Osteohistología e implicaciones locomotoras a partir de una tibia de dinosaurio ornitópodo de la Formación El Castellar (Cretácico Inferior, Teruel)

Geogaceta
El estudio de la osteohistología en dinosaurios permite evaluar patrones de crecimiento y su relación con cambios biomecánicos. En este trabajo se analiza una tibia asignada a un iguanodontio indeterminado del yacimiento Masía de los Cerezos (Formación ...

Opening the black box: in situ imaging of arbuscular mycorrhizal fungal structures in soil using synchrotron‐based micro‐CT

New Phytologist, Volume 251, Issue 6, Page 3687-3702, September 2026.
Summary Arbuscular mycorrhizal fungi (AMF) contribute to plant nutrient and water uptake via their extraradical hyphal networks. However, in situ methodologies to quantify architectural and morphological traits of these networks in soil are largely lacking, limiting our understanding of AMF‐mediated resource transport.

Coupling and robustness of intra-cortical vascular territories [PDF]

, 2012
Vascular domains have been described as being coupled to neuronal functional units enabling dynamic blood supply to the cerebral cyto-architecture. Recent experiments have shown that penetrating arterioles of the grey matter are the building blocks for ...

RGF signaling bridges root development and nonlethal thermal stress adaptation

New Phytologist, Volume 251, Issue 5, Page 2656-2671, September 2026.
Nonlethal high temperature inhibits root growth. Summary Roots adapt to growth‐restricting but nonlethal high temperatures. Although lethal heat shock and moderately elevated temperatures have been extensively studied, the effects of nonlethal thermal stress on root development remain unclear.

Systemic acquired resistance: an emerging role for jasmonates in local signal biogenesis, translocation and distal signal decoding

New Phytologist, Volume 251, Issue 6, Page 3142-3158, September 2026.
Jasmonate signalling underpins establishment of plant systemic acquired resistance (SAR). Activation of the hypersensitive response (HR) not only contains the pathogen but establishes broad spectrum resistance in unchallenged leaves. The strong burst of reactive oxygen/nitrogen species initiating the HR results in lipid peroxidation (illustrated by ...

Partial mycoheterotrophy: a common strategy in arbuscular mycorrhizal plants?

New Phytologist, Volume 251, Issue 6, Page 3096-3110, September 2026.
Proposed autotrophy to mycoheterotrophy continuum among arbuscular mycorrhizal plants. Summary The vast majority of land plants transfer part of the organic carbon they produce by photosynthesis to arbuscular mycorrhizal (AM) fungi inside their root cells; the fungi in turn help plants to take up nutrients and water from the soil.

Cretaceous moss–cyanobacteria association reveals trophic interactions in polar forests of Antarctica

New Phytologist, Volume 251, Issue 6, Page 3627-3639, September 2026.
Kimmerera cyanifera gen. et sp. nov. with associated cyanobacteria, holotype UWBM 116051. Summary Through symbiotic associations with microbes, mosses play many important ecological roles in terrestrial ecosystems, such as facilitating trophic interactions and nitrogen cycling.

Embryonic cortical neural stem cells migrate ventrally and persist as postnatal striatal stem cells [PDF]

, 2006
Embryonic cortical neural stem cells apparently have a transient existence, as they do not persist in the adult cortex. We sought to determine the fate of embryonic cortical stem cells by following Emx1(IREScre); LacZ/EGFP double-transgenic murine cells ...
