Single‐ or two‐visits endodontic treatment: Impact of irrigants on surface roughness, microhardness, topography, and fracture resistance of root dentin

open access: yesEuropean Journal of Oral Sciences, Volume 134, Issue 5, October 2026.
Abstract This study evaluated the effect of the number of simulated endodontic treatment visits and the type of irrigant on the surface roughness, microhardness, topography, and fracture resistance of root dentin. Bovine roots were distributed into six groups (n = 14) according to the irrigant and number of treatment visits: 0.9% saline solution ...

Turnip mosaic virus utilizes the lipid droplet biogenesis machinery to facilitate its propagation in plants

open access: yesNew Phytologist, Volume 252, Issue 2, Page 797-816, October 2026.
Potyvirus turnip mosaic virus induces neutral lipid accumulation and lipid droplet biogenesis in infected leaves for its own benefit. See also the Commentary on this article by May & Nagy, 252: 525–527. Summary Lipid droplets (LDs), which are dedicated to storing neutral lipids (NLs), are dynamic organelles involved in numerous other functions ...

Linking biosurface reactivity and photosynthesis to investigate Sphagnum mosses as ecosystem engineers

open access: yesNew Phytologist, Volume 252, Issue 1, Page 69-86, October 2026.
Habit photographs of field‐collected and in vitro‐cultivated (c) Sphagnum spp. used for experiments. Summary Sphagnum mosses regulate peatland carbon storage, hydrology, nutrient cycling, and ecosystem functioning. However, the links among their surface chemistry, photosynthesis, responses to submersion and pH remain poorly understood.

Phosphorus addition shifts elevated CO2 effects on soil respiration from rhizosphere to root pathways in a mature eucalypt woodland

open access: yesNew Phytologist, Volume 252, Issue 1, Page 100-113, October 2026.
Summary diagram of the utilization of additional carbohydrates fixed under elevated CO2 belowground in natural low‐phosphorus (P) (a) and P‐fertilized (b) conditions. Soil respiration consists of heterotrophic respiration from microbial activity in bulk soil, autotrophic respiration from fine‐root activity and rhizomicrobial respiration driven by ...

The miR167–ARF8 module coordinates stamen–pistil development and fruit set in tomato

open access: yesNew Phytologist, Volume 252, Issue 2, Page 647-665, October 2026.
SlMIR167a is the functionally prominent SlMIR167 gene in tomato fruit development. Summary Auxin is an important regulator of reproductive development. The families of the AUXIN RESPONSE FACTOR (ARF) genes, important components of the auxin signal, have expanded in flowering plants.
