Quantifying the Electrophilicity of 9(10H)‐Phenanthrenone‐ and 1‐Acenaphthenone‐Derived α, β‐Unsaturated Ketones

Journal of Physical Organic Chemistry, Volume 39, Issue 2, February 2026.
The electrophilicities (Mayr E) of the α, β‐unsaturated ketones A and B were determined by kinetic studies of their reactions with carbanions (reference nucleophiles) in DMSO at 20°C. The different reactivities of A and B were rationalized by DFT calculations.

The Factors Involved in Plant–Insect–Microbe Interactions Expanded: Genome Analysis and Description of Frigoribacterium adelgis sp. nov.

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Aerobic Actinobacteria belonging to the genus Frigoribacterium were isolated from adelgid Adelges (Aphrastasia) pectinatae collected from a Korean fir tree. Genomic analysis showed that these bacteria encode a range of factors that may be involved in the interactions between Frigoribacterium strains, adelgids and/or Korean fir trees.

Intrinsic Factors Influencing Simvastatin and Simvastatin Acid Pharmacokinetics: Age‐Related Studies in Thai Adults and Cross‐Population Comparisons

Clinical and Translational Science, Volume 19, Issue 2, February 2026.
ABSTRACT Intrinsic factors such as age and ethnicity influence statin pharmacokinetics (PK) and may increase the risk of muscle‐related adverse events. This study investigated the effect of age on the PK of simvastatin (SV) and its active metabolite, simvastatin acid (SVA), in healthy Thai subjects using an LC–MS/MS assay while accounting for key ...

Evolution of molecular communication in the permanent Azolla symbiosis

New Phytologist, Volume 249, Issue 4, Page 1666-1674, February 2026.
Summary Heritable symbioses exist across eukaryotes with different degrees of intimacy. In most cases, the symbionts are obligate and require inheritance for their survival. On the host side, symbiont retention can facilitate fitness benefits. Only rarely are these symbioses interwoven to the point that host survival relies on the symbiont.

Root cell wall plasticity in iron homeostasis: an overlooked frontier in plant nutrition

New Phytologist, Volume 249, Issue 4, Page 1699-1708, February 2026.
Summary Iron (Fe) is an essential micronutrient for plant growth and development, yet its availability in soils is often limited or excessive, leading to widespread Fe deficiency or toxicity that constrains crop productivity. While Fe uptake, transport, and signaling pathways have been well characterized, the role of the root cell wall as a dynamic ...
