Reconfiguring biofortification strategies to transform food systems and address micronutrient deficiency of the 21st century

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2511-2547, August 2026.
This review explores how to make staple foods and horticultural crops more nutritious, including how artificial intelligence‐based screening of gene banks helps deploy nutritionally rich germplasm into breeding. Genome editing can help develop crops richer in minerals, vitamins, and health‐promoting compounds, supporting healthier diets and more ...

Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy

Journal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient

An Overview of Pterin Analysis in Biological Samples: From Occurrence and Properties to Sample Pretreatment Combined With Hyphenated Separation Techniques

Journal of Separation Science, Volume 49, Issue 7, July 2026.
ABSTRACT Pterins are a structurally diverse group of biologically active compounds within the pteridine family, with key roles in pigmentation, redox metabolism, light sensing, and cellular signaling across a wide range of organisms. Their quantification in biological samples is analytically demanding due to their high polarity, chemical instability ...

Functional Stability and the Limits of 16S‐Based Inference in Serpentine Biocrusts

Ecological Research, Volume 41, Issue 4, July 2026.
Serpentine geochemistry and moisture regime shape bacterial biocrust communities in the Barberton Greenstone Belt, South Africa. While coarse taxonomic metrics (alpha and beta diversity) showed no significant differences, ASV‐level analyses revealed strong taxonomic shifts linked to soil chemistry and moisture, with numerous serpentine‐associated taxa ...

Deciphering Cold Stress Resilience: Multiomics Insights in Contrasting Wheat Genotypes From the Western Himalayas

Plant Biotechnology Journal, Volume 24, Issue 7, Page 4577-4598, July 2026.
ABSTRACT Cold stress threatens wheat productivity, particularly in regions with extreme climatic conditions. To elucidate the molecular mechanisms underlying wheat's response to cold stress, we performed a multiomics analysis integrating lipidomics, transcriptomics, proteomics and metabolomics.

Enzymatic Prenylation of Proteins and Peptides: From Cysteine S‐Prenylation to Tryptophan‐Selective Biocatalysis

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
This review highlights biocatalytic prenylation as a versatile strategy for tailoring the functional properties of peptides and proteins. By comparing branched isoprenoids with linear lipids, we illustrate how specific prenyl architectures modulate the behaviors of lipidated proteins within membrane environments.
