Tropane alkaloids in food

Élelmiszervizsgálati Közlemények, 2023
Tropane alkaloids occur in many plant families and their toxic effects can cause mild symptoms or even death, depending on the dose. They are most commonly introduced into the human body through contamination, misuse or deliberate abuse due to their intoxicating effects.

Convergence and parallelism in the evolution of plant metabolism

Journal of Integrative Plant Biology, EarlyView.
Similar traits in different organisms may originate from shared ancestry or evolve independently. The terminology used to define phenotypic similarity is often confusing. This review attempts to clarify the definitions and present examples from plant domestication and specialized metabolism to explain how complex traits evolve repeatedly in plants ...
