Decoding GUN1 in plastid‐to‐nucleus signaling: what it doesn't, what it does, and why it matters
Publication history of plant GUN1 research. Summary Plastid‐to‐nucleus retrograde signaling coordinates nuclear gene expression with the developmental and physiological state of plastids. GENOMES UNCOUPLED 1 (GUN1), a chloroplast‐localized PPR‐SMR protein, remains a central yet poorly understood component of this network.

Ralstonia solanacearum suppresses P450 activity to block VA‐to‐VanA conversion, leading to VA accumulation and compromised immunity. ABSTRACT Soil acidification often exacerbates plant diseases caused by soil‐borne pathogens like Ralstonia solanacearum, but the underlying molecular mechanisms remain elusive. This study unveils a sophisticated metabolic

Tolerance to Phosphorus Deficiency Improves Seed Phytic Acid‐to‐Iron Molar Ratios in Common Bean
ABSTRACT Although significant advances have been achieved in the biofortification of common beans to overcome deficiencies in Zinc (Zn) and iron (Fe), the mechanisms involved remain poorly understood. We thus explored the relationships between phosphorus nutrition and Zn and Fe accumulation in four bean genotypes (Edar, Nizok, Colorado and Chimbolos ...

Discovery and Biosynthesis of the Novel Glycotetrapeptide Antibiotic Biffamycin A
Genetic de‐regulation of a silent biosynthetic pathway allowed isolation and characterisation of a novel glycopeptide antibiotic named biffamycin A, which harbours unprecedented 5‐chloro‐4‐methoxy tryptophan and 3R‐hydroxy(α‐D‐mannoysl)‐D‐lysine moieties and is bioactive against MRSA and VRSA.

Analyses of cytochrome P450 1a (CYP1A)‐knockout (KO) Javanese medaka (Oryzias javanicus) revealed that CYP1A is involved in glucose regulation and reproduction. In the KO fish, significant increases in hepatic transcripts of insulin, glucagon, and somatostatin genes, as well as elevated blood glucose, liver mass, and liver triglyceride levels ...

Crystal Structure and Conformational Dynamics of N─N Bond‐Forming Piperazate Synthase
Piperazate synthases (PZSs) catalyze the key N─N bond formation in the biosynthesis of the rare amino acid piperazic acid. X‐ray crystal structures of apo‐ and holo‐SbPZS show a dimeric enzyme with two heme‐containing active sites, where histidine residues coordinate the iron centers.

Four isostructural complexes (C1–C4) derived from 2‐(tert‐butoxy)‐6‐(1H‐imidazol‐1‐yl)pyridine with axial halides exhibit octahedral trans M(L)4X2 geometries, confirmed by X‐ray diffraction. They feature a discrete 1,6M7−1 topology, identified using ToposPro analysis.

Stereoselective Biotransformation: Transfer of Learning to Advance Drug Metabolism and Biocatalysis
Understanding stereoselective biotransformations has implications for predicting drug disposition and response and may also inspire novel biocatalytic and biomimetic strategies to address challenges in metabolite and API synthesis. ABSTRACT Chirality is an important determinant of drug action, as enantiomers can exhibit markedly different ...
