Establishment of long-term callus cultures of Deguelia duckeana (Fabaceae) with sustained production of lupane-type triterpenes

This study successfully established a long-term, metabolically stable callus culture system for the endemic Amazonian species *Deguelia duckeana* that consistently produces bioactive lupane-type triterpenes over a 12-year period, offering a sustainable alternative for harvesting these valuable compounds.

Year-round Anopheles funestus (s.l.) larval habitat dynamics: combining drone, pictorial, and conventional surveys in south- eastern Tanzania

This study in south-eastern Tanzania reveals that *Anopheles funestus* (s.l.) larvae persist year-round in large ground pools and rivers driven by environmental factors rather than physicochemical properties, while validating pictorial surveys as a reliable monitoring supplement but highlighting the current limitations of drone technology due to vegetation canopy cover.

How robust are transcriptomics-based points of departure when translated to in vivo doses by kinetic-modeling? A case study with the herbicide pendimethalin using HepG2 and HepaRG cells

This study demonstrates that combining in vitro transcriptomics with physiologically-based kinetic modeling provides robust and biologically plausible estimates of systemic toxicity thresholds for the herbicide pendimethalin, yielding points of departure comparable to traditional regulatory in vivo values while highlighting that uncertainty in toxicokinetic modeling contributes as significantly to prediction variability as the choice of transcriptomic analysis method.

A Universal Untargeted Modification Metabolomics Pipeline for Profiling Plant Metabolite Modifications: Application to Wheat-Fusarium Head Blight Interactions

This study establishes a robust, universal untargeted metabolomics pipeline capable of simultaneously profiling over 20 types of metabolite modifications in complex plant extracts, which was successfully applied to reveal distinct glycosylation, acylation, and glutathionylation dynamics and identify resistance-associated markers in wheat during Fusarium head blight infection.

Deep Branching of Archaea: A Phylogenomic Study Using Five Universal Protein Markers

This phylogenomic study utilizing five universal protein markers and Neighbor Joining analysis suggests that the archaeal species *Thermococcus pelagicus* represents the deepest branching lineage, diverging prior to the common ancestor of Bacteria and Eukaryotes, while placing specific eukaryotic species within the bacterial clade.

Floral nectary and pericarp galls of Sapium glandulosum: Structural convergence and cell wall remodeling

This study demonstrates that the insect *Neolithus fasciatus* induces morphologically convergent galls in the distinct floral nectaries and fruit pericarps of *Sapium glandulosum* through extensive tissue reorganization and specific cell wall remodeling, while retaining organ-specific pectic signatures.

The Transcription Factor SlNAC6 from Suaeda liaotungensis Positively Regulates Stress Tolerance in Transgenic Arabidopsis thaliana

This study demonstrates that the Suaeda liaotungensis transcription factor SlNAC6, which is induced by abiotic stresses and localizes to the nucleus and cytoplasm, positively regulates salt and drought tolerance in transgenic Arabidopsis by enhancing antioxidant enzyme activities, reducing oxidative damage, and upregulating stress-responsive genes.
