in a wheat (Triticum ...

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 ...

New Phytologist, Volume 250, Issue 5, Page 3212-3229, June 2026.Summary Phosphate (Pi) is an essential nutrient for plant growth, and understanding how Arabidopsis thaliana root cells respond to Pi deficiency is crucial to decipher whole plant responses. We perform high‐resolution transcriptomic profiling across five distinct root cell types, identifying differentially expressed genes (DEGs) and differential ...

Somatic genome‐doubling is the most parsimonious route to allopolyploidy
New Phytologist, Volume 250, Issue 5, Page 2845-2851, June 2026.Summary The origin of a polyploid can hinge on a single errant cell division, a mistake in the cell cycle that leads to genome‐doubling and re‐writes the rules of chromosome pairing and segregation. In plants, the evolutionary significance of these errors is magnified by lack of an early sequestered germline, meaning somatic mutations can be heritable.
