Identification and Functional Characterization of Isoflavone synthase Gene Family in Pea (Pisum sativum): The Entry Point to Pisatin Biosynthesis

open access: yesLegume Science, Volume 8, Issue 2, June 2026.
ABSTRACT Isoflavone synthase (IFS), a cytochrome P450 monooxygenase of the CYP93C subfamily, catalyzes the conversion of flavanones into isoflavones, the first committed step in the biosynthesis of isoflavonoid phytoalexins. In pea (Pisum sativum L.), the phytoalexin pisatin plays a pivotal role in defense against pathogens.

Genetic control of wheat flour end‐use quality and rheology by genome‐wide association studies

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Improving end‐use quality in bread wheat (Triticum aestivum) requires dissecting the genetic basis of complex processing traits and deploying robust prediction pipelines in breeding. We performed genome‐wide association studies (GWASs) using 1767 high‐quality single‐nucleotide polymorphisms generated by genotyping‐by‐sequencing in a diverse ...

Transient [3,3] Cope rearrangement of 3,3-dicyano-1,5-dienes: computational analysis and 2-step synthesis of arylcycloheptanes. [PDF]

open access: yes, 2018
A simple and modular route to arylcycloheptene scaffolds is reported. The two-step route from Knoevenagel adducts and allylic electrophiles is made possible through the design of a Cope rearrangement that utilizes a "traceless" activating group to ...

Exploring 6‐Hydroxy‐3‐Aryl/Heteroarylcoumarins as Promising Candidates Against Trypanosoma cruzi

open access: yesChemMedChem, Volume 21, Issue 9, 14 May 2026.
New therapies are urgently needed for Chagas disease, and screening of 6‐hydroxy‐3‐aryl/heteroarylcoumarin derivatives identified highly selective compounds with potent activity against T. cruzi. In particular, derivative 1f showed submicromolar trypomastigote potency, dual‐stage activity, and inhibition of amastigote‐to‐trypomastigote differentiation,
