Plant, Cell &Environment, EarlyView.ABSTRACT Sorghum anthracnose caused by Colletotrichum sublineola (C. sublineola) is a destructive disease leading to severe crop damages. Pterostilbene is a phytoalexin that contributes to defence responses in sorghum, but the transcriptional regulation of its biosynthesis remained poorly understood.

Plant, Cell &Environment, EarlyView.ABSTRACT Plants are dynamic chemical factories that produce diverse specialised metabolites essential for growth, defence, and environmental adaptation. Metabolomes, shaped by genetic architecture, enable plants to respond to abiotic and biotic pressures, including temperature fluctuations.

Flavone Hybrids and Derivatives as Bioactive Agents
Applied SciencesHybrid molecules can be defined as chemical entities with two or more structural domains, namely pharmacophores, having a specific biological effect. In many cases, when at least one of the components is biologically inactive, it is rather correct to ...

Advances in organic UV filters for sunscreens over the past decade
Photochemistry and Photobiology, EarlyView.Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Almost 200 years of anthocyanin research: What we know, what we assume and what remains unknown
Plant Biology, EarlyView.Nearly 200 years of anthocyanin research reveal a well‐understood anthocyanin biosynthetic pathway. However, there are still open questions regarding its evolution, functions and ecological significance. Abstract Flavonoids are frequently presented as health‐beneficial plant metabolites, and their subclass anthocyanins is best known for striking flower
