The biosynthesis of the herbicide cornexistin in the fungus Paecilomyces variotii was investigated by full sequencing of its genome, knockout of key genes within its biosynthetic gene cluster and isolation and identification of intermediate compounds. The general biosynthetic pathway resembles that of byssochlamic acid and other nonadrides in the early stages, but differs in requiring fewer enzymes in the key nonadride dimerisation step, and in the removal of one maleic anhydride moiety.

Connecting genomic results for psychiatric disorders to human brain cell types and regions reveals convergence with functional connectivity.

Identifying cell types and brain regions critical for psychiatric disorders and brain traits is essential for targeted neurobiological research. By integrating genomic insights from genome-wide association studies with a comprehensive single-cell transcriptomic atlas of the adult human brain, we prioritized specific neuronal clusters significantly enriched for the SNP-heritabilities for schizophrenia, bipolar disorder, and major depressive disorder along with intelligence, education, and neuroticism. Extrapolation of cell-type results to brain regions reveals the whole-brain impact of schizophrenia genetic risk, with subregions in the hippocampus and amygdala exhibiting the most significant enrichment of SNP-heritability.

Nanoparticles play a significant role in enhancing crop yield and reducing nutrient loss through precise nutrient delivery mechanisms. However, it is imperative to ascertain the specific plant physiology altered by these nanoparticles. This study investigates the effects of green-synthesized nanoparticles, specifically boron nitride and sulphur, on sunflower yield, seed quality, and physiological activities.

The tumor microenvironment (TME) is characterized by several key features, including hypoxia, elevated levels of hydrogen peroxide (HO), high concentrations of glutathione (GSH), and an acidic pH. Recent research has increasingly focused on harnessing or targeting these characteristics for effective cancer therapy. In this study, we developed an innovative composite bio-reactor that integrates genetically engineered bacteria with upconversion nanoparticles (UCNPs) and nano-copper manganese materials for lung cancer treatment.

The knowledge on the life cycle of flaviviruses is still incomplete, and no direct-acting antivirals against their infections are clinically available. Herein, by screening via a Zika virus (ZIKV) replicon assay, we found that the N-terminus of NS2A exhibited great tolerance to the insertions of different split fluorescent proteins (split-FPs). Furthermore, both ZIKV and dengue virus encoding a split-FP-tagged NS2A propagated efficiently, and the split-FP-tagged ZIKVs had good genetic stability.

Xanthine nucleosides play a significant role in the expansion of the four-letter genetic code. Herein, 7-functionalized 8-aza-7-deazaxanthine ribo- and 2'-deoxyribonucleosides are described. 2-Amino-6-alkoxy nucleosides were converted to halogenated 8-aza-7-deazaxanthine nucleosides by deamination followed by hydroxy/alkoxy substitution.
