Highly heterozygous Citrus changshan‐huyou Y. B. Chang originated from ancient hybridization between mandarin and pummelo and displayed distinct tissue‐specific allelic imbalance

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract The genus Citrus is characterized by a reticulate evolutionary history with frequent hybridization, making it an intriguing subject for genome evolution investigation. Citrus changshan‐huyou Y. B. Chang (Huyou) is a unique landrace first discovered in Zhejiang Province, China, with premium fruit quality.

Acremolin, a stable natural product with an antiaromatic 1H-azirine moiety? A structural reorientation [PDF]

, 2012
Recently, acremolin (4), a novel modified base, was isolated from a marine-derived fungus and claimed to possess a structure with a 1H-azirine moiety. It is shown now that the reported NMR data are not compatible with this antiaromatic heterocycle, which

isoQUINOLINE DERIVATIVES. PART III

, 1957
In contrast with the earlier observation (Ghosh and Dutta, this Journal, 1955, 32, 17, 755) that treat­ment of (a-acetamido-β-phenyl)-etbylmethyl ketone and of β-phenyl-substituted analogues with POCI3 or conc. H2SO4 leads to the formation of I-methylisoquinoline derivatives, accompanied with dehy­drogenation and deacetylation, (α-scetamido-β-phenyl ...

Three Closely Related Spodoptera Species Similarly Affect Gene Expression and Phytohormone Levels but Differentially Induce Volatile Emissions in Maize

Plant, Cell &Environment, Volume 49, Issue 5, Page 2394-2412, May 2026.
ABSTRACT Plants can perceive specific elicitors in the oral secretions (OS) of herbivorous insects and respond by increasing their defences. Whether plants can discriminate among similar herbivorous insect species and differentially modulate their defence responses against them is largely unknown.

Inhibitors of the Detoxifying Enzyme of the Phytoalexin Brassinin Based on Quinoline and Isoquinoline Scaffolds

Molecules, 2017
The detoxification of the phytoalexin brassinin to indole-3-carboxaldehyde and S-methyl dithiocarbamate is catalyzed by brassinin oxidase (BOLm), an inducible fungal enzyme produced by the plant pathogen Leptosphaeria maculans.

Recent Developments in Sustainable Solubilization

ChemSusChem, Volume 19, Issue 8, 28 April 2026.
We highlight several recent developments in sustainable solubilization. Particular attention is given to the use of bio‐based solvents derived from renewable resources, the strategic use of water as a solvent, and alternative, sustainable solubilizers such as hydrotropes.
