Molecules, 2018 Phoma-like fungi are known as producers of diverse spectrum of secondary metabolites, including phytotoxins. Our bioassays had shown that extracts of Paraphoma sp. VIZR 1.46, a pathogen of Cirsium arvense, are phytotoxic.

Angewandte Chemie International Edition, Volume 65, Issue 4, 22 January 2026.The strobilurin iterative PKS assembles a remarkable EZE triene by varying its stereoselectivity during synthesis. Stereoselective 2R‐methylation of the triketide intermediate by the C‐terminal C‐methyltransferase domain induces the KR and DH domains to invert their native stereoselectivities and produce a Z‐configured intermediate.

Detoxification of Mycotoxins through Biotransformation
Toxins, 2020 Mycotoxins are toxic fungal secondary metabolites that pose a major threat to the safety of food and feed. Mycotoxins are usually converted into less toxic or non-toxic metabolites through biotransformation that are often made by living organisms as well

Chemical Characterization and Allelopathic Effects of Ambrosia psilostachya (Asteraceae)
Chemistry &Biodiversity, Volume 23, Issue 1, January 2026.ABSTRACT Ambrosia spp. have been introduced and distributed across different continents as an invasive alien plant species. The present study aimed to identify the chemical components of essential oil isolated from different parts of Ambrosia psilostachya and evaluate the phytotoxic effect of its aqueous extracts on the growth parameters of Phaseolus ...

The Arabidopsis deNADding Enzyme DXO1 Modulates the Plant Immunity Response
Plant, Cell &Environment, Volume 49, Issue 1, Page 32-50, January 2026.ABSTRACT DXO1, the only DXO homolog in Arabidopsis, due to its plant‐specific features, exhibits strong deNADding enzymatic activity but has no apparent role in 5′ QC. Despite its important contribution to plant RNA metabolism, the direct impact of DXO1 enzymatic activity on cellular processes appears surprisingly limited.
