Convergent Evolution and De Novo Reconstitution of Apiin Biosynthesis

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2562-2575, April 2026.
ABSTRACT Apiin, an active flavonoid apioside, occurs in phylogenetically distant plants, such as parsley and chilli pepper (Capsicum annuum L.). Its sporadic distribution suggests the existence of convergent apiin biosynthesis; however, the molecular mechanisms underlying this convergence remain unclear.

3‐Methyl‐1‐Butanol Enhances Postharvest Resistance of Red Grapes to Botrytis cinerea by Activating Phenylpropanoid Metabolism and Antioxidant Defences

open access: yesPlant Biotechnology Journal, Volume 24, Issue 4, Page 2673-2684, April 2026.
ABSTRACT Grey mould, caused by Botrytis cinerea, is a significant postharvest disease leading to substantial economic losses in the grape industry. This study investigated the regulatory mechanism of 3‐methyl‐1‐butanol (3M1B), a yeast volatile substance, on B. cinerea resistance in red grapes (Vitis vinifera L.).

Electrochemical Three‐Component Synthesis of Vinyl Sulfonamides via Decarboxylative Sulfonylation of Cinnamic Acids

open access: yesChemSusChem, Volume 19, Issue 6, 27 March 2026.
An efficient, metal‐free electrochemical three‐component reaction of cinnamic acids, SO2, and amines to access (E)‐β‐styryl sulfonamides is reported. Utilizing graphite electrodes and SO2 stock solutions, this decarboxylative protocol proceeds under mild conditions with high regio‐ and stereoselectivity.
