Evaluating maturity of organic matter in hydrated C1 and CM‐like clasts and a dehydrated clast within a polymict eucrite and a howardite

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Volatile‐rich xenolithic clasts in different types of brecciated meteorites represent unique pristine solar system material. This study investigates the maturity and thermal history of organic matter using Raman spectroscopy and aqueous alteration effects using infrared spectroscopy in the matrix of 15 volatile‐rich clasts (C1 and CM‐like ...

Geology of the central uplift of the Kamestastin Lake impact structure, Labrador, Canada

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The ~28 km Kamestastin (Mistastin) Lake impact structure is a relatively well‐preserved and well‐exposed complex impact structure. The central uplift of this structure is accessible as two islands in the middle of Kamestastin Lake. We present an updated, detailed geological map and description of Horseshoe and Bullseye islands that provides ...

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

Barley HvBODYGUARD1 controls cuticular specialisations regulated by SHINE transcription factors

open access: yesNew Phytologist, EarlyView.
Cuticle defects result from defective HvBDG1 alleles. Summary Land plants secrete a protective outer cuticular layer with diverse functions. Barley (Hordeum vulgare L.) develops two cuticular specialisations: the β‐diketone rich wax bloom on vegetative tissues and an adherent grain surface which sticks to the hulls, leading to barley's distinctive ...

CNGCs in Marchantia paleacea uncouple arbuscular mycorrhizal symbiosis and rhizoid development

open access: yesNew Phytologist, EarlyView.
Rhizoid growth and AM fungal infection are uncoupled. Summary In Marchantia paleacea, MpaDMI1‐dependent nuclear Ca2+ oscillations are essential for arbuscular mycorrhizal (AM) fungal colonisation, indicating that endosymbiosis‐mediated nuclear Ca2+ signalling is a conserved feature of land plant–AM symbiosis.
